Principal Software Engineer

Suitsupply; Amsterdam; Híbrido; EUR 140.000 - 200.000; Jornada completa

Descripción de la vacante

Suitsupply in Amsterdam is looking for a Principal Engineer to design, build, and ship with our teams, setting engineering standards across domains and ensuring adoption in code, pipelines, and AI-native ways of working.

You will split time between accelerating internal projects and driving cross-cutting standards, partnering with Tech Leads and Engineering Managers to raise the bar without direct reports.

Formación

• 10+ years of engineering with staff- or principal-level scope at a strong product or tech company.
• Experience across at least three domains — not a single silo.
• Hands-on across the stack and shipping code weekly; proficient in at least one: .NET and Azure event-driven backends, large-scale commerce ecosystems, or integration and data platforms.
• Established standards across teams via tooling, guardrails and examples, not decks.
• Experience leading without direct reports; final authority on domain standards.

Responsabilidades

• Set the cross-cutting standards backlog for domains and enforce them in code and deployment.
• Design, prototype and build on hard cross-team problems including migrations, integrations and foundations.
• Jump-start delivery by leading technical discovery and shaping the initial implementation with teams.
• Embed with teams to raise the bar in place, pairing with Tech Leads and Engineering Managers.
• Enforce standards through systems, PR guardrails and automated checks for scalable adoption.
• Drive agentic, AI-native development as the default working mode with Engineering Managers.
• Cover gaps by stepping into teams without a Tech Lead to maintain delivery and quality.
• Collaborate with Engineering Leadership on domain architecture; scale standard adoption.

Descripción del empleo

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: .NET and Azure event-driven backends, large-scale commerce ecosystems, or integration and data platforms.
• You have made standards stick across teams that didn't report to you — through tooling, guardrails and example, not decks.
• Already ahead of us on AI-assisted and agentic development at enterprise scale — multi-team, inside an existing ecosystem. We expect to learn this from you, not to teach it to you — and you can show a team or codebase you made measurably faster.
• You explain hard things simply — to engineers, to product, to the board. If you truly know it, you can say it plainly.
• Zero direct reports, by design — and that suits you. Your authority is technical, and on domain standards it is final.

What you will get:

• Competitive compensation — we benchmark this role against the top of the Dutch tech market, not against retail. A freelance-first start is possible if that is how you work.
• A real top-of-ladder IC seat: final say on domain standards, a direct line to the Head of Engineering and the Director, and no management detour required to keep growing.
• Scale that shows: ~16 product teams, a global Shopify migration, own-built Custom Made and Radical Personal platforms, and an ERP transition — with the mandate to make it all AI-native.
• Autonomy without layers of sign‑off
• Hybrid working: three days in the Amsterdam HQ, two remote — flexible in both directions once you're up to speed.
• A 40% discount on Suitsupply product, and a working wardrobe you'll actually want to wear.
