Senior AI Developer
Added: 17.02.2026
Your responsibilities:
- Design, implement, and continuously optimize production-grade AI applications powered by LLMs, with a focus on accuracy, latency, and cost efficiency
- Architect and orchestrate end-to-end RAG pipelines — from document ingestion and chunking strategies to retrieval tuning and response evaluation — using frameworks such as LangChain, LlamaIndex, or DSPy
- Build robust, high-performance APIs and microservices using FastAPI, Django, or Flask, following REST and async design best practices
- Collaborate closely with backend and platform teams to seamlessly integrate AI services into scalable, cloud-native architectures on Azure
- Own the reliability, observability, and performance of AI services in production — including monitoring, alerting, and iterative improvements based on real usage data
- Write clean, modular, and well-tested code with a strong emphasis on reusability and maintainability; actively contribute to internal standards and documentation
- Design and manage containerized deployments using Docker and orchestration tools (Kubernetes, Docker Compose), ensuring reproducibility across environments
- Drive technical discussions, architecture decisions, and code reviews — sharing knowledge and raising the bar for the entire team
- Evaluate and integrate emerging AI tooling, models, and techniques to keep the team at the cutting edge
We are looking for you, if you have:
- Strong Python proficiency with deep, hands-on engineering skills — from clean API design to production-grade ML pipelines
- Solid experience designing and deploying RAG-based systems and LLM-powered applications, including retrieval tuning, chunking strategies, embedding selection, and response evaluation using frameworks like LangChain or Semantic Kernel
- Practical knowledge of OpenAI, Azure OpenAI, and Amazon Bedrock APIs, combined with the ability to evaluate and route across models depending on cost, latency, and task requirements
- Experience architecting multi-cloud AI solutions with a strong emphasis on Azure (Azure ML, Azure AI Foundry, ADF) and familiarity with AWS counterparts — able to reason about trade-offs across cloud providers
- Hands-on experience running and orchestrating self-hosted LLMs — including model selection, quantization, serving (e.g. NVIDIA Triton, BentoML, vLLM), and lifecycle management in GPU-accelerated environments
- Familiarity with Transformer architectures at a non-superficial level — understanding of attention mechanisms, fine-tuning strategies, ViT/BERT variants, and their practical implications for production deployments
- Experience building production-ready AI applications using AI templates and scaffolding patterns (LLM app templates, prompt management, LLMOps tooling like ZenML, MLflow, or ArgoCD) — not just prototypes, but observable, maintainable systems
- Backend development experience with FastAPI, Django, or Flask, including async patterns and integration with AI services in microservice architectures
- Solid grasp of Docker and container orchestration (Kubernetes, Docker Compose) for reproducible model and service deployments
We offer:
- Participation in interesting and demanding projects
- Flexible working hours
- A great, non-corporate atmosphere
- Stable employment conditions (contract of employment or B2B contract)
- Opportunities for development and promotion
- Attractive package of benefits
- Work model: remote or hybrid (2 days per week from the office)

Why is it worth joining TTMS?
Flexible working hours
Not everyone feels comfortable working the standard 9 a.m. to 5 p.m. hours. We have been successfully running projects for many years despite diversified work patterns.
Possibility of hybrid work
At TTMS, desk-to-desk work is what drives us, but we understand if someone prefers a hybrid model. We are equipped with all the necessary tools to work in a hybrid model.
Great, non-corporate atmosphere
Professionalism, attention to the quality of work and a friendly, informal atmosphere are not mutually exclusive. A flat structure and natural, friendly relationships create the basis for creativity and innovation.
Interesting, international projects
We create solutions for medium and large companies, we are present in Poland, Malaysia, Denmark, the UK, Switzerland, and India – the effects of your work will travel around the world. In TTMS you have an influence on the company’s success.
Together towards climate neutrality
We select subcontractors to minimize the carbon footprint, organize bush plantings, save peat bogs – all to achieve climate neutrality in 2025. We are glad that we are attracting more and more people who also care about sustainable development and environmental protection.
Friendly offices
Our offices are modern spaces that inspire employees and are environmentally friendly. Białystok is the kingdom of Marvel superheroes, Krakow is a soothing tropical forest, Wrocław is an art gallery, and the Lublin branch is a rock u0022hall of fameu0022.
