Forward-Deployed AI Builder
Hexa
Paris, Île-de-France 75000, France
CDI
The role in one line
Hexa Scale's forward-deployed AI builder - the person who turns the firm's and the portfolio's AI ambitions into shipped agents, working workflows, and team-wide AI fluency.
Why this role exists
The Managing Partner and Operating Partner own investment selection, value-creation plans, and the strategic transformation conversations with portfolio CEOs. What we are missing is a dedicated builder and enabler who:
Think Forward-Deployed Engineer with an AI specialty and the maturity to operate independently in front of executives - but without yet owning IC-level strategic calls.
Key responsibilities
1. Be Hexa Scale's in-house AI builder (internal enablement)
Working under the direction of the MP and OP, build and ship:

Why this role exists
The Managing Partner and Operating Partner own investment selection, value-creation plans, and the strategic transformation conversations with portfolio CEOs. What we are missing is a dedicated builder and enabler who:
- Ships the internal AI tooling that makes Hexa Scale move faster than any other PE firm in Europe.
- Embeds with portfolio companies to actually build the first agents and AI workflows - not just advise on them.
- Is hands-on enough to teach the deal team, the operating team, and portfolio operators how to use AI in their daily work.
Think Forward-Deployed Engineer with an AI specialty and the maturity to operate independently in front of executives - but without yet owning IC-level strategic calls.
Key responsibilities
1. Be Hexa Scale's in-house AI builder (internal enablement)
- Build and maintain internal agents and scripts that compress repetitive work for the deal, operating, and finance teams.
- Own the rollout of our internal AI stack (LLM tools, agent frameworks, knowledge base, evals).
- Run regular "AI clinics" and short workshops to lift daily AI fluency across the team.
Working under the direction of the MP and OP, build and ship:
- Market intelligence agents tracking signals across European vertical SaaS sub-segments.
- Sourcing & pipeline agents that enrich and prioritize targets.
- DD support tools: data-room ingestion, customer-call analysis, KPI extraction, AI-readiness checks.
- Reporting automation for portfolio monitoring and LP communications.
- Provide the technical AI lens during DD: tech & product audit, AI-readiness scoring, data-asset evaluation, agentic opportunity sketches.
- Surface findings as structured inputs to the deal lead and the IC memo - strategic decisions stay with the MP / OP.
- Embed with portfolio companies in short sprints (typically 2-8 weeks) to build the first AI use cases: ship the first agent, integrate the orchestration layer, set up evals, get something into production.
- Train internal counterparts so the work scales after the sprint ends.
- Capture reusable components and playbooks for the next portfolio company.
- This means regular travel to portfolio companies across France and Europe - expect to be on-site for a significant part of your time.
- 4-6 years of experience as an applied AI/ML engineer, Forward-Deployed Engineer, founding engineer, or applied AI consultant.
- Has shipped multiple LLM-powered or agentic products in production - comfortable with LLM tooling, RAG, evals, and integrating into messy enterprise codebases and data.
- Builder mindset and high tempo: loves shipping, ships fast, iterates faster.
- Comfortable parachuting into an unfamiliar codebase, vertical, or company and getting traction in days, not months.
- Strong communicator; can teach AI to non-technical executives and operators.
- Business-literate - cares about ROI and adoption, not just elegance - but not aspiring to be a deal partner.
- English fluent; French is a strong plus.
- Genuinely excited about travel - this role isn't remote-first. You'll be on the ground with portfolio teams across France and Europe on a regular basis.
- Background in vertical SaaS, B2B SMB software, or developer tools.
- Experience designing agent orchestration, RAG over messy enterprise data, or AI evals/observability.
- Prior FDE or applied AI consulting role with regular C-level exposure.
- Comfort working across multiple European geographies and languages.
- Several production-grade internal agents owned by Hexa Scale across sourcing, DD, and reporting.
- Every Hexa Scale team member is measurably faster in their core workflows thanks to internal AI tooling and coaching.
- Every active DD has a structured AI-lens analysis delivered by this role.
- At least one portfolio company has launched a first AI agent in production with this role on the build, and a local team trained to extend it.
- A growing library of reusable AI components and playbooks is being shared across the portfolio.
- Package: €72K to €85K gross/year (base salary of €60K-€71K + 20% annual profit sharing)
- Opportunity to invest in Hexa portfolio startups at a (very) preferential rate
- Swile meal card
- 8 to 12 RTT days per year
- Mobility budget: €500/year for green transportation (bike, metro, electric scooter)
- Health insurance with 50% coverage for you and your family
- 1% Holiday bonus
