Job description

First Circle is one of the fastest growing fintechs in South‑East Asia, providing financial services to under‑served SMEs. We have already transformed access to credit for thousands of small businesses in the Philippines, and we are now building a full‑stack Neobank from scratch that will include multi‑currency bank accounts, payments, FX, corporate credit cards, payroll.

We have just raised Series B, led by the IFC (the World Bank's investment arm), and we are hiring mid to senior level backend developers to supercharge our growth.

What's different about engineering at First Circle?

• Building in developing markets like the Philippines presents unique challenges, given the state of digital infrastructure. We are building virtually everything in house, which is not easy, but it is a lot of fun. We have a track record of solving seemingly impossible problems that defeated many other start‑ups, and the opportunity ahead remains enormous.
• We already have a core product that customers love – this is a unique opportunity to do zero‑to‑one building in a company that has already got a track record of delivering great things.
• Our team loves working together. No politics, just building. It matters.
• Our engineers are exceptional – they don’t just write code, they take away pain and spark joy for our colleagues and customers. They are the fintech revolution. Join today, become part of this unique team, and build something you can be proud of.

• At least 4‑5 years experience of software development.
• Great if you have worked on products that are data‑heavy, B2B, or fintech.
• You don't need to have mastered all the languages in our current tech stack (Ruby on Rails, Kotlin, React, HTMX), however you do need to be adaptable and keen to learn.
• The ability and desire to consistently produce excellent work, individually and as part of a team. Our mission is what attracts people, but working on highly stimulating problems is what keeps us hooked.
• Mindset of personal growth, and a best‑in‑class work ethic.
• We don't have a fixed budget for the role. When we find the right person, we will pay them competitively vs their market rate.
• Flexibility around working hours and location. The role can be worked remotely, with the option to work from one of our offices. We have offices in London, Hong Kong & Belgrade where other senior engineers are based.
• Macbooks, private health insurance, training budgets and more!
• Opportunity to travel to South East Asia.
