About the team

The Frontend Platform team creates the foundations that make it easier for engineers to build high-quality product experiences quickly, consistently, and with confidence. We work across shared UI systems, frontend architecture, developer experience, performance, reliability, and the tools that help teams ship well.

This is a team for engineers who enjoy working at a leverage point. Instead of owning a single feature area, we shape the patterns, primitives, and workflows that many teams build on top of. Our work sits at the intersection of product engineering, design systems, and platform thinking, with a strong focus on creating durable solutions that improve the experience for both developers and end users.

We’re still an evolving team with room to define our scope and raise our ambition over time. That makes this an especially strong opportunity for someone who wants to help shape not just what gets built, but how frontend engineering is practiced. We’re excited about modern tooling, including AI-assisted and agentic workflows, and we believe the best engineers use them to extend strong judgment, not replace it.

Alloy operates in a hybrid-work environment. We look to foster collaboration and community by having our local employees onsite three days a week.

What you'll be doing

• Lead the design and delivery of large, ambiguous frontend and platform investments that span multiple teams or product areas

• Shape technical direction across the frontend stack through architecture, standards, and durable shared patterns

• Build and improve both shared frontend foundations and customer-facing product surfaces

• Partner closely with engineering, design, and product to turn broad needs into simple, scalable solutions with meaningful user and business impact

• Raise the quality bar across teams through strong technical judgment, clear documentation, and improvements to developer experience, reliability, and engineering practices

• Help shape effective use of AI and agentic engineering workflows in frontend development to improve leverage, quality, and delivery speed

Who we’re looking for

• You’re a senior frontend engineer with 8+ years of experience, deep fundamentals in JavaScript or TypeScript, modern HTML and CSS, and experience building complex web applications with a modern framework such as React

• You’ve led large, complex frontend or platform initiatives and influenced technical direction beyond your immediate team

• You have strong engineering judgment and know how to balance user experience, product needs, maintainability, operational excellence, and delivery speed

• You’re comfortable operating in ambiguity and can turn loosely defined problem spaces into clear technical direction and execution

• You bring strong product and business context, and use it to influence prioritization and improve customer outcomes

• You use AI-enabled tools thoughtfully and responsibly, with a high quality bar and without outsourcing core engineering thinking

We're a lean team, so your impact will be felt immediately, and opportunities will grow as the company scales up. If this all sounds like a good fit for you, why not join us?
