Lead Product Engineer TitanX Linköping

Retire the ERP. Light exists to replace factory-era ERPs with software that feels alive. Our Smart Financial Platform gives modern, global companies superpowers—automated accounting, real-time reporting, and financial flows that move at the speed of the business. We build with our customers, ship fast, and obsess over craft. In a short time, Light has gone from idea to the operating core for leading companies like Lovable, Legora, and Keyshot. People don’t just use Light—they enjoy it. We’re an early team defining a new software category. Think engineers who love debits and credits, designers who care about reconciliation states, and operators who treat finance as a product. If you’re excited to modernize how the world runs money—one workflow at a time—you’re in the right place. 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. How you would fit into the team This role sits at the heart of Light’s onboarding and engineering team. You’ll work closely with our clients, partners, banks and fellow engineers to build the money backbone of the Smart Financial Platform. Payments are a core pillar of Light’s mission — powering everything from cross-border transactions to automated accounting — and your work will directly shape how global businesses move money through our system. You’ll set up and maintain host-to-host integrations (mainly over SFTP and SWIFT-via-SFTP), exchange SSH and PGP keys, run payment and statement tests, and keep our payment pipelines healthy. It’s not pure software engineering, but you’ll read and write code when needed, debugging payment formats, checking database records, or improving an integration. If you like combining structured ops work with technical problem-solving, this role is for you. You’ll work in the Integration Delivery team, partnering with bank tech teams, customer success, and our engineers.

Your qualifications: * 2–3 years of experience building backend systems in payments, fintech, or financial services — ideally with H2H, SFTP, or ISO 20022 integrations. * Strong backend development skills in Kotlin, Java, Go, or Python, and solid understanding of databases (Postgres or similar). * Hands-on experience with payment file formats (PAIN and CAMT) and familiarity with SEPA, ACH, Wires, Faster Payments, CHAPS, and Bacs. * Clear communicator who can collaborate effectively with banks, customers, and teammates across time zones. * Structured, detail-oriented problem solver who takes ownership and continuously looks for process improvements. * Practical experience using AI or emerging technology tools to improve productivity, insight, or decision-making, with the ability to apply first-principles thinking to new problems. 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.
