Founding Engineer

80% of the workforce doesn't sit at a desk. Their software is a spreadsheet from 2019.

Sira runs scheduling, timesheets, payroll, HR, and invoicing for deskless teams. We started with security guard companies — 50 to 300 officers, 24/7 coverage, payroll that has to be right to the minute or someone doesn't make rent. We replace their ADP + Connecteam + QuickBooks + cousin's spreadsheet stack.

YC S25. Real revenue, real logos.

You'd own whole surfaces. Pick a problem, talk to the customer, ship it, watch someone use it that week. The case for AI workflows has never been clearer, and it's in a product with real customer value. We can change the game, and you'd lead us on the product side, hand in hand.

You're a fit if you've shipped things people depended on and you're obsessed with customers — the kind of person who's in it for the moment someone tells you the thing you built made their day easier.

TypeScript, React/Next, Node, Postgres, AWS.

No good software exists in this industry, we can take on the full market!!!

Interview Process

Under two weeks, start to offer. You get a yes or no within 24 hours at every stage, with a reason.

1. Intro with Nathan, founder/CEO (30 min). Not a screen. What we're building, what you've built, whether the problem space grabs you. You should leave knowing if you want this job.

2. Technical conversation (60 min). No LeetCode, no whiteboard trivia. We walk through something real you shipped — architecture decisions, tradeoffs, what broke, what you'd do differently. Then a real problem from our codebase and how you'd attack it.

3. Paid work session (4–6 hours, on your schedule). You build something small and real against our actual stack. We pay for your time regardless of outcome. Best signal for both of us.

4. Team + customer day. Meet the team and sit in on a live customer call so you see exactly who you'd be building for. Offer within 48 hours.
