You'll be the senior engineering anchor of our Lisbon AI hub. You'll ship production-grade agentic AI systems for enterprise clients (orchestration, RAG, evals, deployment, observability) AND own the data plumbing they depend on (dbt models on a warehouse layer over HubSpot and client data).
The AI Team today has more qualified AI requests in the pipeline than engineers capable of taking them from prototype to production. You change that.
You'll ship 3+ production agentic AI systems to enterprise clients within 12 months (deployed, signed off, in active use)
You'll build and maintain our reusable agent framework: tool-calling layer, prompt management, evals harness, observability, usable by future AI Engineers across all sites
You'll build and operate the internal data warehouse layer (dbt models, source freshness checks, tested transformations) for both client AI engagements and internal analytics
You'll establish our evals and data quality bar: every shipped agent gets documented evals, drift monitoring, and a rollback plan; every shipped pipeline gets tests and freshness SLAs
You'll maintain ≥ 85% billable utilisation across active engagements
You'll co-author 2+ public-facing technical assets (blog post, webinar, conference talk) on our AI or data engineering approach
You'll contribute to AI proposal and scoping conversations as the technical authority alongside Sales and Advisory
Must-haves
Direct experience building and shipping agent systems using tool-calling LLMs (Claude, GPT, Gemini) to production. You understand tool schemas, multi-step reasoning, error handling, retries, observability
Hands-on data engineering experience with dbt (or comparable), modeling CRM or B2B data into a clean dimensional layer, operating a warehouse (BigQuery, Snowflake, Postgres, DuckDB, or similar) under change control
Production RAG experience with vector stores (Pinecone, Weaviate, pgvector), hybrid search, re-ranking, and chunking strategies that actually work for enterprise documents
Evals and data-test discipline. You don't ship without them. Automated eval suites (golden datasets, LLM-as-judge, regression tests) and dbt-style data tests treated as production code, not notebooks
Production engineering hygiene: maintainable Python or TypeScript, tests, types, CI, deployment, cloud fluency (AWS, GCP, or Azure), Docker, basic IaC
Cost and latency awareness. You read token cost and warehouse cost like an SRE reads CPU. You know when to cache, when to fine-tune, when to switch models or pre-aggregate data
Native-level Portuguese plus clear business English.
Nice-to-haves
Experience integrating AI or agent systems with HubSpot, Salesforce, or comparable enterprise CRM platforms
Prior experience as the senior engineering anchor on a distributed team across multiple time zones
Public open-source contributions or shipped commercial AI products
Experience building or contributing to an internal agent framework or LLM tooling layer
You'll join the AI Team within our Development & Technology Practice as the Lisbon anchor. You'll report to the Director Development & Technology, with day-to-day collaboration with Senior Engineers across the Practice. You'll partner closely with the Tech Consulting team on solution architecture, the Development team on integration work, and the Consulting Practice (Advisory) on AI proposal scoping.

Thorit is one of Europe's leading HubSpot partners and a top business and technology consultancy. We combine strategic advisory with hands-on IT implementation, from CRM architecture to fully automated go-to-market infrastructure powered by AI and agentic systems.
Send your application via Ashby. A cover letter is optional, but a concrete example of the most complex agent system you've personally shipped to production (architecture, tooling, evals, rollout, what broke and how you fixed it) is required.
Build agent-driven and retrieval-augmented AI systems for legal work, improve LLM quality through fine-tuning and evaluation, and develop scalable search and document-processing pipelines.
Leads architecture and delivery of AI engineering projects, building reliable systems for agentic execution, model orchestration, and enterprise workflows while guiding engineers and shaping technical direction.
Build and operate AI agents that automate infrastructure workflows across SRE, DevOps, and database operations, designing reliable, safe systems that interact with production infrastructure.
Develop and deploy AI and machine learning solutions for autonomy and intelligent systems, taking work from early experimentation through production in safety-critical environments across defence and aerospace programmes.
Develop computer vision and deep learning algorithms for centimeter-level vehicle localization on HD maps, combining multi-camera vision, 3D geometry, and optimization for robust autonomous driving.
