Senior Full-Stack Engineer (Backend Leaning)

We are seeking an experienced full-stack engineer with strong backend expertise to build and scale the core products that power modern procurement and sourcing operations. You will develop critical workflows, supplier bidding and award capabilities, and integrations connecting enterprise procurement platforms and ERP systems. Working closely with product managers, designers, frontend engineers, and QA, you will own features from domain modeling and APIs through production delivery. The role offers exposure to evolving product areas, requiring adaptability, technical judgment, and the ability to quickly understand complex business domains. You will also use AI coding agents as part of your daily workflow while maintaining high standards for architecture, code quality, and reliability. This is an opportunity to influence engineering practices, mentor peers, and help shape how AI transforms software development in a growing technology environment.

• Proven experience delivering production software across the full stack, with substantial depth in backend engineering.

• Strong fundamentals in system design, architecture, interface design, type safety, and effective testing practices.

• Professional experience with at least one statically typed programming language, such as Java, C#, Go, Kotlin, Scala, or Rust.

• Experience working with TypeScript and Python.

• Regular, hands-on use of AI coding tools or agents, such as Claude Code, Cursor, Codex, or GitHub Copilot agent mode.

• Strong judgment and discipline when reviewing, correcting, testing, and maintaining AI-generated code.

• Ability to quickly understand unfamiliar business domains, ask insightful questions, and identify key technical and operational constraints.

• Excellent written communication skills, including experience producing design documents, clear pull request descriptions, and technical decision records.

• Ability to work effectively in an asynchronous, documentation-driven engineering environment.

• Collaborative mindset, adaptability, and willingness to take ownership of outcomes beyond assigned tasks.

• Experience with procurement, ERP, or B2B commerce platforms such as Coupa, SAP Ariba, Oracle, or NetSuite is a plus.

• Familiarity with event-driven systems, data pipelines, Kafka, change data capture, or PostgreSQL at scale is an advantage.

• Experience in a startup or growth-stage company, particularly in roles involving end-to-end ownership, is beneficial.

• Open-source contributions, personal projects, or examples demonstrating effective use of AI coding agents are valued.

• Candidates must be based in the Boston area and able to work a hybrid schedule in Boston, Massachusetts.

• Candidates must be legally authorized to work in the United States; the job application asks whether sponsorship is currently or potentially required.
