The Team

You’ll join the Frontend Platform Team, a cross-functional engineering team that builds shared systems and components used across all of blp’s Stream-Aligned Teams (SATs).

This includes building:

• Core UI frameworks

• Reusable frontend foundations

• Shared design system components

• Cross-product functionality

This gives you broad impact across the entire platform.

This role is ideal for someone who enjoys architecting clean, scalable frontend systems and empowering multiple product teams at once.

What You’ll Do

Help the team improve on the existing architecture and own its future direction — delivering a highly performant, scalable, AI-ready TypeScript codebase across multiple product teams.

• Drive architectural decisions across the stack: component design, state management, performance budgets, and build tooling.

• Apply deep knowledge of browser internals — event loops, Web Workers, rendering pipelines — to ship fast, responsive document processing UIs.

• Work closely with product and backend engineers to define clean API contracts and integrate smoothly with AI-powered services.

• Mentor engineers through architecture reviews, pairing sessions, and internal documentation that raises the technical bar.

• Tackle cross-cutting concerns: shared libraries, design system consistency, testing strategy, and CI/CD improvements.

• Stay close to the product and its users — and translate that understanding into frontend solutions that are both solid and a pleasure to use.

Tech Stack

Your daily work will focus on:

• TypeScript

• React

• Our evolving design system

• Modern state management

• Modern build tooling (Vite, Webpack)

You will collaborate with backend systems built using:

• Golang

• PostgreSQL / MySQL

• OpenAPI

• Docker & Kubernetes

• GitHub Actions CI/CD

Why You’ll Love Working Here

• High-leverage scope: your work affects every product team and thousands of enterprise end users.

• Remote-friendly with a senior, engineering-focused culture.

• Direct influence over architecture, tooling, and UI foundations.

• Work with senior engineers in a fast-moving but highly technical SaaS environment.

• Autonomy and ownership from day one.

Qualifications

• Bachelor's or Master's degree in Computer Science or equivalent practical experience.

• 5+ years of experience as a full-stack developer with a strong focus on frontend development.

• Experience with modern frontend frameworks, preferably React.

• Deep expertise in TypeScript and modern frontend architecture — you have strong opinions and can back them up.

• Strong understanding of browser internals, including event loops and Web Workers.

• Proven ability to guide teams in architectural decisions and drive their implementation through to production.
