About Gapstars
Gapstars is a Netherlands-based software development services provider that builds remote, agile teams in Sri Lanka and Portugal for innovative tech companies. Today, we are home to 300+ TechStars and innovative minds, turning scalable software into performance products that shape the future. Our partners are highly ambitious tech companies that are looking to conquer their respective markets.
About the Role
We are looking for a pragmatic AI Engineer who can bridge solid software engineering practices with the fast-evolving landscape of applied AI. You’ll help design, build, and evaluate AI systems that are reliable, measurable, and actually useful, not just demos.
You'll contribute to our platform migration, and help raise the bar on how we build software, including bringing your AI-first working methods to the broader team. This is not a role for someone who wants to be told what to build. We expect seniors to reason about tradeoffs, challenge assumptions, and take end-to-end ownership of features and systems.
Responsibilities
Develop AI-powered applications from prototype to production using modern LLM frameworks and APIs
Design evals and metrics that measure real-world performance (accuracy, latency, UX quality, safety)
Build and optimize Retrieval-Augmented Generation (RAG) pipelines integrating vector databases and LLMs
Implement data pipelines, retraining workflows, and monitoring tools that keep models current and performant
Develop and implement context engineering strategies to improve output quality and control hallucination risks
Collaborate with product, platform, and infrastructure teams to understand business needs and build systems that scale and fail gracefully
Apply agentic AI patterns (tool use, planning, reflection loops) pragmatically, choosing the right level of complexity for each use case
Champion good engineering practices: code reviews, testing, observability, CI/CD, reproducibility
Ensure AI solutions meet security, compliance, and explainability standards
Share AI workflows, patterns, and tooling knowledge actively with the team. Run demos, document approaches, and help colleagues level up
Participate in agile ceremonies, sprint planning, and delivery processes
Take ownership of system reliability, performance, and operational concerns within your domain
5+ years of experience in Data Science or Software Engineering with 2+ years focused on AI Engineering and creating AI Agents
Experience with LLM APIs (OpenAI, Anthropic, or similar services)
Extensive knowledge of large language models (LLMs) and their underlying architectures, capabilities, and applications
Experience with GenAI frameworks and libraries (LangChain, LlamaIndex, Haystack, or Hugging Face Transformers)
Experience with vector databases (such as Pinecone, FAISS, Weaviate) and RAG pipeline implementation
Proven ability to evaluate AI systems through custom evals, benchmarking, or data curation
Experience deploying AI solutions through RESTful APIs and web services
Familiarity with agentic AI concepts (tool-use, planning, multi-step reasoning), with a practical sense for when simpler systems suffice
Strong grounding in software engineering principles (version control, modular design, testing) and commitment to measurement-driven iteration
Excellent communication skills and the ability to explain complex AI solutions to non-technical stakeholders.
Strong understanding of AI ethics, bias mitigation, and responsible AI practices
Nice to Haves
Experience in Node.js, React.js, or previous background in software development would be an added advantage.
Experience with model fine-tuning, knowledge graphs, or multi-modal AI systems.
Familiarity with AWS services for scalable GenAI deployment and MLOps practices
