Senior Back End Engineer I

Thought Machine

Thought Machine's mission is bold – to properly and permanently rid the world's banks of legacy technology. To achieve this, we have developed the foundations of modern banking through core and payments technology which run natively in the cloud. What we are attempting is hard and means we need great people working together to build great technology. We have grown rapidly in the past few years – growing our team to more than 550 individuals across offices in London, New York, Singapore, Sydney and our newly established Engineering Hub in Lisbon. We have raised more than £500m in funding and our investors include Molten Ventures, Eurazeo, Intesa Sanpaolo, Temasek, Nyca Partners, JPMorgan Chase Strategic Investments, Standard Chartered Ventures, and more. We have created a culture that enables our team to produce the best work in the industry while ensuring we have fun along the way. We're regularly cited as having a fantastic workplace culture and have been recognised by Sifted magazine as having one of the highest Glassdoor ratings for a UK fintech company and the industry's most generous employee share package. Named one of the world's most innovative fintechs by Global Finance Magazine, we were also recognised by the Financial Times as one of Europe's fastest-growing companies for two consecutive years—and a UK Best Employer for 2026. Software Engineering is a key role within Thought Machine. As an engineering-focused company, we take pride in our engineering excellence, adopting best practices, and utilising modern technologies. Thought Machine software engineers work across the stack to solve complex engineering problems that have not been solved before. As a result, while development at Thought Machine is fast-paced, you will be expected to develop code to the highest standards that scales, is secure, performant, and provides a great user experience. Software Engineers will take complete ownership of a requirement, converting it into an engineering design, task breakdown, and implementation. You'll be responsible for building both backend services and frontend experiences. Our clients range from the world's largest financial institutions to smaller regional banks. Our systems must cater to each of these use cases, so we care deeply about providing the ability to configure and customise the user experience based on the client's or end user's persona.

Bounce

💙 ABOUT BOUNCE... Bounce is building cloud storage for the physical world, starting with the largest global luggage storage network in existence. Bounce's marketplace connects travelers with 30,000+ small business locations worldwide for hyper-local short-term baggage storage. With more locations globally than Burger King, and more locations in New York City than Starbucks, Bounce has served 3M+ users, stored 10M+ bags, and paid over $10M to small business partners. To achieve this, Bounce is a fast-paced and scrappy team. We believe that experimentation fuels innovation, so we move quickly, testing new ideas and adapting in real time. If you're ready to make an impact in a high-energy, close-knit, and collaborative environment, Bounce is the place where you can move fast, think big, and shape the future of travel. Join us as we make the world a lighter, more accessible place! Bounce has been named the Inc5000's fastest-growing travel company in the USA in 2024 and is proudly backed by leading Silicon Valley investors, including Andreessen Horowitz, General Catalyst, and Sapphire. (Learn more about Bounce's Series B HERE and our Japan expansion HERE). ABOUT THE ROLE… As VP of Engineering, you'll own product delivery and engineering hiring at Bounce as we scale from a 25-person engineering team that ships fast to a 50+ person org that ships even faster. You'll inherit a sharp, senior-loaded team across four engineering managers — and you'll be accountable for what we ship, how fast we ship it, and the people we develop while doing it. You'll partner directly with our CTO. The CTO keeps the wheel on architecture, AI, and technical platform; you'll take ownership of product delivery, the engineering org, hiring, and the partnership with Product and Design. Together you'll set the bar for engineering at Bounce and grow the team for the next chapter of the company. You'll be based in Lisbon, in-office, and report directly to the CTO. WHERE YOU COME IN… * Own product delivery end-to-end — be accountable for shipping the product roadmap on time and at quality. Run the planning, sprint, on-call, and incident-response cadences with autonomy. * Manage through managers — coach our four engineering managers into stronger leaders. Make the hire/level/exit calls. Build a bench so Bounce always has the next layer ready. * Own engineering hiring — personally close the senior hires. Hire ~10-15 strong engineers in year one. Own the engineering brand externally — talks, writing, and the candidate experience. * Be a deep partner to Product and Design — build real working partnerships with our Head of Product and Head of Design. Roadmap, prioritisation, and scope trade-offs are made together. Push back when scope is wrong; absorb it when it isn't. * Be a real exec — the engineering voice on the leadership team. Make trade-offs explicit, communicate up and across, and represent engineering externally. * Partner deeply with our CTO on architecture, AI, and technical platform — you'll work through these decisions together. Bring the product-delivery lens, translate technical bets into engineering execution, surface what product delivery needs from them to ship, and help shape platform direction so it accelerates the team. YOUR PROFILE… * You've led engineering organisations of at least 25 people, ideally through a 25→50 or 50→100 growth phase. This is not the first place you'll do this. * You've been a manager of managers for 3+ years — EMs reporting to you, not just senior ICs. * You have a strong technical foundation. You can review a system design, push back on an architectural decision, and earn trust from your Staff ICs. You haven't been promoted away from the technology. * You've personally recruited and closed senior engineers. You treat hiring as a primary part of the job, not something you delegate. * You're excited about being a deep partner to a hands-on technical CTO. You can build a real working relationship without ego, and you know how to make a CTO better at their job by taking the right things off their plate. * You move fast and treat speed as a feature. You don't bring a 50-page process playbook — you bring judgment. * Marketplace, consumer, and physical-world operations experience is a strong plus. So is having been part of an engineering culture known for shipping (Linear, Ramp, Stripe, Vercel, GitHub, DoorDash, etc.) * You're based in Lisbon or willing to relocate — this is an in-office role.
