Software Engineer

About the Role Join the engineering team at a construction technology and financial operations startup building backend systems that connect fragmented software platforms. You will help create reliable, scalable integrations that give customers a consistent way to work with data across modern and legacy systems. What You'll Do Design system-agnostic data models and features for integrations across many software platforms. Build secure, reliable connections to legacy and on-premise systems, including systems with limited or no modern APIs. Improve API performance and scalability through efficient data storage, retrieval, and caching. Develop testing approaches that identify integration edge cases across a broad range of endpoints. Build backend services and frontend applications that use and validate the team's APIs. Research each system's behavior and adapt integrations to its distinct technical requirements. Ship improvements frequently and incorporate customer feedback into product development. What We're Looking For One to six years of experience as a backend or full-stack software engineer, with the ability to work independently. An undergraduate degree in computer science and strong software engineering fundamentals. Familiarity with cloud infrastructure, including AWS; experience with Redis and PostgreSQL is relevant. Experience at a technology startup, or a clear interest in joining a fast-paced startup environment. Interest in backend and integration challenges, with willingness to focus primarily on non-AI engineering work. A record of ownership, self-motivation, collaboration, and sustained contributions in prior roles. Compensation & Benefits Base salary is $140,000 to $260,000 USD annually.
