You will join a small engineering team at an important stage: our platform already supports thousands of renters, community organizations, and property partners, each with different needs and experiences. This is a hands-on role for an engineer who can independently take complex product work from design through release. You will build across the stack, including React-based web & mobile apps, GraphQL & MCP APIs, and org-wide data models. You will work closely with our technical lead, product, and design partners to make thoughtful tradeoffs and turn an ambitious roadmap into reliable, accessible software. What You Will Do * Design, build, test, release, and operate customer-facing product features across the frontends, APIs, and data layer. * Develop accessible, responsive web & mobile experiences using React and TypeScript. * Extend a GraphQL API and PostgreSQL database schemas to support evolving product needs and future growth. * Take ownership of defined product areas, making sound technical decisions and carrying work from initial scoping through production support. * Partner with product and design throughout discovery and development to understand user needs, explore solutions, clarify requirements, and balance delivery speed, technical quality, and long-term maintainability. * Create realistic estimates, surface delivery risks early, and communicate technical tradeoffs clearly to both technical and non-technical colleagues. * Strengthen testing, release, and documentation practices within the areas you own so the codebase is reliable and easier for future engineers to learn and extend. * Review code and contribute to shared application-development patterns and standards as the engineering team grows. * Work with the technical lead on technology upgrades, infrastructure decisions, security, and improvements to the broader engineering environment. * Protect sensitive client and partner information by embedding privacy and security into everyday engineering decisions.
