About Finofo

Finofo makes global finance effortless. We help companies pay vendors, move money across borders, manage multi-entity cash, and stay compliant — all from one platform.

We’ve raised over $5M, including a $3.3M seed led by Watertower Ventures, with Motivate VC, and SaaS Ventures. The opportunity is real, and so is the urgency. Customers are scaling fast — and now the product has to scale faster.

Why We’re Hiring

We’re not here to build a nice little app. We’re here to build something category-defining — and that takes obsession, effort, and ownership.

We’re looking for a Back-End Engineer who can build fast, iterate faster, and work tightly with our Front-End Engineers and UI Designer. You’ll help us wire up real product features with real-world consequences, and when the design has to change mid-implementation, you’ll collaborate with your team to make adjustments on the fly, without drama..

This is not a maintenance role. This is foundational build work, and we need someone who’s ready to meet the moment.

What You’ll Do

• Build and evolve core back-end systems using Python and PostgreSQL
• Own APIs that power key product flows, and shape how they evolve
• Work side-by-side with front-end engineers and designers to iterate fast and ship UI-driven features
• Write and maintain tests, and monitoring for your services
• Participate in architecture discussions and raise the bar for system design
• Own production issues end-to-end: investigate, fix, and follow through
• Ideate, iterate, and debug live with the team; even if it’s 9PM on a Friday

Who You Are

• 8+ years of experience designing, building, and operating back-end systems in production at scale
• Expert in Python (or a similar OOP language), with strong proficiency in PostgreSQL
• Proven track record in API design and hands-on experience with cloud infrastructure (preferably AWS)
• 2+ years of hands-on experience with AI/ML — building classifiers, training models, and applying machine learning techniques in production
• Founder-speed mindset: you put in the effort it takes to win
• You understand that back-end decisions shape front-end experiences — and vice versa
• You prefer to work closely with people: designers, front-end devs, product
• You communicate clearly, give direct feedback, and take ownership
• You don’t measure success by tickets closed, but by what actually gets shipped and works
• Bonus: fintech experience or experience in another industry where some features just can’t start failing randomly, this is not a gym planning app.

Let's Be Honest

This isn’t a lifestyle job. We’re building a VC-backed company with global ambition. That means intensity. We’re not training for a casual 5K jog — we're trying to win gold at the Olympics of Tech.

That requires more than talent and smarts. It requires hours, effort, resilience, a winning attitude and pride in your work.

If you're looking for a cushy 9 to 5 job, this isn’t the place. But if you're looking for meaning, impact, and the chance to do your life’s best work, let’s talk.

How We Use AI

We’re obsessed with speed and leverage every edge we can. From Cursor to Codex, we use AI to write, review, and refactor faster. We’re always on the hunt for new tools that boost engineering velocity. The pace of innovation in AI is accelerating, and we don’t plan on being laggards. If you're AI-curious and love experimenting to move quicker, you'll fit right in.

• Equity with real upside. Participate meaningfully in the win.

• High-trust, high-responsibility culture where builders thrive
