About LiveFlow

We are building the next-generation accounting and finance platform to enable lean finance teams to run massive enterprises.

We have raised over $21M from top-tier investors including: YC, YC Continuity, Valar Seedcamp, WndrCo, Moonfire, Bradley Horowitz (VP Product, Google) and more.

We are helping thousands of companies to streamline their financial workflows and we have hundreds of 5/5 ratings on G2.

Our founding team previously worked at Europe's fastest growing fintech, Revolut.

🚀 WHY JOIN US?

You'll help shape your own role here as a function of your talent, your passion, and your ambition.

We want you to work smart, bring your own perspective, and ask deep questions about what we do and how we do it. You'll play a vital role in how we foster an inspiring culture, and in how we scale the organization in the coming years.

You love solving problems, right? That's why you're here. Well, we've got excited customers, eagerly awaiting your ideas and implementations. We've got tons of interesting challenges ahead – both technical and non-technical – and we definitely don't have all the answers yet, but we're striving to ask better questions every day.

Do you relish in the delight of customers, and in the opportunity to develop an amazing product you'll be proud of, and one they'll be happy to pay for? Do you have a keen eye for detail and design, but enjoy trading off perfection in pursuit of progress? Do you thrive in an environment of quick and collaborative iteration? If you're answering yes to those questions, we'd love to hear from you.

SOME OF THE TECH CHALLENGES YOU'LL HELP US MASTER INCLUDE:
  •  Building a real-time, collaborative financial workspace for teams

  •  Designing and developing a scalable and maintainable API

  •  Integrating with lots of different financial data providers

  •  Crafting beautifully simple abstractions to enable adaptable, frictionless UX

  •  Handling our own and customers' data securely and compliantly


OUR STACK:

On the backend, we've got an Elixir/Phoenix application, deployed on AWS via Terraform. On the frontend, we have a NextJS application using TypeScript.

We don't expect you to be an expert in every one of those areas.  

If you've enjoyed working in any functional language, we think you'll love Elixir (but if you've never even dabbled, we think you'll love it too). If you've felt productive working with a framework like Rails or Django, you'll get the hang of Phoenix in no time.

If you've worked with React, but not TypeScript, we can work with that. If you know your JS, but have never written React, that's fine too. You get the picture – it's not about your familiarity with specific technologies. If you're an expert in one or another domain, but open to learning as you go, we'll start from there.

Over time, we'll expect you to wear many hats. You'll be an architect balancing performance and pragmatism. You'll be a developer considering and implementing different designs. You'll be a product manager cutting and simplifying features. You'll be a leader and a mentor.

You're the kind of developer who knows not only what the best practices are, but understands why they are, and so knows when to ignore them. You're confident in making your case but open to alternative ideas, and willing to disagree and commit either way.

PERKS AND BENEFITS:
  • Competitive base salary and equity

  • Health insurance

  • Pension plan

  • All the latest tech you need; MacBooks, monitors, etc.

  • Monthly budget to spend on books and conferences to keep learning

  • Unlimited vacation policy
