This is a foundational role - you'll be the first engineering hire, responsible for designing and building an entire suite of financial service applications as a team of one to start . You'll create end-to-end experiences across multiple product lines - from front-end UI to back-end services - and lay the technical and user experience foundation that future engineers will build on. We're moving fast, and you'll need to be comfortable working independently, making key decisions, and shipping quickly to meet short, business-critical deadlines. This role is perfect for someone who thrives in ambiguity, loves wearing multiple hats, and is driven by the challenge of turning complex problems into simple, intuitive experiences. The right person will have experience working in a role like this previously. What You'll Do Own and execute the full development lifecycle for multiple financial product experiences - design, front-end, back-end, deployment, and iteration. Translate product ideas and business needs into user-friendly, production-ready applications. Craft beautiful, responsive UIs with a strong emphasis on usability and simplicity. Build and maintain backend services, APIs, and integrations with financial systems and third-party service providers Operate autonomously, prioritize effectively, and deliver high-quality work on short timelines. Establish scalable technical patterns and UI foundations for future engineers to build on. Collaborate closely with stakeholders to iterate quickly based on feedback and real user needs. Balance speed with maintainability and long-term architectural vision. Frontend: React (or similar), TypeScript Backend: C# Core, Python, or Java (flexible) Cloud & DevOps: Azure, Docker, GitHub Actions, Kubernetes (as needed) Data: SQL, REST/GraphQL APIs What We're Looking For 10+ years of hands-on software engineering experience, with at least 3 years at a principal or staff level. Proven ability to design and implement entire applications solo - from UI to infrastructure. Deep experience building thoughtful, elegant, and accessible user interfaces. Strong understanding of the full stack, with the ability to make high-level architecture decisions and execute them. Experience in financial services or similarly regulated environments is a plus. Highly self-motivated, fast-moving, and comfortable navigating ambiguity. Excellent communication skills and a user-first, product-minded approach. Nice to Have Experience with financial products (e.g., investing, banking, estate planning, insurance). Familiarity with security best practices for sensitive financial data. Background in design systems or UX research. Why Join Us? Greenfield Opportunity: Build the entire engineering foundation from the ground up. End-to-End Ownership: Your work will shape the experience of every user and define how we build going forward. Mission-Driven: We're creating financial services that are simple, transparent, and designed to help people - and we're doing it with design at the core.
