Learn more at Proper.ai We are looking for a Senior Software Engineer with strong backend and systems fundamentals to help own the core of our platform: the services, data models, and automations behind workflow and productivity tooling for B2B accounting operations. This is a depth role, not a breadth role. The work is logic-heavy — multi-service data flows, third-party platform integrations, and document-processing pipelines where correctness matters more than surface area. The engineer will be a technical counterpart to the Tech Lead on architecture, and will take ownership of our AI-backed document processing service. The ideal candidate is language-agnostic in outlook but deep in practice: comfortable moving between Go, Python, and TypeScript, and able to build a real working model of an unfamiliar system before changing it. Proper is proud to be an equal opportunity employer committed to creating a diverse environment to work by offering the same opportunities to all applicants regardless of gender, sexual orientation, race, color, religion, disability, national origins, marital status, or other characteristics. We base our talent search exclusively on competencies, abilities and potential.
