Staff Software Engineer, C/C++ (Linux)

Job summary

We are looking for a Staff Software Engineer to build and lead work on the Linux server applications behind our pharmacy software. You will write C and C++ most weeks in a mature codebase of about 2 million lines, and you will lead projects and code reviews across the team.

This is a hands-on individual contributor role, not people management. Our roadmap includes a new web version of Rx30, new integrations, and moving e-prescribing and claims adjudication into central services. You will help shape how those get built and raise the bar for engineering across the team.

Healthcare experience is a plus but not required; we will teach you the domain.

Essential duties and responsibilities

Technical leadership

• Lead projects from design through release: set technical direction, break down work, size it, and keep it moving across engineering and QA.
• Lead code reviews and set the standard for C/C++ quality, safety and performance on the team.
• Mentor engineers through reviews, pairing and design discussions.
• Contribute to architecture decisions as we move shared functions out of Rx30 into central services.

Software development

• Design, build and maintain C and C++ applications and services on Linux.
• Work confidently in a large, long-lived codebase: read and change code you didn’t write, refactor carefully, and keep it maintainable.
• Build networked services using sockets and TCP, and integrations with outside partners and systems.
• Diagnose and fix production problems: crashes, memory leaks, threading bugs and performance issues.

Testing and quality

• Write unit, integration and automated tests for positive and negative cases, and coach others on test strategy.
• Work with QA to plan regression and performance testing for each project.

Operations

• Administer and troubleshoot the Linux environments our software runs in.
• Add the logging, monitoring and metrics that keep services dependable, and help improve build and deployment automation.

Security and compliance

• Write secure code with a security-first mindset, including correct handling and protection of PHI and PII.
• Identify and reduce risks through secure coding practices and threat modeling.

Requirements and design

• Work with product and business stakeholders to turn business needs into clear technical stories and designs.
• Explain complex technical issues to non-technical audiences.

Requirements

• 8+ years of professional C and C++ development of applications and services on Linux, including recent hands-on work in your current or most recent role.
• Hands-on Linux administration: configuring services, managing users and permissions, reading logs, and troubleshooting servers from the command line.
• Strong network programming: sockets, TCP/IP, and building and debugging client/server applications.
• Experience working in a large, long-lived codebase (hundreds of thousands to millions of lines) with many contributors.
• Skill with Linux debugging and analysis tools such as gdb, Valgrind or sanitizers, strace, and tcpdump.
• Experience leading technical projects and code reviews as an individual contributor, and mentoring other engineers.
• Solid grasp of design patterns, software architecture and multithreaded programming.
• Clear communication with both technical and non-technical stakeholders.

This role is not a fit for experience that is mainly embedded, firmware, microcontroller or device-driver development.

Nice to have

• Healthcare or pharmacy software experience, especially handling PHI/PII under HIPAA.
• Familiarity with pharmacy claims and adjudication, e-prescribing, NCPDP standards, or long-term care pharmacy.
• Experience with relational databases, web services and integrating with outside partners.
• Experience with CI/CD pipelines, containers or infrastructure as code.

Education and experience

• 10+ years of professional software development experience.
• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, Information Systems or IT, or equivalent work experience.
