Job description

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

Dex is an AI recruiter agent that helps you run your job search. Tell Dex your stack, seniority, and what you want to build. We will manage your applications and surface other opportunities that are a fit.

The role

Statutory audit is still defined by manual sampling, months of opaque back-and-forth, and spreadsheet chaos. Backed by top European venture funds, this pre-seed startup is rebuilding audit from the ground up as an operating system for European businesses. Instead of manually inspecting a random sample of invoices, their deterministic data engine tests every single transaction—delivering upfront fixed pricing, 20-minute onboarding, and full sign-off from state-authorised auditors.

As Founding Engineer, you will own the agent layer from day one: the autonomous system that plans, executes, and validates audit work, alongside the machinery that allows it to improve from auditor feedback. This is a role for an engineer who wants to solve ambiguous, one-line business problems directly with subject-matter experts, not someone waiting for a groomed Jira backlog. If you want a predictable sprint schedule and predefined roadmaps, this will be the wrong seat; if you want to architect real-world agentic infrastructure in production, this is it.

The work

• Architect and own the autonomous agent layer that ingests financial data, plans audit procedures, executes tests, and verifies statutory evidence.
• Build the evals and continuous feedback loops that allow the system to learn and improve reliability from auditor interventions.
• Collaborate directly with state-authorised auditors to translate international auditing standards (ISA), materiality, and evidence thresholds into deterministic code.
• Own system reliability and execution workflows end to end across TypeScript, Fastify, React, Postgres, and Temporal.
• Set the foundational engineering standards, tooling choices, and technical culture as one of the first engineers on the ground.

What You Bring

• Demonstrated track record of shipping production systems you were personally accountable for end to end, not just contributing to shared repositories.
• Pragmatic, battle-tested opinions on LLM systems derived from measuring latency, reliability, and evals in production, rather than just prompting APIs.
• Ability to decompose complex, ambiguous real-world processes directly alongside domain experts and translate them into strict software specifications.
• Based in or relocating to Oslo, with a strong preference for working in-person alongside the team roughly four days a week.

Why apply through Dex

High-equity founding engineer roles in European AI are rarely advertised transparently, making it difficult to separate thin wrappers from serious infrastructure. Applying through Dex bypasses cold applications and gives you direct access to the founding team, armed with candid context on the architecture, runway, and equity structure before your first conversation.
