Come join us! About the Team: Web Infra is part of our Engineering Platforms org. We own the foundation frontend engineers build on: CI/CD, build tooling, observability, feature flags, microfrontend architecture, performance optimisation, and engineering standards across a ~2.8M LOC React monorepo. Every frontend engineer at AlphaSense ships through the platform we build. The decisions we make directly influence engineering velocity, deployment confidence, reliability, and developer experience across the company. We obsess over developer productivity, measuring success through build times, deployment reliability, DORA metrics, and developer satisfaction. The current team is based in Europe, and we’re hiring our first engineer in the US. As the first US-based member of Web Infra, you’ll play a key role in strengthening how the team supports product engineering across the region while contributing to the evolution of our frontend platform. This is intentionally a Principal-level role: you’ll be expected to identify opportunities, set direction, and drive high-impact initiatives with a high degree of autonomy rather than operate from a prescriptive backlog. You’ll work closely with the European team on strategy and roadmap while owning outcomes end-to-end. About the Role: A key part of this role is embedding AI into the SDLC in a way that meaningfully augments engineers' day-to-day workflows. We believe the next generation of engineering productivity will be driven by AI-native development experiences, and you'll help define how frontend engineers at AlphaSense build, test, debug, and ship software at scale.
