Job summary

Artefact is seeking a Senior AI & Agentic Engineer to design and build end-to-end AI features—from React front ends to Python/Node services, RAG pipelines, and data integrations.

You will own components end-to-end, work with leading AI platforms (Google/Anthropic/OpenAI), and engage with clients directly while mentoring junior engineers and raising engineering standards.

Qualifications

• 3–5 years of experience in software or data engineering with hands-on AI tools.
• Strong programming in Python and TypeScript/JavaScript; API development.
• Experience with front-end (React) and at least one backend framework.
• Hands-on with RAG, embeddings, vector search; experience with an agentic framework.
• Experience with major AI platforms and one cloud platform.
• Fluency in English (C1/C2).
• Bachelor's or Master's in CS/engineering.

Responsibilities

• Build AI products across the full stack from interface to infrastructure.
• Develop UI in TypeScript/React and backend services in Python/Node.
• Implement agentic behavior: orchestration, tool calls, memory, guardrails.
• Build RAG pipelines: ingestion, chunking, embeddings, vector search.
• Connect AI systems to enterprise data via APIs and MCP; work with clients.

Job description

About Artefact

Artefact is a next-generation data and AI consulting firm dedicated to accelerating the adoption of data and AI to create measurable business impact across the full enterprise value chain. We sit at the intersection of consulting, data science, AI technologies, data engineering, and digital transformation. We do not just advise — we build, implement, and deliver results our clients can measure. Our teams bring together consultants, data scientists, data engineers, AI engineers, analysts, and digital experts to solve complex business challenges with pragmatic, production-ready solutions. As Artefact continues to grow globally, we are building a team of entrepreneurial data and AI talent who can help clients move beyond experimentation and into scalable, governed, value-generating AI adoption.

The Role

Artefact is looking for a Senior AI & Agentic Engineer: a full-stack engineer who takes AI features from idea to production. You will design and build the interfaces, services, and agentic systems at the heart of our client work, such as conversational applications over enterprise data, multi-step agents that automate business workflows, and the retrieval and data pipelines that support them. You will own your components end to end: the React front end, the Python or Node service behind it, the RAG pipeline feeding it, and the evaluations proving it works. This role combines breadth and depth: the ability to take a feature from front end to cloud deployment, together with strong expertise in at least one major AI platform — Google (Gemini), Anthropic (Claude), or OpenAI. You will work with direct client exposure, and you will support the professional development of the junior engineers around you.

What You'll Do

You will build AI products across the entire stack, from interface to infrastructure.

• Develop user-facing interfaces in TypeScript/React and the backend services and APIs behind them in Python or Node.
• Implement agentic behavior: orchestration, tool and function calling, memory, and guardrails.
• Build retrieval-augmented generation (RAG) pipelines: ingestion, chunking, embeddings, vector and hybrid search.
• Connect AI systems to enterprise data and applications via APIs, semantic layers, and protocols such as MCP.

Make AI Systems Production-Grade

Our standard is production quality: systems that are reliable, monitored, and maintainable.

• Write evaluation suites and regression tests for LLM-powered features, and monitor cost, latency, and quality in production.
• Apply solid engineering practice: version control, code review, automated testing, CI/CD, and observability.
• Deploy on cloud infrastructure (GCP, Azure, or AWS) using containers, serverless, and infrastructure-as-code.
• Build and maintain the data pipelines that feed AI systems, across warehouses, lakehouses, and vector stores.

Work AI-Natively and Client-Facing

Our engineers work AI-natively and represent Artefact directly with clients.

• Use agentic coding tools (Claude Code, Gemini CLI, Codex, Cursor) daily, with good judgment about verification and review.
• Communicate progress, trade-offs, and blockers clearly to clients and project leads.
• Support pre-sales when needed: scope solutions, build demos, and estimate effort with our partnership and consulting teams.
• Mentor junior engineers and contribute to internal accelerators, reusable components, and engineering standards.

What We're Looking For

Required Experience

• 3–5 years of experience in software engineering or data engineering, with extensive hands-on use of AI tools and LLM-based development over the past year (professional projects, internal initiatives, or substantial personal builds).
• Strong programming skills in Python and TypeScript/JavaScript, and experience building and consuming APIs.
• Experience with front-end development (React or similar) and at least one backend framework.
• Hands-on experience with RAG, embeddings, and vector search, and with at least one agentic framework (LangGraph/LangChain, Google ADK, Claude Agent SDK, or OpenAI Agents SDK).
• Specialization in at least one major AI platform ecosystem — Google (Gemini, Vertex AI, Gemini Enterprise), Anthropic (Claude, Managed Agents, MCP), or OpenAI (Responses API, AgentKit) — and working experience with one cloud platform (GCP, Azure, or AWS).
• Fluency with agentic coding tools such as Claude Code, Gemini CLI, Codex, or Cursor.
• Experience building and maintaining data pipelines.
• Professional English proficiency (C1/C2 minimum) — mandatory. You will work daily with international clients and colleagues.
• Bachelor's or Master's degree in computer science, engineering, or a related field, or equivalent practical experience.

Certifications

A certification on at least one major AI platform or cloud is a strong differentiator at application. If you do not hold one yet, obtaining one within your first 2 months in the role is a requirement — Artefact sponsors the exam and gives you time to prepare.

• Examples: Claude Certified Developer – Foundations (Anthropic), Google Cloud Professional Machine Learning Engineer, Google Cloud Generative AI Leader, Microsoft Azure AI Engineer Associate, or equivalent AWS credentials.

Preferred Experience

• Experience with MCP servers, multi-agent patterns, or LLM evaluation tooling (LangSmith, Langfuse, promptfoo).
• Experience with Terraform or CI/CD pipelines.

Key Capabilities

A strong candidate will bring:

• Breadth across the full stack, with depth in at least one AI platform
• Owns features end to end, from interface to infrastructure
• Cares about evaluation and reliability, not just the happy path
• Communicates clearly with clients in demos, documents, and code review
• Client-facing mindset: understands client needs and translates business requirements into technical solutions
• Learns new tools and models fast, and shares what works

What We Offer

• Meal (VR)
• Free Office (work from home or anywhere you want!)
• Gympass
• Insurance: Life, Health, and Dental
• Bi-monthly Meetings (our "Get Together" where we meet to be together, with workshops, lectures, training, and a happy hour!)
• Woba (you can book coworking spaces anywhere you want!)
• Semi-annual evaluations (with opportunities for promotion)

Why you should join us

• Artefact is the place to be: come and build the future of marketing
• Progress: every day offers new challenges and new opportunities to learn
• Culture: join the best team you could ever imagine
• Entrepreneurship: you will be joining a team of driven entrepreneurs. We won’t give up until we make a huge dent in this industry!
