Your Tech Job Offer Contract Has Seven Traps. Most Engineers Find Them After They Sign.

You check the salary. You count the RSUs. You calculate the vest schedule. You feel clever. Then you sign.

That's the workflow for most engineers. And for most engineers, it works out fine. Until it doesn't.

The clauses that actually bite in a tech job offer contract are never in the compensation section. They're in the boilerplate at the back, attached as exhibits, or buried in a separate stock option agreement that arrived three emails after the offer letter. Most candidates read them once, understand about half of what they're reading, and sign anyway because the deadline is in 48 hours and the job sounds great and honestly the font is really small.

Here are seven specific things worth five minutes of your attention before you click "agree."

IP Assignment: Your Weekend Project May Already Belong to Someone Else

Every tech employment contract has an IP assignment clause. It says something like: "you assign to the Company all inventions, works, and discoveries made during your employment." Sounds reasonable. The problem is what "during employment" means in practice.

Overly broad versions don't limit assignment to work you did at work. They claim everything you create while you're an employee: the weekend project, the open source library, the app you built on your own laptop at midnight while the company was asleep. The company may never actually want your side project. But if you later sell it, or build a startup on it, that clause gives them standing to argue they own it. Surprise!

Six states explicitly limit this by statute: California, Delaware, Illinois, Minnesota, Washington, and North Carolina. In those states, employers cannot claim inventions you developed entirely on your own time, without company resources, that don't relate to the company's actual business. California Labor Code § 2870 is the strongest example. If you live outside those six states, you have no statutory backstop. The contract language controls.

What to do: ask for the IP assignment to be narrowed to work created using company time, equipment, or confidential information, and that relates to the company's actual business. Most legal teams will accept this. It's already standard at large companies. You're not asking for anything weird.

Prior Inventions: Leaving It Blank Is Not Neutral

Most IP assignment agreements include an Exhibit A or Exhibit B called something like "List of Prior Inventions." It's a blank table with columns for name, description, and date. Most candidates leave it blank because they don't think they have anything worth listing, or because filling it in feels awkward, like listing "cooking" as a hobby on a resume.

Leaving Exhibit A blank is one of the most expensive mistakes you can make signing a tech employment contract. When you leave it blank, you've represented that you have no prior inventions. Anything you later claim existed before your start date now has no evidence behind it. One engineer with 22 years of experience lost rights to a personal app after signing a contract with an all-inventions assignment clause and a blank prior inventions exhibit. He had receipts. He lost anyway.

Before you sign: list every side project, open source contribution, GitHub repository, app, script, or creative work you own and want to keep. Include a name, rough date, and a one-line description. The bar is low. Listing more is not arrogant. It is the only way to protect what you built before you walked in the door.

Training Repayment Agreements: The Clawback You Didn't Notice

Signing bonus clawbacks are well-known. If you leave within a year, you pay back the bonus. Most people know this one.

Less discussed are Training Repayment Agreement Provisions. Labor lawyers who litigate these have a name for them: TRAPs. These require you to repay the cost of training, certifications, or onboarding programs if you leave within a set window, typically six to twenty-four months.

The dollar amounts are real. Some technology companies have attached five-figure repayment obligations to standard compliance training that took eight hours to complete. The CFPB documented TRAPs requiring repayment of up to $10,000 for training programs the employer describes as "specialized." You watched those videos at 2x speed. You still owe ten grand.

The key question: what counts as "training"? Vague language lets companies treat almost any onboarding activity as a reimbursable cost. If the provision isn't limited to genuinely specialized external certifications, with a clear dollar cap and a proration schedule, negotiate or push back.

Washington State banned TRAPs in 2025. California banned stay-or-pay contracts effective January 2026. If you're elsewhere, the clause is probably enforceable.

Non-Competes: The Map Changed, Then Changed Back

Non-compete clauses try to prevent you from working for a competitor for some period after you leave. They used to be standard in tech employment contracts. The legal landscape shifted sharply.

The FTC passed a rule in April 2024 banning most non-competes nationally. Engineers everywhere exhaled. Then a Texas federal court blocked it. Then the Trump administration withdrew the appeals in September 2025. The federal ban is dead. What you're left with is a state-by-state patchwork that requires you to actually look up your state's law.

California, Minnesota, North Dakota, and Oklahoma have largely banned non-competes. Colorado, Illinois, Massachusetts, and Washington restrict them significantly. About 30 states still enforce them if they're "reasonable" in duration and scope. If your offer has a non-compete and you're in California, it's unenforceable. If you're in Delaware, Texas, or Florida, it may follow you to your next job.

Even where non-competes are banned, non-solicitation clauses remain broadly legal. These prevent you from recruiting former colleagues or poaching clients. Watch for language that covers "any current employee" at a 10,000-person company instead of just your direct team.

Equity Repurchase Rights: The Clause That's Not in Your Offer Letter

This is the one that surprises people after the acquisition announcement.

In 2011, Microsoft bought Skype for $8.5 billion. Former Skype employees received nothing. Buried in their option agreements was a provision that let the company repurchase vested shares upon termination at a predetermined price. Employees who had left before the acquisition found their vested shares worth exactly what the company had paid for them on the day they left. Not on the day of the $8.5 billion deal. The day they left.

Equity repurchase rights let a company buy back your vested shares at a price it controls. Typically fair market value of common stock on the date you left, not on the date of any later liquidity event. These clauses appear in stock option agreements, stockholder agreements, and company bylaws. Not in offer letters. If you don't read those documents before signing, you won't find them until after it matters.

What to look for: language about "repurchase rights," "buy-back," or "right of first refusal" on vested shares. Ask whether the company holds any right to repurchase vested shares, under what conditions, and at what price. A right of first refusal at fair market value is different from a unilateral repurchase right at a company-determined price. Sam Altman called forced repurchase of vested shares "horrible" in 2017. It still happens.

Mandatory Arbitration: Your Lawsuit Is Already Decided

Mandatory arbitration clauses require you to resolve employment disputes through a private arbitrator rather than in court. Almost all major tech companies include them. The Supreme Court ruled in 2018, in Epic Systems Corp. v. Lewis, that class action waivers paired with arbitration clauses are enforceable. You waive the right to join a class action the moment you sign. That happened before you got a badge photo.

Practically: if you believe you were underpaid relative to colleagues doing the same work, you bring that claim alone. Not with 200 coworkers. Individual arbitration is expensive, slower than it looks on paper, and statistically favors the employer. Research consistently finds workers recover less in arbitration than in court, and win less often.

The Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act (2022) carved out those specific claims. Everything else remains subject to arbitration if your contract says so.

You probably cannot negotiate this out at a large company. But you can know it's there, understand what it means, and factor it into how much you trust the company's stated culture when the contract comes in.

Who Owns Saturday?

Many contracts include a clause requiring you to disclose outside employment or to obtain written approval before doing any outside work. The stated intent is reasonable: the company doesn't want you freelancing for a direct competitor on their clock.

The problem is drafting. "Any business activity" or "outside employment in the software industry" can sweep in teaching a coding bootcamp, maintaining an open source project, writing technical articles for pay, or consulting one weekend a year. Combined with a broad IP assignment clause, the outside activities clause can turn your side income into a disclosure obligation and your side projects into potential company property.

Read it carefully. If it requires approval for any outside work, ask for narrowing language: something like "outside work that (a) uses company confidential information, (b) directly competes with the company's current business, or (c) materially interferes with your primary role." Most reasonable employers will agree to that. If the legal team fights hard on this, that tells you something about how they approach the relationship.

The Choice of Law Clause Nobody Reads

The choice of law clause specifies which state's laws govern the contract. A Delaware-incorporated company hiring a California-based engineer might specify that Delaware law governs. That matters because Delaware enforces non-competes that California does not.

California has a partial fix: Labor Code Section 925 prevents employers from requiring California employees to litigate claims outside California or under another state's law. But the protection is limited to employees who "primarily reside and work in California." Remote workers who split time across states are more exposed than they realize.

If you live in a state with strong employee protections and your contract specifies the law of a less protective state, ask for your home state's law to govern. This matters most for non-compete and IP clause enforcement. A non-compete you'd easily fight in California might follow you if Delaware law controls.

What to Do Before You Sign

You have a written offer. Here's a practical checklist:

Read the IP assignment clause. Ask for it to cover only work using company resources or related to company business.
Fill out the prior inventions exhibit. List everything. Leave nothing blank.
Ask whether equity repurchase rights exist on vested shares. Request the actual stock option agreement, not just the summary in the offer letter.
Check non-compete enforceability in your state. If you're in a ban state, know it. If you're not, negotiate duration and scope down.
Look for TRAP language. Ask what training costs are subject to repayment and what the dollar cap is.
Check the choice of law clause. Confirm your home state's law governs if that state offers stronger protections.
Understand the arbitration clause scope. You probably can't remove it, but know which disputes it covers.

None of this requires a lawyer for a standard individual contributor role, though a lawyer is worth the cost for senior, staff, and principal offers where equity values are larger. The goal is to read the documents before you're locked in, not after the acquisition announcement lands in your inbox.

The offer letter is designed to be signed fast. The people who read carefully aren't being paranoid. They're protecting work they've already done and income they haven't earned yet.
