Design and build the software that turns large language models into reliable, production-grade
products. You'll work across the full stack — backend services, AI tooling, and user-facing interfaces
— shipping features that let AI agents reason over data and act safely on behalf of users.
Responsibilities & Duties
- Implement and design features: Develop high-quality software components — both conventional services
and AI/LLM-powered capabilities — that align with established architectural patterns and business
requirements.
- Task decomposition: Break down assigned features into manageable technical tasks and provide reliable
estimates for delivery timelines.
- Code ownership: Write, maintain, and optimize clean, modular code, ensuring performance, scalability,
and (for AI features) cost and context efficiency are considered during implementation.
- Quality assurance: Participate actively in code reviews, provide constructive feedback to peers, and
adhere to defined coding standards and quality protocols. Evaluate AI features for correctness, safety,
and regressions.
- Cross-functional collaboration: Coordinate with colleagues to clarify requirements and ensure
seamless integration of new features.
- Knowledge sharing: Contribute to internal documentation to promote team-wide understanding of the
codebase and AI system behavior.
- Process contribution: Identify opportunities for technical-debt reduction and suggest improvements to
the development workflow or toolset to increase efficiency.

Your mission
Your profile
Must have
- Strong experience in at least one backend language and ecosystem (e.g. Python, TypeScript, Go, Java,
or C#/.NET).
- Deep understanding of software design fundamentals — OOP, SOLID, and separation of concerns.
- Expertise in developing RESTful web services and web applications.
- Solid knowledge of SQL and database/data modeling.
- Comprehensive knowledge of version control systems, particularly Git.
- Experience writing automated tests (unit and integration).
- Communication skills, with the ability to synchronize effectively within a team.
- Proven experience working with scalable, high-performance systems.
AI / ML engineering
- Hands-on experience building LLM-powered applications — prompt design, tool/function calling,
structured outputs, or RAG.
- Understanding of how to make AI features reliable and evaluable — handling non-determinism, context
limits, latency, and cost.
- Familiarity with agent patterns and orchestrating multi-step AI workflows.
Nice to have
- Knowledge and experience with cloud technologies (Azure, AWS, or GCP); infrastructure-as-code (Bicep,
Terraform) a plus.
- Experience with vector databases, embeddings, or retrieval pipelines.
- Experience with model evaluation / observability tooling (e.g. tracing, prompt management, eval
frameworks).
- Understanding of cyber security essentials (auth, secrets management, least-privilege access).
- Experience developing and maintaining microservices.
- Frontend experience (e.g. React/TypeScript) for building AI-driven user interfaces.
