Alloy reduces friction for end-users by helping them onboard customers with fewer hoops, keeping their accounts safe with ongoing transaction monitoring, and delivering credit decisions faster. We envision a more dynamic financial industry where the underbanked find more access to the financial products they need. 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.
Requirements
- You’re a senior frontend engineer with 5+ 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 have strong engineering judgment and know how to balance product needs, user experience, long-term maintainability, and delivery speed
- You’ve worked on shared systems before, whether that means design systems, frontend architecture, internal platforms, developer tooling, or other cross-cutting investments
- You care about quality in the broad sense: clean abstractions, accessibility, performance, testing, reliability, and thoughtful user experience
- You’re comfortable operating in ambiguity and can help shape a problem space that is still evolving rather than waiting for every requirement to be fully defined
- You collaborate well across disciplines and communicate clearly with engineers, designers, and stakeholders with different perspectives
- You use new tools thoughtfully. You’re curious about AI-enabled ways of working and can incorporate them into your workflow without outsourcing core engineering thinking
- You’re motivated by leverage and craft: you want to build the systems that help an entire engineering organization do better work
Responsibilities
- Build and improve the shared frontend foundations that other engineers rely on, including reusable components, patterns, tooling, and platform capabilities
- Help define the architecture, standards, and best practices that make our frontend systems more scalable, maintainable, and consistent
- Build and improve customer-facing product surfaces across the Alloy platform, helping shape frontend systems and experiences that are not only scalable for engineers, but genuinely useful and intuitive for the people using them
- Partner closely with engineers, designers, and product counterparts to turn broad needs into simple, durable solutions with company-wide impact
- Raise the quality bar for frontend engineering through thoughtful design, strong implementation, clear documentation, and pragmatic technical leadership
- Improve the developer experience by reducing friction in local development, testing, release workflows, observability, and day-to-day engineering workflows
- Identify opportunities to modernize how we build, ship, and maintain frontend software, including responsible use of AI and agentic engineering tools where they increase quality and leverage
- Contribute as a senior engineer on a growing team: driving technical decisions, mentoring others, and helping shape the team’s direction as its charter expands
Benefits
- Unlimited PTO and flexible work policy
- Employee stock options
- Medical, dental, vision plans with HSA (monthly employer contribution) and FSA options
