Software Engineer, Applied AI

Your mission

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 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.
