Location: Anywhere Workplace: Remote FINANCIAL SERVICES ARE BEING REBUILT FROM THE RAILS UP Stablecoins, programmable blockchains, and AI are changing how financial services get built. For a decade, fintech took legacy banking, wrapped it in better software, and won on experience. The rails underneath never moved. Now they do. Altitude is a new kind of financial services company. Banking becomes a module, programmable like the rest of the stack. On top of it we are building the global business account: hold USD and EUR, earn APY on idle treasury, send money anywhere via local digital payment systems, across 150+ countries, no US entity required. Built on Squads Protocol, the treasury infrastructure securing $10B+ in assets. Backed by Haun Ventures, Multicoin Capital, Electric Capital, and Coinbase Ventures. THE ROLE Product engineer is the job for people who want the whole arc: the problem, the design, the code, and the thing customers actually touch. You will work directly with founders and designers, take features from a rough idea to shipped, and own them after they ship. There is no layer of project managers translating between you and the product. The distance between "this should exist" and "this is live" is meant to be short, and you are the person who keeps it short. This is money infrastructure, so the bar is high. The interfaces should feel obvious. The code underneath should be careful. Both matter, and we do not trade one for the other. WHAT YOU WILL DO - Build customer-facing features across the stack, from the account experience down to the money movement underneath it - Work shoulder to shoulder with design on flows where clarity and trust are the product, not decoration - Ship payments, FX, yield, and treasury features on rails that settle 24/7 - Integrate with onchain infrastructure and a wide network of PSPs - Own performance, correctness, and the edge cases that matter more when real money is moving - Help shape what gets built, not just how it gets built, and push back when something does not feel right WHAT WE LOOK FOR - You have shipped customer-facing products end to end, and you can point to ones you are proud of - Strong fundamentals in TypeScript and React, and comfort working across the full stack - Product taste: you care about UX, speed, and polish, and you notice when something is off - High ownership. You do your best work with autonomy and a clear problem, not a ticket queue - Care for craft that shows up in the details, especially the ones nobody asked about - You move fast without getting sloppy BONUS, NOT REQUIRED - Background in fintech, payments, or anything where correctness and money intersect - Familiarity with Solana, smart accounts, or stablecoins - Experience with the Tanstack ecosystem, or building and maintaining a design system OUR STACK - Frontend: Typescript, SPA, Tanstack (Start, DB, Form), ElectricSQL, Zod, PandaCSS - Backend: Rust, Axum, Temporal, Postgres, Redis - Infra: AWS - You do not need every item on that list. You should be the kind of engineer who is glad to work this close to product, performance, and real money at real scale. HOW WE WORK Small team, high trust, fast execution. A few things we actually mean: - Craftsmanship excellence. Every contribution, whatever its size, meets a high bar - Bias for action. We would rather ship, learn, and correct than wait for certainty - Radical transparency. Respectful candor over comfortable silence - Kindness matters. It compounds, internally and with every customer WHAT WE OFFER - Competitive compensation with meaningful equity and real upside - Unlimited, flexible PTO and a flexible schedule - Company laptop and an allowance for whatever else you need to do your best work - Two company-paid off-sites per year

Location: London, England, United Kingdom About Wheely Wheely is redefining premium transportation across major cities in Europe, the US, and the Middle East. We blend cutting-edge technology with the craft of five-star chauffeuring to deliver an experience trusted by more than 100,000 active riders and 1,200 corporate accounts. We’re a profitable, fast-growing scale-up with $43M raised and over $100M in annual revenue. Having recently launched in New York City, we’re expanding rapidly across the US and EMEA. If you take pride in your craft and want to help shape the next chapter of our growth, we'd love to hear from you. About The Role We're rebuilding Wheely to be the fastest and most reliable ride-hailing app on the planet — one where both the passenger app and the driver app stay responsive on a flaky signal in the back of an apartment building, keep working behind censorship firewalls, and don't drop the real-time guarantees a moving car depends on. We're also adding something nobody in this category has built seriously: privacy as a product, not a compliance footnote. This role owns the core that makes all of that possible: the platform, the infrastructure, the privacy primitives the rest of engineering builds on top of, and the internal agent harness that lets teams across the company automate work that used to need humans. You'll inherit a mostly-Go codebase and a small group of strong engineers. You'll also inherit a genuinely open question on most of what matters. Is microservices the right end state, or did we default into it? How should a backend look in 2026 when AI has absorbed a large share of routine engineering work, when QA isn't a separate function, and when a small senior team paired with a few unusually strong grads can outship a 2019-style org several times its size? Our main engineering hub is in Cyprus. We're now building up London as a second hub, and this role is part of that — you'd be one of the first senior engineering leaders on the ground here, helping shape what London looks like as a location, who we hire into it, and what work belongs where. Responsibilities Own the technical direction of the platform end to end — including the architectural questions that haven't been answered yet, like whether to keep moving toward microservices or reconsider. Make real-time work, end to end. Driver app especially (location, dispatch, ride state) all of it under adversarial network conditions. Lead the privacy story on the engineering side — what's actually different about how data flows through our systems vs. every other ride-hailing company. Own and grow the agent harness so other teams can wire AI into workflows that used to need people. Today it's Rust. Tomorrow's shape is yours. Help build London as an engineering hub. That means hiring into it, deciding (with the rest of the leadership team) what work makes sense in London vs Cyprus, and setting the culture for a new office while staying tightly coupled to the main hub. Requirements You have designed backend systems from scratch (not only maintained, scaled, or rewritten what someone else built). We'll spend real time in the interview on the trade-offs you made and why. Real-time systems experience at consumer scale. Several years of managing engineers, with hiring and firing calls you'd defend in detail. Total headcount matters less to us than the calibre and the outcomes. Based in London. We sponsor visas: you don't need to be in the UK today, you just need to be willing to move. Regular travel to our Cyprus hub expected, especially early on. What we offer Office-based role in West London, four days a week with flexible start and finish times, plus one remote day of your choice Employee stock options plan Private medical and dental insurance Life and critical illness cover Latest-generation MacBook Pro and 4k display Monthly credit towards Wheely journeys Cycle to Work scheme Professional development stipend Relocation support, including visa sponsorship and allowance All of your personal information will be collected stored and processed in accordance with Wheely’s Candidate Privacy Notice
