[Hiring] Senior Software Engineer @SureCost

Role Description

The Senior Software Engineer builds, maintains, and improves the backend services, APIs, and third-party integrations that power SureCost’s pharmacy purchasing and inventory platform, which over 1,600 pharmacies use every day. The role writes production software with fully agentic AI development workflows. AI agents (Claude Code or equivalent) are the main environment for writing, testing, and running code. The work is backend focused and centered on .NET, within a full-stack ownership model. The engineer owns features end to end: the API contract, the service logic, the data layer, any external integrations, the supporting UI where needed, deployment, and production support. They work in a cross-functional pod with other senior engineers and QA.

Qualifications

• 8+ years of professional software engineering experience, with substantial production backend work in C# / .NET.
• Hands-on experience building and supporting production integrations with third-party platforms.
• Demonstrated experience shipping production code through fully agentic AI development tools (Claude Code, Codex CLI, Cursor agent mode, or equivalent).
• Strong proficiency in ASP.NET Core, RESTful API design, asynchronous programming, and dependency injection, plus an ORM such as Entity Framework Core and/or Dapper.
• Solid relational database skills (SQL Server and/or PostgreSQL): schema design, query optimization, and migrations.
• Working proficiency in React and TypeScript, enough to build and modify front-end features as part of full-stack delivery.
• Strong problem-solving skills: able to read unfamiliar codebases quickly, debug across layers (API, data, external systems, UI), and make sound technical decisions under time pressure.
• Working fluency in at least one major cloud platform (AWS preferred; GCP or Azure acceptable).
• Demonstrated end-to-end ownership of production software, including post-release support.

Requirements

• Design, develop, and maintain backend services and RESTful APIs in C# / .NET (ASP.NET Core).
• Build and maintain integrations with third-party systems, such as accounting platforms, ERP, EDI, and vendor APIs.
• Design data models and write efficient, well-tested data access against relational databases.
• Direct agentic AI development workflows to write, test, refactor, and document code.
• Own delivered work end-to-end: design, implementation, automated tests, deployment, monitoring, and fixing production issues.
• Build and maintain automated test coverage (unit, integration, and contract tests).
• Work with the pod on API contracts and build or modify React / TypeScript front-end code when needed.
• Take part in sprint planning, estimation, code review, and the pod’s operational cadence.
• Contribute to shared libraries, integration patterns, and platform foundations.

Benefits

• Independently delivers the pod’s committed backend and integration work through the release gate, sprint over sprint.
• Uses the team’s agentic development pipelines fluently, and agent-authored test coverage ships with every feature.
• Owns at least one production service or integration surface with no unresolved escaped defects attributable to delivered work.

Company Description

Reports to the Director of Engineering (career line) and takes technical direction from the pod lead. Works daily with pod engineers, QA, the product owner, and contractor teammates.
