Description

  • Design and build backend services and APIs that AI agents can invoke to query data, trigger workflows, and interact with internal and external systems.
  • Integrate agent tooling with LanguageWire’s internal platform APIs, third-party services, and databases.
  • Define clear tool schemas and contracts, including function schemas, OpenAPI specifications, and MCP server definitions.
  • Build end-to-end agentic workflows that automate business cases across operations, finance, sales, and project management.
  • Own services end-to-end, including architecture, coding, deployment, monitoring, and maintenance.
  • Extend existing .NET microservices and data layers to expose capabilities needed by AI tools.
  • Set up and improve CI/CD pipelines to support reliable and frequent delivery.
  • Apply DevOps and operational excellence practices to make tools observable, resilient, and secure.
  • Collaborate with product managers, domain experts, and engineers to identify automation opportunities and shape AI-powered solutions.
  • Share knowledge with the team and help define how the company builds AI-powered products.

Requirements

  • Strong backend experience with C#, .NET Core / .NET 6+, ASP.NET Web API, and microservices.
  • Solid experience with relational databases such as MSSQL and/or PostgreSQL, including query design, schema design, and performance tuning.
  • Proven ability to design and build REST APIs and integrate with third-party services and webhooks.
  • Familiarity with async programming, event-driven architecture, and message queues such as Azure Service Bus or RabbitMQ.
  • Some frontend exposure with Vue.js and/or TypeScript is beneficial, though the role is primarily backend-focused.
  • Practical understanding of LLM APIs such as Anthropic, OpenAI, and Azure OpenAI, including calling them and handling responses.
  • Experience designing or consuming tool/function calling schemas and defining what an agent can invoke.
  • Familiarity with MCP (Model Context Protocol) or similar agent-tool integration patterns, or eagerness to learn.
  • Understanding of security and authentication for exposed tool APIs, including OAuth 2.0, API keys, rate limiting, and input validation.
  • Observability mindset with logging, tracing, and monitoring for tool invocations and agent interactions.
  • Product mindset with a focus on solving real business problems.
  • Comfort working with non-technical domain experts to identify automation opportunities and translate them into technical solutions.
  • Strong communication skills with fluent English.
  • Agile, collaborative, and constructive working style.
  • Hands-on DevOps experience with CI/CD pipelines, Docker, Kubernetes, and cloud platforms, with Azure preferred.
  • Experience designing agentic workflows, including chaining tool calls, handling state, and structuring multi-step automated processes.
  • Familiarity with agent orchestration frameworks such as LangChain, Semantic Kernel, AutoGen, or similar.
  • Experience with event-driven or workflow automation platforms such as Azure Logic Apps, n8n, or Temporal.
  • Knowledge of prompt chaining patterns and reliable, deterministic tool-calling behavior in LLM pipelines.

Benefits

  • Full-time FlexiWire@home option for remote work.
  • Flexible access to the office for collaboration and connection with colleagues.
  • Private health insurance.
  • Internal development opportunities and ongoing support from a People Partner.
  • Inclusive and fun company culture with regular social get-togethers such as Friday bars and seasonal parties.
  • Modern city-center offices with a rooftop terrace.
  • Dog-friendly workplace.
  • Access to organic fruits, nuts, biscuits, and coffee, plus a social area and game room.
