Pliant is a modular B2B payments platform that combines commercial card issuing, payment accounts, FX, and spend management in one system, adapting to existing setups rather than requiring customers to replace them. Fintechs and software platforms embed Pliant's payment infrastructure into their own products, from API-based Cards-as-a-Service to fully white-label solutions. A principal member of Visa and Mastercard, Pliant issues commercial cards in 13 currencies across 32 countries, under its own European e-money license and with licensed partners in the UK and US. We are hiring an Agentic Tooling Engineer (m/f/d) to join the Office of the CTO, reporting directly to the CTO and working closely with the Developer Experience team. This is not a prompt engineering role. Build and maintain the shared tooling of the framework: distribution and installation across agent tools, shared skills and agents, lints, eval runners, and the interfaces between harnesses. Run the feedback loops: collect friction from real use, fix the cause, and add a test so the failure does not return. Agentic tooling you built that other engineers use: skills, plugins, hooks,



subagents, MCP servers, or custom agents. ~ Experience with LLM evaluation and context engineering: evals for non-deterministic systems, reading failure traces, and understanding how the size, freshness, and consistency of context change what an agent does. ~7+ years of software engineering on production systems, including developer tooling or an internal platform with real users. Strong system design and a verification mindset: you know which controls must be deterministic and which can stay with a model. ~ Strong Python, git, and GitHub (Actions, rulesets, CODEOWNERS); you read Java and Kotlin with ease. ~ Precise technical writing and the ability to change how other engineers work without authority over them. ~ A plus if you have experience in a regulated environment such as payments or banking, a security engineering background, or an open-source project you maintained. Your choice of preferred OS, Windows or Mac Flexibility and possibility to work remotely
