(Learn more about Bounce's Series B HERE and also learn about our Japan Expansion HERE) WHAT IS THIS ROLE... Bounce is seeking a Product Engineer for New Verticals to join our Lisbon office. This role will play a pivotal part in crafting new products that expand what Bounce can do for travelers — beyond luggage storage — and bring us closer to our vision: a world where people can live life light, without thinking about their stuff. As a Product Engineer, you will take ownership of real customer problems and turn them into simple, delightful experiences across both backend and frontend. You’ll work on early-stage product surfaces, experimentation, and new flows that make traveling (and moving through cities) feel effortless. We’re looking for a generalist who thrives in ambiguity, loves shipping, and enjoys owning a feature from concept to production — collaborating closely with Product, Design, and teams across the company. HOW PRODUCT GETS BUILT AT BOUNCE At Bounce, we focus on serving our customers and partners rather than solely on technological innovation. We work in fast-paced 1-week cycles. Projects are usually scoped down to fit into one or two cycles. Projects are led by individuals, but are a shared effort across the entire team. There will always be aspects of any project that will require collaboration, feedback, and guidance—we expect you to ask for help. An ideal candidate is excited by all aspects of this software-building process, not just writing code. We’re a small team that thrives off of individuals who can take features from an idea to live on production. This is not a role where issues will be assigned to you and you churn through them. WHERE YOU COME IN... * Build and iterate on new product experiences across mobile and web, from idea → prototype → production. * Own customer-facing flows end-to-end: onboarding, booking, post-booking, and “make it feel magical” moments. * Collaborate with global teams to explore and validate new ventures, turning learnings into product direction quickly. * Write high-quality, maintainable code — and improve existing architecture as new verticals push the platform forward. * Contribute across the stack using Elixir, React Native/Expo, React, NextJS, and Typescript (and introduce new tools when beneficial). * Help shape how we build: fast cycles, high ownership, pragmatic experimentation, and strong craft. YOUR PROFILE... * Experience shipping production software. * Generalist that strives for velocity and loves owning a feature start-to-finish across the stack. * Strong coding skills in one or more of: Typescript/Javascript, Elixir, Ruby. * Experience with frontend frameworks (React / React Native) and a strong sense for UX polish. * Proven ability to build maintainable, testable codebases (API design, unit/integration testing). * Product-minded: you care about the end-user experience and the small details that make it feel effortless. * Comfortable working in ambiguity and iterating quickly based on feedback and results.

Lunar

About Us: Lunar is a stealth technology company building a new type of software platform for health systems. We are on a mission to revolutionize healthcare with cutting-edge, AI-powered software designed to help every hospital deliver world-class care for their patients. Our platform is already the core backbone of health systems today, transforming clinical and operational workflows at scale with the world’s first AI-native hospital information system. This next-generation platform is a fundamental rebuild of the information infrastructure that runs health systems. All of it – from doctors, nurses, pharmacists, lab technicians, coders, billers, supply chain, and even patients – Lunar’s software powers everything, soup-to-nuts. We believe that this mission is the moon landing of healthcare – something so consequential and ambitious that most people believe it to be impossible. Backed by Silicon Valley’s preeminent venture capital firms, we believe in the power of a high performance team of seasoned professionals operating at the peak of their abilities. We value people who are driven, curious, have sound judgement, and care about doing the best work of their careers. We run hospitals on Elixir. We’ve embraced Elixir for its fault tolerance, concurrency, and scalability - essential for handling real-time patient data in mission-critical settings like Emergency Departments, ICUs, and Operating Rooms. We are looking for a Senior Product Engineer who’s excited to tackle some of the hardest technical problems in healthcare - and do it with a fast-moving, and deeply mission-driven team. If you care about writing clean, robust code and want to rebuild from scratch the software infrastructure of modern hospitals, we’d love to talk. Here are some deep technical problems you may tackle in your first 6 months: * Modern cloud architecture, built from scratch: We have no legacy systems to untangle. We’re designing a modern cloud-native platform with Elixir at its core. * Develop a radically better access control system for clinical data: Create a modern access control system with fine-grained permissions that respects clinical data structure and patient data ownership, while enabling population-level insights for better public health. * Keep hospitals online 24/7 - no matter what: Design and ship infrastructure that can handle rolling deployments, failover, and real-time data sync in environments where downtime isn’t an inconvenience - it’s a risk to patient care. * Bridge the gap between software and hardware: Architect a next-generation integration engine to connect ventilators, bedside monitors, imaging equipment, lab equipment, and more - reliably and in real time. * Push hospital workflows into the modern age: Rethink and rewire how data moves between nurses, doctors, and administrators - and turn confusing, click-heavy workflows into fast, intuitive experiences. Your Experience:  * Minimum of 10 years of professional software engineering experience. * Proficiency with object oriented and functional programming, with the ability and willingness to use and adopt new technologies. We use tools such as Phoenix, Elixir, Python, Erlang, Javascript, and more. * Strong ability to work in a fast-paced, collaborative, and innovative team environment. * Exceptional problem-solving skills, with a track record of tackling challenging engineering problems.  * Intellectually curious with a growth mindset - able to tackle entirely novel challenges that lack prior precedent through applying strong fundamentals and first principles thinking. * Familiarity with open-source technology and a desire to explore and experiment with new solutions. * Experience building 0-1 with a strong product sense. * Excellent communication skills and the ability to articulate technical decisions, trade-offs, and best practices. * A passion for making a meaningful impact in the healthcare industry through software innovation is a plus. Hospitals are some of the most complex, under-served environments in all of tech. We’re bringing the best of modern software practices to an industry that’s been left behind - and building tools that clinicians love, not tolerate. If you’re an engineer who wants to work on meaningful problems with real-world impact, this is your chance. At Lunar, we know our greatest strength is the diverse blend of backgrounds, experiences, and ideas that our team members contribute. We’re passionate about healthcare, but we are also passionate about creating an inclusive workplace where every unique talent and perspective is not just respected, but celebrated. We thrive on embracing differences and are fully committed to fostering a fair, supportive, and dynamic environment where everyone has the opportunity to shine. All applicants will be considered for employment regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, veteran or disability status.
