Founding AI Engineer (gn) @ Pre-Seed AI-Native Enterprise Platform, Helsinki

This is an Atlantic Labs portfolio venture. Find out more about us and other opportunities in our portfolio here.

About the Venture

We’re a stealth venture building an AI-native platform for enterprise business modelling and scenario planning. At its core is a graph-based modelling engine combined with an intuitive grid UI and an AI co-pilot that accelerates model creation and improves decision quality.

Our goal is to replace Excel as the default for complex business models, while offering a more flexible and easier alternative to current heavyweight enterprise tools. It’s a new kind of tool for business controllers and FP&A leaders.

We’re a founding team of three with deep expertise in enterprise software, data modelling, and product execution. Backed by pre-seed financing, we’re working closely with design partners in the upper mid-market and enterprise space, and preparing to launch soon.

We’re establishing our HQ in Helsinki and would be excited to hear from you who are already based here or open to relocating. That said, we are open to hybrid arrangements within a reasonable aligned timezone.

About the Role

Weʼre looking for a hands-on AI/LLM engineer to own the design and implementation of the platformʼs AI capabilities end to end. Youʼll be responsible for how models reason over our grid + graph, for safety and reliability in enterprise environments, and for building agentic workflows that deliver practical value in complex modelling and variance analysis.

This is a zero-to-one role where youʼll pair research-grade curiosity with product pragmatism. You will collaborate closely with the founding team, shipping iteratively while laying the foundations for correctness, observability, and scale.

What You’ll Do

• Design and implement agentic workflows for model building, scenario generation, reconciliation and variance analysis
• Build reliable, auditable LLM pipelines: retrieval, tool-use, function calling, routing, and self-correction loops
• Integrate LLMs with our graph-based modelling engine and domain-specific DSLs and tools
• Establish evaluation frameworks: unit-style evals, golden sets, regression tests, and human-in-the-loop review
• Productionize prompt and policy governance for enterprise: safety, privacy, red-teaming, guardrails
• Own LLMOps: tracing, observability, cost and latency optimization, caching, batch inference
• Ship high-impact product features in tight loops with design partners and founders
• Contribute to core architecture decisions balancing speed with reliability and compliance

Requirements

About You

• Youʼve implemented LLM-powered features in production enterprise applications
• Hands-on experience building agents or complex tools - using systems beyond basic chat
• Strong software engineering fundamentals and product sense; you ship, measure, iterate
• Comfortable moving across the stack when needed and collaborating cross-functionally
• Pragmatic about model selection and trade-offs; you value reliability over hype

Nice to have

• Experience with graph-based data models, planning algorithms, or numerical modelling
• Retrieval design at scale, vector indexing strategies, hybrid search, and metadata filtering
• Practical grounding in evals and offline experimentation methods
• Prior work in FP&A, analytics, supply chain, or other multi-SKU enterprise domains

What success looks like in 3–6 months

• Agentic workflows reliably generate and explain scenarios over our graph + grid foundation
• Evals and traces catch regressions early; we can ship AI changes with confidence
• Enterprise-grade safeguards are in place: policy checks and auditability
• Measurable improvements to model creation time and decision quality for design partners

Why Join?

This is a true founding opportunity. Youʼll shape the AI architecture, agent patterns, and evaluation culture from day one, working on problems that are technically hard and meaningful for customers. If you want to define how enterprises reason about decisions with AI — and build a system that replaces spreadsheets for the real world — weʼd love to talk.

Location

Helsinki strongly preferred. Remote or hybrid possible within close timezones.
