Principal Software Engineer

We're truly grateful that so many people have Foundant on their radar — it means a lot that our work resonates with others. That said, due to the high volume of direct messages and emails we receive, cold outreach isn't the preferred way to be considered for a role, and we're not able to prioritize applications submitted this way.

About Foundant
At Foundant, we build mission-critical software for the social good ecosystem — helping foundations, grantmakers, nonprofits, and community organizations streamline their work, strengthen relationships, and maximize their impact. We serve the giving community worldwide with a comprehensive suite of solutions spanning grant management, community foundation software, and giving analytics.

We're a unified company shaped by strong roots across our product portfolio, and we operate with intention and purpose. Our team of ~350 people across six countries is connected by a shared North Star: to be the trusted partner and strategic advisor to the communities we serve.

Where You’ll Work:

As a remote-first workplace, we believe in offering flexibility and the freedom to work where it suits you best, while staying connected through technology. Our global network of talent is supported by physical office hubs and virtual collaboration, fostering a dynamic environment where innovation and growth thrive.

With office locations in Bozeman, MT, Toronto, Canada, and Dublin, Ireland, you'll be part of a globally connected team. Whether you're working remotely or from one of our office locations, you'll be contributing to a vibrant, collaborative culture focused on driving meaningful impact across the world.

What You’ll Do:

This role has two centers of gravity. You'll be dispatched into product teams to help design and implement solutions, solve hard engineering problems, and you'll own the shared services that every one of our products depends on.

You'll embed with product teams across our portfolio to take on their hardest technical problems, and you'll deliver 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 own oversight of changes to Foundant's shared services, along with their ongoing production care and feeding.

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's code.

You'll lead solution design on significant initiatives, bringing a small group of engineers along with clear, well-articulated direction rather than handing down a finished answer.

You'll set the standard for how AI-assisted development is used well at Foundant — where generation accelerates the work, where it needs a harder look, and how teams around you can raise their own bar.

You'll move fluidly across products, domains, and service boundaries, leaving each team better equipped than you found it.

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.

Demonstrated mastery of architectural patterns and the judgment to know which apply in a given context, at both the application and service level.

Deep expertise in one or two of the technologies in our stack, with the ability to become productive in the others. Our environment includes Java, C#, Type Script, Node.js, React, Python, and Flutter.

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.

Experience diagnosing complex issues that span multiple components, services, or teams.

Must be legally eligible to work in the United States or Canada.
