Staff Software Development Engineer

About the role
You'll be a technical leader in Altium's Engineering Experience Team, working across everything external developers, partners and enterprise customers use to build on Altium. That includes the public API, SDKs and developer tools, the Developer Center, and the platform capabilities that let Professional Services deliver bespoke solutions for our largest customers.
You'll help take the Developer Center to public release, then shape how the platform grows. You'll set technical direction, make the hard design calls, and work through many teams you don't manage to get things done. It's a broad role, so prioritising well, and knowing what to build once for everyone, matters as much as building it.
Who we're looking for
- 8+ years of professional software engineering experience, with strong C# / .NET.
- A track record of technical leadership at staff level or equivalent: setting direction, making design decisions with long-term impact, and driving changes across teams you don't manage.
- Deep experience designing and evolving APIs used by external developers, including versioning, backward compatibility and deprecation. GraphQL experience is strongly preferred.
- Experience building developer-facing products, such as SDKs, developer tools, platforms or developer portals.
- Experience with enterprise software, ideally including identity and SSO, integrations, or on-prem deployments.
- A product mindset: you look for the pattern behind a request and solve it once for everyone.
- Clear communication with colleagues, partners and customers, including user-facing documentation.
- A genuine interest in teaching and sharing expertise.
- Hands-on use of AI coding tools, with the discipline to test, review and challenge their output.
Nice to have
- GraphQL federation or distributed schema design, and domain-driven design.
- Solid Python and/or TypeScript, and package publishing through NuGet, npm or PyPI.
- Open-source maintainer or contributor experience.
- Enterprise identity in depth (SAML, OIDC, OAuth), PLM integrations (such as PTC Windchill, Siemens Teamcenter, Aras Innovator, or PTC Arena), or software licensing.
- Experience building MCP servers, LLM-based tools, or agentic systems.
- Experience with AWS, Azure or GCP, and with Kubernetes.
- Experience with EDA or PCB design tools, Altium products, or the electronics industry.
Why the Engineering Experience team?
We're opening Altium's platform to developers, partners and AI agents. Through the Altium Developer Center, engineers can build on Altium 365, Altium Designer and Octopart using our GraphQL APIs, SDKs, developer tools and MCP servers. After a closed beta this year, we're preparing for public release.
We work in two closely linked areas:
Enterprise & Partners. Covers the Developer Center, the public API, SDKs and developer tools, open-source work, and integrations for our most complex enterprise customers, including the on-prem Altium Enterprise Server.
MCP & Agentic Platform. Covers Platform MCP for Altium 365 and Altium Enterprise Server, the MCP gateway, and our wider agentic platform.
Collaborating with our Enterprise Professional Services, we know how enterprise customers actually integrate with Altium, what goes wrong, and what they need. Our job now is to turn that knowledge into platform capabilities, tools and documentation that scale. That includes giving customers directly or via Professional Services the APIs, development infrastructure and knowledge they need to build and deliver bespoke solutions themselves.
We work closely with the internal API, infrastructure and product backend teams, and with Professional Services as a key partner. We build for everyone from individual developers learning through our forums to large enterprises running critical integrations. For our largest enterprise customers, Professional Services owns the engagement, and we support them as the platform team behind it. It's an exciting moment to join: the direction is clear, and there's a lot of shaping still to do.
AI is at the heart of what we build, not just how we build it. Through our MCP servers and agentic platform, we're creating AI-powered tools that let customers, partners and developers bring their own AI agents to Altium's design data and workflows. We also use AI tools every day to build faster, and we hold a high bar on reviewing and verifying what they produce.
You can expect deep technical challenges, high autonomy, a supportive and collaborative team, and real influence over the direction of the platform. You'll represent Altium's platform to colleagues, partners and customers, including some of the most influential technology companies in the world.
