Senior Software Engineer - AI Data (MX)

$2,400/week · 40 hours a week · Paid weekly · Fully remote · 4+ years experience

About the role

Frontier AI labs are building coding agents that do real engineering work. Before these coding agents ship, Senior Engineers have to work a real problem from a codebase they know, step by step, to identify where a frontier model goes wrong then correct it.

Not just anyone can do this. It takes a select group of engineers with experience and taste.

Engineers who qualify join a fixed-pay contract: earn $2,400/wk for 40hrs of work ($60/hr). Work on your own schedule, paid weekly.

What you'll do

• **Judge the AI's work.** Give an agent a real ticket, then review its output like a teammate's pull request: run it, evaluate it.
• **Pair with the AI on your own task.** Work a real problem from a codebase you know, step by step, and flag where the model goes wrong.

**What's in it for you**

• **Senior-engineer pay.** A weekly contract paying $2,400 for a 40-hour week. Work from anywhere, any time.
• **Work that lasts.** This is not a two-week gig. The work is here month after month, and the 40 hours are yours every week you're on the team.
• **An elite, hand-picked team.** You’ll have priority access to the projects frontier labs trust us with, the ones every engineer wants a seat on.
• **Problems that are actually hard.** Your work on difficult tasks goes straight back to the labs training the next best-in-class models.
• **A seat at the table.** You'll work directly with project leads from day one. Your read on where models fail and where the bar should sit shapes how we run these programs.
• **Ongoing, on your schedule.** The contract renews every week while you meet quality standards. You set your hours. Exceptional engineers may be approved for additional hours, paid at $60/hr on top of your base earnings.
• **Support that meets your needs.** A dedicated team, fast answers, and real feedback on your work.

**How it works**

1. Pass a proctored coding assessment, without the use of AI tools. You’ll earn $100 when you pass. About 2 hours.
2. Complete one paid trial task. You’ll earn $40 when you submit your first stage and $440 once it's approved through every review cycle. About 10 hours total.
3. Join the team and continue working. We’ll provide 40 hours of work every week, totalling $2,400.

**You're a fit if you have**

• 4+ years of professional software engineering experience
• A Bachelor's or Master’s degree in computer science or a related field
• Mexico work authorization
• Strong written English and 40 hours a week to give during your contract
• No AI background needed. Your software engineering skills are the whole job.
