AI Architect

on a flagship engagement with a

European private investment group

— a holding company with a C-level executive team, an investment/portfolio function and an affiliated family office. The programme builds

one private, access-scoped context layer over the group's data

— calls, email, Slack and messengers, board protocols, decks, portfolio updates — and then

AI skills and agents that run on it

: first for the executive team, then for every employee. Two loops sit on the same layer: alignment (strategy, OKRs and goal drift made visible) and efficiency (a process miner that reads real workflows from the digital footprint, then optimizer agents that ship the automations). Four phases —

Capture → Connect → Distill → Build

— over roughly

eight to ten two-week sprints

, opening with a fixed-fee two-week

Sprint 0 readiness pass

(data-access audit, ontology spec, legal checklist across jurisdictions). A family-office workstream runs in parallel on the same squad. This is deliberately

not

a wrapper around an off-the-shelf platform. The client wants infrastructure they own, deployed privately, with role-based access for people and full visibility for the AI. The same architecture becomes a

NeuronsLab product line

, so you are designing something that has to survive being redeployed for the next client.
Stage: pre-contract / design-partner negotiation. Duration: multi-phase, ~4–5 months to production for the executive pilot, with rollout beyond it. Reporting: CTO (@Alex Honchar) and CEO are in the room at every key point — architecture, sprint planning, sprint reviews. You own the technical decisions between those points, working alongside an AI Analyst (1.0 FTE) and a Data Engineer (0.5 FTE), plus the client's Head of Security from day one.
This role is full-time.
What You'll Actually Do (example Tasks)

Run the Sprint 1 decision spike and write the decision record: one central private-cloud store vs.



a semantic layer over the existing systems of record vs. ready platforms (Gemini Enterprise, Glean-class, Cohere-class, open components) — scored on security, access control, speed, cost and reversibility.
Design the ontology / semantic layer for the group: entities, relationships and business definitions spanning people, meetings, decisions, commitments, goals, deals, portfolio companies and documents.
Architect the connector layer as an execution layer, not just an ingestion layer — MCP / tool-calling (Composio-class or built) so agents can act in HubSpot, mail, Slack and internal systems, not merely read a stream of data.
Design role-scoped retrieval: the principle is that AI sees everything and people keep role-based access. Make that enforceable at the retrieval layer, not just in the UI, and evidence it to the client's security function.
Architect the agent layer: per-executive skills (Chief of Staff / CIO / CFO / COO), the OKR & drift coach delivered in Slack, and the process miner → optimizer chain.
Choose and stand up the private deployment — VPC / on-prem / managed, model selection and routing, cost and latency envelopes.
Build the eval and observability harness: correctness, groundedness, access-boundary tests, regression suites before anything reaches an executive.
Establish standards and failure-mode design — human-in-the-loop boundaries for agents that take real actions, audit trails, rollback.
Stay hands-on: implement the critical pieces yourself, review the pod's work, and keep the build portable enough to redeploy as a NeuronsLab offering. xqbhyrx
Explain all of the above to a C-level audience in plain language, in review sessions and working groups.
Skills

Agentic system architecture end to end: retrieval, tools,



orchestration, memory, evals, guardrails
Ontology / knowledge-graph engineering and semantic layers over heterogeneous sources (RDF/OWL, Neo4j, dbt-style modelling — pragmatism over purity)
RAG / GraphRAG at production quality, including hybrid retrieval and permission-aware retrieval
MCP, tool-calling and connector platforms; designing agents that perform actions with side effects safely
Private / sovereign deployment: VPC, on-prem, self-hosted or open-weight models; AWS and/or GCP data + AI stack
Identity, access control and data governance applied to AI systems (RBAC/ABAC, scoping, audit)
Strong hands-on Python; comfortable writing the hard 20% of the code yourself
Evals & observability for LLM systems; treating quality as measurable, not anecdotal
Advanced written and spoken English; can hold an architecture conversation with a CIO and a CISO in the same meeting
Knowledge

The current enterprise context-layer landscape — Glean-class platforms, Cohere-class "AI OS" products, Microsoft Copilot / Agents, Gemini Enterprise, Palantir-style foundries — and where each genuinely differs
GDPR and data-residency constraints for multi-jurisdiction European groups; what makes a private deployment defensible
Financial services / private-equity context — investment policy, portfolio reporting, board process — a strong plus
OKR / goal-management mechanics, enough to architect for them
Experience

7+ years hands-on AI/ML engineering, of which 2+ years building LLM / agentic systems in production
3+ years as technical lead or architect on client-facing delivery
Demonstrated ontology / knowledge-graph or semantic-layer work over messy real-world enterprise data
Experience with regulated or security-sensitive clients (BFSI, government, healthcare) and private deployment
Experience in consulting or a services business — comfortable being the technical face to a C-level client
Comfortable as the most senior technical person on a 2.5-FTE pod, with founders as sparring partners rather than a safety net
