Principal Engineer

At Suitsupply, we combine radical style with radical technology. We are looking for a Principal Engineer — the most senior hands-on engineer in the company: you design, you build, and you ship alongside our teams. You set the engineering standard for an entire domain, and you make it stick — in the code, in the pipelines, and in how our teams adopt AI-native ways of working. Expect a roughly 50/50 split: half your time accelerating projects inside teams, half driving the cross-cutting standards everyone works to. 

• Set the standard: own the cross-cutting standards backlog for your domains — unified observability and monitoring, alerting, release and deployment processes, CI/CD templates, and shared packages — and make them binding: non-compliant code does not merge. 
• Stay in the code: design, prototype and build on the hardest cross-team problems — the migrations, integrations and foundations no single team can own.
• Jump-start delivery: parachute into projects that need momentum — run the technical discovery, shape the solution, get the first implementation moving with the team. You accelerate teams. 
• Embed, don't tower: work inside teams to raise the bar in place, pairing with Tech Leads and Engineering Managers.
• Enforce through systems: skills-per-repo, PR guardrails and automated checks carry the standard, so it scales without you hand-reviewing every merge.
• Make us AI-native: drive agentic development as the default way of working, on a drumbeat you set with the Engineering Managers.
• Cover the gaps: step into teams without a Tech Lead to keep delivery and quality on track while we hire.
• Pair at the top: partner with Engineering Leadership on domain architecture. You set the standard; the Tech Leads spread it.
