Résumé du poste

Swap is building an AI-native storefront platform and needs a Staff Software Engineer to lead multiple engineering teams. You’ll set direction, tackle cross‑cutting problems, and stay hands-on in critical code paths with Product, Design, Data, and leadership.

You’ll drive architectural decisions, mentor engineers, and shape scalable, reliable systems. The role requires deep TypeScript/JavaScript expertise and a track record delivering complex enterprise software.

Qualifications

• Significant experience (typically 8+ years) building and shipping production software, with a record of leading complex initiatives that cross team lines.
• Deep expertise in TypeScript/JavaScript and Node.js, including architecting REST and/or GraphQL APIs and distributed systems.
• Comfort outside your home language and stack. We expect Staff engineers to be T‑shaped.
• Strong relational database, data modelling, and SQL skills, plus familiarity with NoSQL.
• Experience designing for reliability and scale in the cloud, with solid CI/CD, observability, and incident‑response practices.
• Hands‑on experience with LLMs or agentic systems, or a track record of picking up new technology fast and applying it sensibly.
• Daily use of AI coding tools, with a sense for when to trust them and when not to.
• Experience in eCommerce systems and platforms is preferred.
• Excellent written and verbal communication. You can explain trade-offs in business terms to any audience.
• A team player with a bias for ownership: you bring a solution along with the problem, and work isn’t done until it’s live and stable.

Responsabilités

• Lead large initiatives that run for several quarters and involve multiple teams, from first scoping through to production.
• Write exemplar code in critical paths, setting the implementation bar for the wider group.
• Review important designs from other teams, helping engineers balance quality, speed, reliability, and long-term maintainability.
• Define and uphold operational standards for the group: monitoring, availability, scalability, security, release safety, and cost awareness. Help lead serious incidents and follow through on the right fixes.
• Lead tool evaluations and architecture migrations, making build‑vs‑buy trade‑offs explicit.
• Use AI well beyond the basics, and push back on AI‑generated complexity so code health holds as we speed up.
• Own the business result of your work. Define success metrics, monitor after launch, and challenge constructively when something won’t move the needle for merchants.
• Mentor Senior Engineers and below, and lead or join senior‑level interviews.
• Write and improve the documentation others rely on, such as architecture direction, decision records, and runbooks.
