About Scalekit
Scalekit is building the authentication stack for AI applications. We started by solving enterprise-grade auth for B2B SaaS - features like SSO, SCIM provisioning, multi-tenant orgs, and admin portals. Now, as AI adoption accelerates, authentication has to work not just for human users but also for AI agents.
- Inbound auth for MCP servers using OAuth 2.1, PKCE, and dynamic client registration.
- Outbound actions for AI agents through token vaults and scoped access to third-party apps.
We’re backed by top investors and a strong network of engineering leaders. At Scalekit, we focus on solving hard authentication problems while obsessing over delivering great developer experiences.
Why This Role Matters
We’re looking for a Software Developer (1-3 years of experience) to join our focused, high-impact team in San Francisco. You’ll work directly with the founders and core engineers to:
- Build reference apps, integrations, and proofs-of-concept
- Create examples and quickstarts that make Scalekit simple and intuitive for other developers
- Bring real-world developer feedback into our product and docs.
This is a unique opportunity to learn fast, ship quickly, and directly shape how developers adopt authentication in AI-driven products.
What you’ll do
1) Build reference apps and POCs
- Create small, runnable projects in Python, Node.js, and Next.js that demonstrate key auth flows (SSO, passwordless logins, agent auth, and MCP integration).
- Publish quickstart repos, snippets, and scripts that other developers can copy and adapt.
2) Help with real integrations
- Work alongside the team and customers during pilots to reproduce and fix issues.
- Patch small utilities or examples that reduce friction, and document what you learned.
3) Feed learnings back into the product
- Spot recurring issues and suggest SDK improvements or validation checks.
- Share feedback with the core team on how onboarding and workflows could be smoother.
4) Engage with the developer ecosystem
- Attend local developer events to hear what problems others face and bring insights back to the team
- Participate in GitHub discussions when you can contribute code or fixes.
Challenges You’ll Help Solve
- Make it simple for developers to plug Scalekit auth into their SaaS and AI apps
- Create “aha!” moments - shorten the path from first test to production.
- Build reusable code and examples that other developers trust and love.
What we’re looking for
- Builder at heart: You explore new SDKs, APIs, and stacks, figure things out quickly, and enjoy experimenting
- Hands-on coder: Proficient in at least one of Python, Node.js, or Next.js, with the ability to learn from others as needed
- Empathy for developers: You care about the small details that make (or break) a great developer experience, from error messages to onboarding guides
- Self-starter: You take open-ended problems, build proofs-of-concept, and ship usable solutions
- Collaborative Style: You’re excited to explain your solutions, write clean GitHub repos, and contribute to the developer community
- Comfort with startup pace: adaptable, willing to wear multiple hats, and thrive in an environment where priorities can shift
Bonus if you have
- Exposure to authentication/identity protocols (OAuth, OIDC, SAML, SCIM)
- Experience with IdPs like Okta, Entra ID, or Google
- Familiarity with cloud platforms (GCP or AWS)
- Prior startup or open-source contributions.
Why you’ll love working here
- Work side-by-side with the founders, shipping production-ready code from day one
- Directly shape how authentication works for the next wave of AI and SaaS applications
- Join a team that values curiosity, speed, and craftsmanship and where your contributions have immediate impact
- Backed by top investors and advisors in AI and infrastructure.
