Senior Trust & Safety Engineer

We started as the place to find a trusted trade. Now, as we shape the future of home improvement, we're building the tech to transform that landscape for everyone - better products, smarter data, AI where it actually helps - so trades can spend less time on admin and consumers can find someone they trust, first time. That's Powering Great Work, and it's why every team here exists:

🔧 Trades spend less time on admin and more on winning work and growing their business

🏠 Homeowners get a trusted trade, first time, every time

🚀 We get to build products that change homes and lives across the country

As our next Senior Software Engineer in Trust & Safety, you'll own the systems that decide how tradespeople are checked, how reviews are processed and how our marketplace stays honest at scale. You'll work alongside the vetting and reviews teams, who are on the front line of trust, and build the infrastructure that lets them work with confidence. When something breaks in production, you'll lead the response. When something looks brittle at design time, you'll say so.

• Strong TypeScript. You're comfortable owning a service end to end, from schema to deployment.
• Fastify or a similar Node.js framework, and enough HTTP know-how that it rarely surprises you.
• Event-driven instincts: you know what idempotency means in practice and why the outbox pattern exists.
• Full-stack comfort, Next.js included. You ship the frontend as happily as the service behind it.
• Datadog fluency (APM traces, log search, metric queries), SQL for diagnostics during an incident, and GCP basics such as Pub/Sub backlogs and DLQs.
• Experience leading production incidents, not just being in them. You communicate clearly under pressure and drive to a fix.
• An eye for systemic problems at review time, not at post-mortem time, and a habit of making the people around you better.
• Regular use of AI tools like Cursor or Claude Code, and a keen interest in helping the team get more out of them.

You don't need to know our Trust & Safety domain yet (the review lifecycle, vetting disposition logic, publish timing). You'll pick it up. What matters is that you learn fast and take it seriously.

(Don't self-select out because you don't tick every box. We'd rather meet you.)
