Principal Software Engineer – Web Infrastructure (Frontend DevEx)

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.

Who You Are

• Principal-level experience in platform engineering, developer experience, or internal tooling
• Deep hands-on background with Web CI/CD: pipeline design, reliability, build optimization
• Hands-on experience with CDN and edge infrastructure (CloudFront, Lambda@Edge, S3)
• Solid knowledge of modern frontend — React at scale, microfrontends, module federation
• Experience scaling frontend observability: errors, performance, RUM and analytics
• Track record of improving DevEx metrics in the right direction (DORA, DX insights, CSAT)
• Strong instinct for finding systemic friction and solving it pragmatically
• Proven ability to operate independently in a distributed team across a timezone gap
• Hands-on experience applying AI tooling to real engineering workflows
• Based in EST timezone

Nice to have

• Experience with progressive delivery and feature flag platforms
• Experience with test platforms and QA automation
• Familiarity with Kubernetes-based infrastructure and cloud-native deployment patterns
• Prior work on a platform or DX team serving frontend engineers specifically

What You’ll Do

• Own and improve the dev loop for frontend: local dev, build, test — fast, reliable, no flakiness
• Drive CI/CD reliability, speed, and deployment confidence across the frontend platform
• Evolve microfrontend architecture, module patterns, and the standards inside the monorepo
• Build and maintain self-service tooling and internal platform capabilities
• Embed AI across the web SDLC — code authoring, testing, debugging, documentation
• Define, track and improve developer productivity metrics: build time, DORA, developer CSAT
• Identify systemic friction in the developer journey and fix it with solutions that scale
