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:
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. When something breaks in production, you'll lead the response. When something looks brittle at design time, you'll say so.
Own and evolve the systems behind how tradespeople are verified, how reviews flow through our platform and how content is moderated.
Lead the response when things break: read distributed traces, correlate logs across services and find the cause, not just the symptom.
Design event-driven workflows that are reliable by default: idempotent, retryable, with dead-letter handling that doesn't need a 2am wake-up to unpick.




Work directly with the vetting and reviews teams to understand what trust means day to day, then build systems that hold up to it.
Tighten the operational seams: better monitoring, clearer alerting, locked-down auth and outbox patterns that keep data consistent.
Strong TypeScript. You're comfortable owning a service end to end, from schema to deployment.
Fastify or a similar Node.js framework, and enough 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 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.

Final stage with the hiring manager and a senior stakeholder
We're growing fast, with big plans to become the go-to brand for home improvements. If you care about great work, take pride in the details, and want to make an impact, you'll fit right in.
