Senior Go Developer (AI / LLM Platforms)

About the Role

We are looking for a senior-level Go developer who can work independently, research solutions, and deliver production-grade systems using modern AI and LLM technologies. You will be involved in designing and building scalable services, integrating AI/LLM capabilities, and supporting end-to-end delivery — from discovery and prototyping to production operations. The role requires strong backend fundamentals, ownership mindset, and the ability to collaborate across teams globally.

What you will do (Responsibilities)

• Design, develop, and operate backend services for internal and external customers.

• Build scalable microservices in Go and ensure reliability, performance, and security in production.

• Integrate AI/LLM services (cloud or on-prem), including model serving APIs, orchestration, and monitoring.

• Collaborate in an international team: gather requirements, discuss ideas, share insights, and align on solutions.

• Contribute to architecture decisions: API design, data modeling, infrastructure patterns, and service boundaries.

• Support and extend existing Python components (maintenance, small feature development, integrations).

• Own delivery lifecycle: planning, implementation, testing, deployment, troubleshooting, and continuous improvements.

• Ensure high engineering standards: code reviews, CI/CD practices, observability, and documentation.

• Oversee and coordinate the research and development team assigned to the activity (task planning, technical guidance, progress tracking).

Key Requirements

• 7+ years of backend engineering experience; 4+ years of commercial experience with Go.

• Proven experience building and running microservices at scale in production environments.

• Strong hands-on background with Docker, Kubernetes, APIs, and databases (SQL/NoSQL).

• Working knowledge of Python (ready to maintain and extend Python code when required).

• Experience integrating AI/LLM services (cloud providers or on-prem solutions).

• Solid understanding of distributed systems: resiliency patterns, scaling, messaging, caching, and performance tuning.

• Ability to work independently with minimal supervision; strong ownership and accountability.

• Research-driven mindset with a strong delivery focus (able to evaluate options and implement the best approach).

• English proficiency sufficient for technical communication in an international team.

Nice to have

• Experience with LLM tooling (RAG pipelines, vector databases, embeddings, prompt orchestration).

• Familiarity with model observability and evaluation (latency, quality metrics, tracing).

• Experience with event-driven architectures (Kafka, RabbitMQ) and service meshes.

• Experience in telecom, enterprise platforms, or mission-critical systems.

We offer

• Opportunities for professional growth and career development in international projects.

• Medical insurance.

• Sports activities and corporate events.

• Friendly and supportive engineering culture with mentorship and knowledge sharing.

• Flexible working hours and modern office environment.

• Competitive compensation package, discussed individually with the successful candidate.
