Software Engineer II FC Ops - Spreetail Inc.

Software Engineer III

Spreetail is looking for a Software Engineer III to join our team. Spreetail is a technology-driven e-commerce company that owns and operates the full retail supply chain (from manufacturer to customer doorstep). We move physical goods faster and more profitably than anyone else, powered by proprietary software, machine learning, and relentless operational focus.

• Design, build, and maintain the backend services that power Spreetail's fulfillment operations — inventory management, order processing, carrier integrations, and exception handling.
• Own the reliability and correctness of transactional systems that FC operations depend on every hour of every day.
• Lead technical design within your pod — driving architecture decisions, establishing patterns, and holding a high bar in code review.
• Identify and address systemic issues: performance bottlenecks, data consistency gaps, fragile integrations. Debug and resolve production issues quickly, with clear communication to stakeholders.
• Collaborate with product managers and FC operations teams to translate operational requirements into sound software design. Mentor SE II engineers and help raise the overall engineering quality of the team.

• 2-4 years of professional software development experience, with a strong backend focus. Deep proficiency in C# and the .NET ecosystem — you can design, build, and maintain production services independently and lead others doing the same.
• Familiarity with downstream ML pipelines (Python, dbt, Dagster) — you won't own them, but you'll work alongside them.
• SQL Server / PostgreSQL — operational and transactional data at the core of everything this team builds.
• AI tooling:
  Claude Code for development workflows.
• AWS (primary) —
