Principal Engineer
About this role
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.
What you will do: 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. Who you are: 10+ years of engineering, with recent staff- or principal-level scope at a strong product or tech company.
You have carried technical responsibility across at least three domains — not one deep silo. This is a hard requirement. You have joined an existing ecosystem and changed it — change management in a landscape you didn't build is core to this job; greenfield-only track records don't clear the bar. Hands-on across the stack and still shipping code weekly; deep in at least one of event-driven backends, large-scale commerce ecosystems, or integration and data platforms.
