Building the Future of Open Finance

Payward, the parent company behind Kraken and other financial infrastructure platforms, has spent 15 years building one of the most modern and globally accessible financial infrastructure platforms in the industry, designed to advance an open, global financial system.

The Team

Founded in 2011, Kraken is one of the world's longest-standing crypto platforms, trusted by over 10 million individuals and institutions globally. It offers spot trading, margin, futures, staking, and OTC services for both individual and institutional clients.

The Dev Platform team builds the internal platform that Kraken's engineers use to build, ship, and run software. Within Dev Platform, the AI Gateway is Kraken's company-wide LLM gateway: a single, governed entry point that gives teams self-service access to leading models from providers such as Anthropic, OpenAI, and Google. It provides visibility into usage and cost, configurable budgets and rate limits, and routing across models and providers for efficiency and resilience.

The Opportunity

• Build and extend the AI Gateway: new model and provider integrations, routing policies, budgets, rate limits, and usage and cost reporting.
• Design the APIs, SDKs, and self-service tooling that enable engineers across Kraken to onboard to the gateway quickly and safely.
• Help teams migrate their LLM workloads onto the gateway with minimal disruption.
• Implement access control, key management, and audit logging in partnership with Security.
• Instrument the gateway so teams can see latency, errors, token usage, and cost for their own workloads.
• Own features end-to-end, from design through production, and keep the service reliable alongside SRE.
• Support internal users with clear documentation, debugging help, and a tight feedback loop that shapes the roadmap.
• Contribute to code review, design documents, and engineering practices across Dev Platform.

Skills You Should HODL

• Solid experience as a backend or platform software engineer building and operating APIs and distributed services in production.
• Strong skills in a backend language such as Rust, Python, or TypeScript, with a habit of writing well-tested, maintainable code.
• Working knowledge of how LLM APIs behave: authentication, streaming responses, token accounting, rate limits, and provider failure modes.
• Experience with observability, CI/CD, and containers, and comfort with Kubernetes and a major cloud provider.
• Ability to design clean, well-documented APIs for internal customers and to weigh their feedback.
• Clear written and verbal communication, and the ownership to carry work from idea to production.

Nice to Haves

• Experience with API gateways, proxies, or traffic management.
• Experience building LLM-powered systems, including routing, caching, evaluation, or cost controls.
• Familiarity with authentication and authorization patterns (OAuth, OIDC, RBAC).
• Contributions to open-source infrastructure or developer-platform projects.
