If you are an innovative, curious, collaborative person who embraces challenges and wants to grow, learn and pursue outcomes with our prestigious financial clients, say Hello to SimCorp!\nAt its foundation, SimCorp is guided by our values - caring, customer success-driven, collaborative, curious, and courageous. Our people-centered organization focuses on skills development, relationship building, and client success. We take pride in cultivating an environment where all team members can grow, feel heard, valued, and empowered.\nIf you like\nwhat we’re saying, keep reading!\nWHY THIS ROLE IS IMPORTANT TO US\nAre you an expert engineer ready to build an internal AI agent that safely and reliably supports the software development lifecycle (SDLC) across a global fintech? At SimCorp, we develop products that power investment management and financial institutions worldwide - and we are investing heavily in AI to make our own engineering organization faster and better.\nYou will join the team developing our internal AI agent for the software development lifecycle: a production-grade product that helps engineers investigate code, analyze CI failures, review pull requests, work with backlog items, and automate recurring tasks through secure tools and agents. It is a real distributed product - agent runtime, enterprise integrations, sandboxed execution, and Azure operations - built and run end to end by this team. The agent runs as a single always-on hosted service that engineers across the organization use concurrently.\nThis is a practical leadership role: you will combine deep technical expertise in .NET distributed systems and AI-agent engineering with mentoring, architectural ownership, and collaboration across international teams.\nWHAT YOU WILL BE RESPONSIBLE FOR\nAs a Software Engineer on this team, you will:\nEngineering and architecture\nDeeply participate in technical design, development, and operation of the product. \nEvolve the AI-agent runtime: how agents plan, use tools, manage context, and reliably recover state. \nDesign secure, resilient integrations with engineering systems (source control, CI/CD, work-item tracking, collaboration and documentation platforms) through typed connectors, and MCP tools. \nImprove the agent's secure execution environments: hosted Linux sandboxes and remote sessions that let the agent assist directly on a user's machine, with confirmation and audit models\nMaintain and extend the Blazor Web Assembly frontend that engineers use to work with the agent every day. \nOperations and quality\nOwn production reliability on Azure: telemetry, diagnostics, performance and cost monitoring, deployment pipelines, and operational documentation. \nWrite high-quality automated tests at unit, functional, integration, and acceptance levels, and design for testability. \nLeadership and collaboration\nMentor and coach engineers, and review code and architectural changes with an emphasis on correctness, security, and long-term product evolution\nRepresent the team in technical forums and contribute to cross-team knowledge exchange on AI engineering practices. \nMost importantly, you can see yourself contributing and thriving in the position described above. We expect you to be strong in several of the following and interested in learning the rest:\nBachelor's or master's degree in computer science, Engineering, Mathematics, or a related field. \n 5+ years of software engineering experience with advanced C#/.NET backend skills\nDeep distributed-systems judgment: asynchronous processing, concurrency, cancellation, retries, idempotency, and state recovery\nExperience building AI/LLM applications beyond simple prompt calls: tool calling, agent orchestration, structured outputs, context management, and model-provider abstraction (e.g., Azure OpenAI). \nAt least 1 year of practical, daily experience working with AI coding agents such as Claude Code or Codex\nExperience with open-source agents (e.g., OpenCode, Hermes, OpenClaw, or similar) and curiosity about how they work under the hood. \nMotivation to work in the AI space and the flexibility to try new technologies: you stay on top of market trends and bring the ecosystem's best practices - better memory, context management, and agent autonomy - into the product\nSolid experience with ASP.NET Core, relational persistence (PostgreSQL/EF Core preferred), and designing external-facing APIs with authentication, authorization, rate limiting, and resilience policies. \nCloud engineering experience on Azure. \nSolid working knowledge of Linux: shell, processes, networking, and filesystems, and comfort debugging inside containerized environments. \nPractical experience with Docker and container isolation is highly recommended; familiarity with sandboxing technologies such as Sysbox, gVisor, or microVM-based isolation (e.g., Firecracker) is a strong advantage\nAbility to reason about security boundaries, secrets, RBAC, auditability, and safe execution of side-effecting operations. \nFrontend experience with Blazor or a modern SPA framework\nExperience with Windows automation which powers the agent's ability to assist on user machines\nAbility to lead or mentor engineers and make technical decisions\nEffective English communication skills, both written and spoken\nBENEFITS\nAttractive salary, bonus scheme, and pension are essential for any work agreement. However, in SimCorp we believe we can offer more. Therefore, in addition to the traditional benefit scheme, we provide a good work-life balance: flexible working hours and a hybrid model. Simcorp follows a global hybrid policy, asking employees to work from the office two days each week while allowing remote work on other days.\nSimcorp does offer opportunities for professional development: there is never just only one route - we offer an individual approach to professional development to support the direction you want to take.\nNEXT STEPS\nPlease send us your application in English via our career site as soon as possible, we process incoming applications continually.
