Backed by world-class investors and advised by industry titans, we’re building category-defining products with the freedom to ship ambitiously and own outcomes. Come help us make Light the global default for next-gen finance. This Senior Software Engineer role We're looking for builders who can take a customer problem from idea to production, wherever in the stack it lives. At Light, AI writes code and the bottleneck has shifted from writing to thinking, so we want engineers who work end-to-end and ship things that matter. We are primarily hiring at mid-level for this role. Junior candidates who are exceptional and genuinely AI-native are welcome. Senior candidates will be considered by exception; we have strong technical leadership and the bar is high. Your qualifications: 3-7 years of experience ideally, plus... * You build things. Not prototypes, not demos. Working software in production, doing something real for real users. This is the non-negotiable. * You're genuinely AI-native. You've changed the way you work because of AI tooling, not just added it to your workflow. You have an instinct for where it helps, where it misleads, and how to use it without losing ownership of the outcome. * You've built with LLMs. You have hands-on experience building products or features on top of large language models. Agents are a bonus, but working knowledge of how LLMs behave in production is a must. * You're comfortable across the stack. You don't need to be a specialist in everything, but you can't have a lane you refuse to leave. Our stack is Kotlin and React. If you're strong in one and curious about the rest, that works. If you need someone else to handle the other side of the feature, it doesn't. * You care about the product. You think about the person on the other end. You notice when something feels clunky, even if it technically works. You have opinions about what good software feels like and you act on them. * You ship early and often. Small batches. Learn. Go again. You're not precious about your work. You'd rather put something real in front of a customer than spend another week perfecting it in isolation. Bonus points: * Experience in fintech or systems where data integrity is non-negotiable * Familiarity with accounting concepts: debits, credits, reconciliation * Background in high-growth startups where everything was still being figured out Our Tech Stack: We build on AWS, with a Kotlin backend, a React frontend, and infrastructure managed in Terraform. It's a real production system that global finance teams depend on every day. You don't need to have used every piece of it. You do need to be comfortable in this kind of environment: real scale, real customers, real stakes. The good stuff In addition to being part of a great team and working in a really fun and innovative environment, we offer: 💸 A competitive salary + potential stock options 🏝 25 days of annual leave + public holidays in the country where you are based. 🥳 Regular socials and company off-sites 🚀 A huge opportunity for career growth as you'll help shape a market-defining product.

Bonus points: * Direct experience integrating with card networks, payment gateways, or banking partners. * Built or scaled payment services in a high-growth startup. * Familiarity with AWS infrastructure, Docker, or Kubernetes. Our Tech Stack: * Hosted on AWS * Postgres DB * Kotlin Monolith Tips to stand out * Show us who you are through your application and don’t limit yourself to a resume. * Share examples of payment projects or integrations you’ve built and delivered. * Bring metrics to back up your impact (e.g. transaction throughput, time-to-market). * Tell us why you want to help build Light’s payments foundation.
