About the role


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.


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 React application using NextJS, TypeScript, and TailwindCSS, hosted on Vercel.

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 never NextJS or 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: We are backed by top-tier VCs (Y Combinator and Seedcamp) which gives us a great network to collaborate with and learn from + you can get direct access to world-class engineering mentors. Choose where you would like to work: If you're remote and want an office 3 minutes walk from you, go get it. An equity package to make you feel like a real owner All the latest tech equipment you need. Health, vision and dental care included in your personal insurance. Monthly budget to spend on books and conferences to ensure you are always up-to-date with the latest developments in your field. Missing something? Just let us know what it is and we can talk about it.

Why you should join LiveFlow

We're building LiveFlow to help companies manage their finances with confidence and ease.

Every company has to control its budget and its cash, but too many startups drown before they ever get to see regular and reliable numbers. The lucky ones invest a ton of time and tedious effort to pull their disparate data together every month. For most, the solution is a mix of fragile spreadsheets and flakey scripts. We want to fix that.

Don't get us wrong; spreadsheets are an amazing tool – and scripts can be pretty great too! Spreadsheets are so useful in fact that it's estimated that as many as one billion people use them every month¹. However... Their flexibility and versatility come at the expense of simplicity and maintainability.

We can do better by allowing businesses to easily integrate their own financial data sources. We can do better by automatically updating reports and dashboards, as soon as new data becomes available. We can do better by intelligently detecting errors, anomalies, and even opportunities.

We believe that we can do even better than that.
