AI Engineers Who Ship

GenAI engineers, data scientists and architects screened for a production track record — RAG, agents, MCP — including engineers who have shipped LLM systems for banks, where AI has to survive compliance. First CVs in 48 hours.

The AI ladder

We Place From Step Four Up

Everyone "works with AI" now. The ladder keeps the meaning in that phrase — we only present profiles from AI Developer upward: people who build systems, not people who use them.

Screening

Vetted Experts

CVs hide the gap between "did a GenAI demo" and "runs GenAI in production." We screen for continuity and depth — nothing else counts.

What we screen for
  • Python depth first — minimum 4 years in IT, ideally engineering-heavy, before the AI layer on top
  • At least a year hands-on with the working stack — agent orchestration (LangChain, LangGraph, CrewAI), RAG systems built and shipped, Model Context Protocol
  • Data engineering fluency — Pandas, NumPy, SciPy, Spark; models are only as good as the pipelines under them
  • Continuity of AI experience — a traceable path up the ladder, not a sudden 2024 rebrand
What gets a CV rejected
  • Prompt-only portfolios — impressive demos, no system behind them
  • Tool tourism — every framework name-checked, no production story for any of them
  • No engineering base under the AI layer — the projects fall over at the first integration
  • Experience that can't be walked through — if a candidate can't explain their own architecture decisions, the interview ends early
Regulated AI

AI That Survives Compliance

Banks want assistants and agents. Shipping them inside a bank is a different discipline — these four constraints are our screening bar:

Governed data access

Agents that aggregate across core systems without crossing a single permission boundary.

Privacy-safe aggregation

Answers built only from data the user is allowed to see — enforced in architecture, not in the prompt.

Hard action limits

An assistant that answers questions must refuse to move money. Guardrails are systems design.

Audit-ready by default

In banking a wrong answer is a regulatory event — logging, evaluation and traceability ship with v1.

The Profiles Behind the Claim

Real profile · anonymized Ladder step 6 · Solution Architect

Data/AI Architect — 15+ years

Owns system design under real constraints — architecture and delivery of LLM systems in regulated environments, from data governance to the boundaries of what agents may touch. Delivery track record with major UK and Nordic banks and PwC · podium finish in a global ML competition · M.Sc. Computer Science · with NDS since 2023. The profile banks ask for by name — and the blind CV that lands in your inbox in 48 hours.

AI Developer · AI Engineer, Python + GenAI

Owns production LLM features end to end — integration, retrieval, testing, monitoring, cost control. Engineering foundation first: 4+ years of software before the AI layer, minimum a year hands-on with the working stack.

Agent Developer

Owns multi-step agent systems — orchestration, tool use, hard boundaries, evaluation loops. The difference from step 4: the system acts, so guardrails and failure handling are the job, not an afterthought.

Data Scientist · Python + GenAI

Owns the data-to-model pipeline — embeddings, retrieval quality, fine-tuning, and the honest measurement of whether the system actually works before anyone claims it does.

PwC

A long-running delivery relationship, currently calling for AI and AML profiles. When a firm that audits everyone buys AI engineers, screening rigor is the product.

FAQ
How do you tell a real AI engineer from a prompt engineer?

Continuity and depth. We look for an engineering foundation that predates the AI wave — minimum four years in IT, ideally Python-heavy — plus at least a year of hands-on work with agent frameworks, RAG systems and MCP that the candidate can walk through decision by decision. Demos are ignored; architecture conversations are not.

Which stacks do your candidates work in?

Python-centric: LangChain, LangGraph and CrewAI for agents; RAG with hybrid search; Model Context Protocol; Pandas, NumPy, SciPy and Spark on the data side; Azure, GCP and AWS AI services in production. Other stacks on request — the screening method is the constant.

How fast can you deliver?

First matching CVs within 48 hours — the same contractual SLA as all our staffing. AI roles at Expert and Solution Architect level can take longer to close; we tell you the realistic timeline at the brief, not after three weeks.

Do your AI engineers have banking experience?

Yes — including engineers who have built LLM and RAG systems for banks and financial institutions, where data governance and guardrails are part of the definition of done. That experience transfers well to any regulated environment.

Staff augmentation or permanent hires?

Both. Most AI engagements start as staff augmentation for speed, with try-&-hire conversion when the fit is proven. Permanent recruitment runs through our IT Recruitment service with the same screening ladder.
