Why work with us?
Fuelfinance is on a mission to revolutionize financial management for early-stage startups, empowering them to take control of their finances and thrive. We recently raised $1M in Seed Funding from top-tier investors like Markus Villig (Bolt), John S. Kim (SendBird), Stratmind, and Bad Ideas funds, following 3 years of profitable, bootstrapped success. Trusted by businesses with over $200M in P&L, including Reface, Petcube, and Hampton, we've built a universal tool that brings clarity and insight to finance management.
With 38% of startups failing due to cash flow issues, our goal is to prevent these failures and unlock trillions in GDP growth. At Fuelfinance, we're not just creating software — we're safeguarding the future of thousands of startups. Join us and be part of this impact!

Who are we searching for?
We're looking for a Senior Full-Stack Developer to help build the next generation of our product: AI-powered finance agents that automate financial workflows for startups and SMBs.
You'll join at the moment this transition is happening — the work is greenfield, fast-moving, and shipped to real paying customers. You'll own features end-to-end across the stack, from architecture decisions to production monitoring, and build with AI as your default workflow. This isn't a role for someone who waits for tickets; it's for an engineer who spots problems, proposes solutions, and ships.
You'll join a team of 4 engineers, 1 QA, and a Product Owner, reporting to the Head of Engineering.
- AI finance agents: forecasting, financial analytics, automated workflows
- MCP infrastructure and the agent orchestration layer
- Integrations with accounting platforms, banks, and payment systems (QuickBooks, Xero, Stripe)
- Dashboards, access controls, and reporting infrastructure
What are your responsibilities?
- Design, build, and own features end-to-end across the stack — from architecture decisions to production monitoring
- Build with AI as your default workflow: agentic coding tools with proper codebase context and end-to-end test verification
- Develop agentic AI workflows: LLM-powered features with proper context management, tool use, and automated end-to-end testing
- Make pragmatic technology choices and defend them — weighing cost, speed, and long-term maintainability
- Identify problems and propose solutions before they're assigned to you
- Keep security and data integrity at the core of everything
- Estimate, communicate risks early, and ship fast without cutting corners that matter
What are the preferred requirements for the role?
- 6+ years of software engineering experience with real depth
- Proficiency with AI-assisted development (a must) — not just chat-based usage: you know how to build agentic coding workflows, feed the right codebase context to models, and verify AI output with end-to-end testing
- Proficiency in both frontend and backend development
- TypeScript, Node.js (Nest.js), React
- SQL, MongoDB
- AWS knowledge
- B2/C1 English level
- Experience enhancing system and infrastructure security
- Proactive approach
- Comfortable with startup mode: shifting priorities, fast pace, high ownership
Will be a plus:
- Experience with LLM APIs in production (Anthropic, OpenAI), RAG
- Fintech background or experience on security-focused projects
- Knowledge of one of the following: C#, Java, Go, Python
- Early-stage startup experience
- Experience with infrastructure setup
This role won't fit if:
- You wait for clarity instead of creating it
- AI tooling is something you've read about rather than used daily
- You prefer a stable roadmap over shifting priorities and high ownership
Recruitment Process:
- Soft skills interview with the recruiter
- System Design & Experience Review with the Head of Engineering
- Culture fit interview with the VP of Operations
- Final Interview with the CEO
Why work with us?
- Build the future of finance work — design AI-native finance products, not just maintain them
- Rapid skills improvement
- Growth opportunities according to our seniority grading (it comes with a compensation increase)
- Flexible schedule and time-off policy
- 18 days of paid vacation per year, paid sick leaves

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
- Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
- Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
