Payward - the parent company behind Kraken, NinjaTrader, Breakout, xStocks, Payward Services and CF Benchmarks - has spent the last 15 years building one of the most modern and globally accessible financial infrastructure platforms in the industry, built to advance an open, global financial system.
The TeamFounded in 2011, Kraken is one of the world's longest-standing crypto platforms, trusted by over 10 million individuals and institutions across the globe. It offers spot trading, margin, futures, staking, and OTC services, with products built for both individual investors and institutional clients.
Kraken's engineers build a lot of software. Developer Platform AI builds the AI systems they use to do it: agents that write and review code, simple access to the best models in the tools they already use, and the infrastructure that connects AI to our internal systems.
This is a small team with a lot of reach. The tools you ship will change how engineers across Kraken work every day, and you'll see that happen directly. The work spans agent platforms, code review, LLM routing and cost controls, MCP integrations with tools like Slack, Jira and GitLab, and the security and observability that make all of it safe to run.
If you want to work on applied AI with real users from day one, this is that job.
Build the platform Kraken's agents run on: dynamic sandboxes, Slack workflows, approval gates, memory, and agents that can take real engineering work from start to finish
Build our code review agent so merge requests get fast, useful feedback, and human reviewers can spend their time on design, risk and judgment
Give engineers access to approved models in Claude Code, Cursor and Codex with no setup, so trying a new model takes seconds
Build the connections between AI and the tools engineers use every day, including Slack, Jira, GitLab and internal APIs
Route LLM requests to the right model for the job, balancing speed, quality and cost
Work with Security to build access control, audit logging, budgets and cost reporting into the platform
Own features end to end, from design through production, and keep them reliable alongside SRE
Stay close to the engineers using what you build, and use their feedback to decide what comes next
Solid experience building and running backend or platform services in production
Strong skills in Rust, Python, TypeScript or Go, with a habit of writing well-tested, maintainable code
Comfort with Kubernetes, CI/CD, observability and a major cloud provider
Good judgment about reliability, security and operational tradeoffs
The ability to lead a technical design, write it down clearly, and work with teams outside your own
Ownership: you can take something from idea to production and keep it working once it's there
Hands-on experience with LLM APIs: streaming, token accounting, rate limits, provider failure modes
Experience building agent systems, code review or static analysis tooling, sandboxed execution, or developer tools
Experience with API gateways, proxies or traffic management
Familiarity with OAuth, OIDC and role-based access control
Contributions to open-source infrastructure or developer-platform projects
