Principal Software Engineer

What You’ll Do:

• You'll be part of Foundant’s product engineering team responsible for development activities along with their ongoing production environments care and feeding to take on their hardest technical problems, and you’ll deliver high-quality working code — not just direction. This is a hands-on role at every level of seniority it carries.
• You'll own architectural decisions at both the application and service level, making calls that hold up under real production load and remain understandable to the engineers who inherit them.
• You'll diagnose systemic and architectural issues that cross component and service boundaries, including the ambiguous ones where the cause isn't in any single team code.
• You’ll see the big picture and work proactively to resolve integration issues or coordinate across team boundaries.
• You’ll put AI-assisted development and agentic tooling to work in your daily engineering, shortening the path from idea to production-ready code and getting valuable improvements into clients’ hands sooner.
• Other duties as assigned.

What You’ll Need:

• 12+ years of professional software engineering experience, including significant time at a principal, staff, or equivalent senior individual contributor level as a hands-on developer.
• Demonstrated mastery of architectural patterns and the judgment to know which apply in a given context, at both the application and service level.
• Proven expertise in Java, Spring Boot, TypeScript, Node.js, and React, with a track record of building and shipping production software.
• Extensive full-stack development experience building scalable RESTful applications with React and Java/Spring Boot backend.
• Advanced proficiency working with large scale relational database management systems (RDBMS).
• Experience working with analytical systems and databases processing large volume of data.
• Proficient with AI assisted development practices and tooling.
• Proven experience developing cloud-based SaaS applications; experience working with AWS is highly desirable.
• Proven experience owning production services, including reliability, performance, and incident response.
• Professional experience using AI-assisted development tools in production work. Foundant uses Claude Code; deep expertise with a comparable tool is acceptable.
• Extensive experience diagnosing and debugging complex technical issues across multiple components and services, including the use of debugging and profiling tools.
• Must be legally eligible to work in the United States.

What You’ll Bring to our Team Dynamics:

• Adaptive Achievement: Moves between unfamiliar codebases, domains, and problem spaces without losing momentum, and delivers high-quality solutions under shifting priorities and incomplete context.
• Productive Collaboration: Leads engineers through complex initiatives by influence rather than authority — entering a team as a guest, earning trust quickly, and articulating direction clearly enough that the team can carry it forward without you.
• Service Orientation: Treats internal engineering teams as clients, and understands that the reliability of a shared service is ultimately felt by the foundations and nonprofits depending on our software to do their work.
• Business Insight: Weighs the blast radius of shared-service decisions across every product and client, balancing technical elegance against what actually advances the business and the communities we serve.
• Active Learning: Builds working depth in unfamiliar stacks quickly, and applies rigorous judgment to AI-generated code — knowing when to lean on it, when to scrutinize it, and how to help colleagues do the same.
