Internal Tooling Engineer

About Finary

We're building a one-stop shop for investing that gives power back to individual investors. Finary lets users track their assets, manage budgets, invest money, and learn about finance, all in one place.

Launched in 2021, we've grown to 850,000+ users. In September 2025, we closed a EUR 25M Series B led by PayPal Ventures, with backing from Y Combinator, Hedosophia, Speedinvest, and founders from Qonto, Photoroom, Bitpanda, UBS, and Wise.

We care deeply about user experience, performance, and shipping products that genuinely improve people's financial lives.

TL;DR

You'll build the tools and AI-powered automation that make Finary's 28-person engineering team and every team across the company operate faster. Senior IC on the Platform team, working directly with internal stakeholders to identify friction and eliminate it. High ownership, direct access to users, and a real edge in AI engineering.

What you'll do

• Own the design, development, and maintenance of internal tools used daily across engineering, ops, product, and finance

• Build agentic AI workflows that automate repetitive internal processes and unlock new capabilities for our teams

• Work directly with stakeholders across all teams to identify friction and turn it into functional solutions

• Evaluate and integrate the latest AI engineering tools; you'll be our edge here

• Contribute to a polyglot codebase and collaborate with the broader engineering team on shared infrastructure

What we're looking for

• Software engineer with experience in high-paced environments

• You've shipped automated workflows and AI-powered tools in production (n8n, Dust, or equivalent), not just used them

• You've built for internal users before and understand that reliability matters more than polish

• You can navigate a polyglot codebase (Rust, Ruby, PostgreSQL) without slowing down

• You're based in Europe and can join us in Paris for onsite weeks every 6 weeks

Nice to have:

• Experience with developer experience or platform engineering

• Familiarity with fintech or a regulated industry

• Passion for personal finance and investing

Tech stack

• Primary: TypeScript

• Codebase: Rust, Ruby, PostgreSQL

• AI tooling: LLMs, n8n, Dust, Claude, Cursor, and whatever comes next

What we offer

Compensation

• Level 1 (learning the craft): n/a

• Level 2 (level 1 + autonomy): EUR 52-62k

• Level 3 (level 2 + ownership): EUR 65-75k

• Level 4 (level 3 + technical leadership): EUR 78-88k

• Level 5 (level 4 + shapes company direction): n/a

All levels include stock options. This role is open from Level 2 to Level 4 depending on experience.

Team

You'll report to the VP of Engineering and work as part of the Platform team. You'll have direct access to your internal customers from day one and the autonomy to shape how internal tooling works at Finary.

Benefits

• Hybrid setup: teammates across France and Europe, with in-person weeks in Paris 6 times per year (travel and accommodation covered)

• High-performing environment with A-players who challenge you and help you grow

• Impact that compounds: better tools today make every team more effective tomorrow

How we work

We ship fast and iterate constantly. We break complex problems into small pieces, get feedback from the people using our tools, and polish as we go. Internal tooling is not a backlog item at Finary; it's a strategic lever.

Even if you don't check every box, we encourage you to apply. We value diverse perspectives and are more interested in your potential than a perfect match to our checklist.
