Software Engineer(Amsterdam)

About the Role

Together.ai is looking for a Software Engineer to join the Identity & Collaboration team - a great role for a full-stack or backend engineer who wants to grow into functional programming and the identity space. As part of the Product Foundations engineering group, the Identity & Collaboration team owns authentication flows (including SSO and OAuth), organizations, projects, API keys, and the role-based access controls that enable secure collaboration at scale.

Every customer interaction with Together relies on the systems we build. Whether it's a researcher accessing their models, an enterprise team collaborating on a shared project, or a developer making an API call, we make authentication seamless and invisible for simple cases while providing robust, enterprise-grade capabilities for complex organizational structures. Our work directly enables Together's growth from individual users to large enterprise teams, and we're actively building the next generation of collaboration features that will unlock new ways for customers to work together securely and efficiently across all Together products.

Location: Hybrid in Amsterdam, NL or remote UK, Ireland & Germany

Full-time: This means 40 flexible hours, Monday through Friday.

You'll own well-defined features and small projects end-to-end, shipping work that lands in front of customers. You'll get guidance as you take on unfamiliar problem spaces, with plenty of room to grow toward more autonomy over time. We pair, review each other's code, and learn in the open - it's a strong environment to level up in.

Responsibilities

Build and ship features across the stack - TypeScript/Next.js on the frontend and Elixir/Phoenix services on the backend (which you can grow into)

Own well-defined pieces of work end-to-end, from implementation through testing and rollout

Contribute to our identity and access features: SSO, OAuth, organizations, projects, API keys, and role-based access control

Learn the Elixir/Erlang VM (BEAM) and how we run it in production

Participate meaningfully in code review and build your familiarity with our testing, tooling, and workflow

Surface blockers early and collaborate with the team to work through them

Work with relational (PostgreSQL) and non-relational (MongoDB) data

Requirements

Around 2–3 years of professional experience writing and shipping production code

Solid full-stack or backend engineering, especially with TypeScript (backend and/or frontend, for example with Next.js) - or another modern stack whose ideas you can bring across

Genuine enthusiasm to learn Elixir and Phoenix - production experience isn't required, and we'll support you in getting there

Writes clean, well-organized, well-tested code, and treats code review as a way the team grows together

Comfortable owning scoped work and surfacing blockers early

Curious, open to feedback, and willing to propose new approaches and make mistakes

Nice to Have

Interest in, or some exposure to, identity and access concepts - authentication, authorization, SSO, OAuth (this is a great team to learn them on)

Any exposure to functional programming (Elixir, Erlang, or similar)

If you don't meet 100% of the above, you should still consider applying. It's completely fine if you haven't used Elixir yet - if you're excited to learn it and have a passion for this kind of work, we want to talk to you.
