Senior Backend Developer/Engineer/AI-Something - App 📱

Voi Technology

YOUR MISSION AT VOI As an Engineering Manager at Voi, you will lead and grow a cross-functional product team while staying close to the code. This role is ideal for a strong technical lead ready to take a first step into people management – someone who wants to shape team culture, support engineers’ growth, and drive delivery without leaving their technical roots behind. The Monetisation team owns Voi’s core payment flows, subscriptions, upsell and in-app advertising. The technical scope spans core backend systems, payment integrations, native mobile client views and more. This is an excellent opportunity to grow into leadership while having a tangible impact on the micromobility industry. * Be a present, hands-on leader for a team of 4–5 engineers: run 1:1s, support growth and create a safe, collaborative environment where people do their best work. * Partner closely with the Product Manager and Designer to align on priorities, shape the roadmap and drive high-quality delivery. * Lead by doing: write code, review PRs and engage deeply in technical decisions across backend, web and mobile. * Champion engineering excellence by guiding architectural decisions, fostering good development practices and promoting continuous improvement – enabling sustainably rapid delivery in a complex micromobility business. * Coach and develop engineers through feedback, mentorship and clear expectations – with support from us if this is your first formal people management role. * Lead the team in adopting agentic engineering practices: actively use and encourage AI-assisted development and help engineers build the habits and judgement to get the most out of these tools. * Contribute to a collaborative engineering culture aligned with Voi’s values, and be a driver for inclusion and psychological safety within your team. WHAT YOU NEED TO EMBARK You are a hands-on, collaborative engineer with a passion for both technology and people. You enjoy working across domains, take ownership of delivery and are curious about how AI can elevate the way teams build software. * 4+ years of hands-on experience as an engineer in modern tech stacks, building reliable software in a fast-paced environment. * A generalist mindset with experience in backend, web and/or mobile development. * 2+ years of experience in a tech lead, senior or informal leadership capacity – you have guided others technically, even if you have not held a management title. * No prior people management experience required – this is a growth area we will support you in. * Practical experience with AI-assisted development tools (for example modern code assistants) and a genuine interest in agentic engineering workflows. You lean into these tools and help your team build the skillset to use them effectively. * Strong communication skills and the ability to navigate both technical and cross-functional conversations with ease. * Fluency in English, written and spoken. Don’t meet every requirement? If you are excited about this role and our mission, and have relevant, transferable skills, we encourage you to apply – even if you don’t check every box. WHY VOI? Working at Voi is more than just a job; our People Promise includes a personal voyage where you will grow as a professional and be a part of a team and culture that builds something meaningful for society. In addition to this you’ll have the opportunity to: * Join Europe’s #1 micromobility operator and one of the fastest growing scale-ups. * Get “skin in the game” through our employee options programme. * Enjoy unlimited free Voi rides and a dog-friendly office. * Work together with inspiring, motivated and fun colleagues towards a common goal. * Join the micromobility revolution and be a part of creating sustainable cities made for living, free from noise and pollution.

Anyfin

Anyfin is building the next generation of consumer finance. We’re profitable, scaling quickly and now operating with a banking license which opens up a lot of technical complexity. We’re looking for a senior react native engineer who enjoys moving fast, taking real ownership and building things that actually have an impact. We work from the office because we think it makes us better, especially at this stage. If that sounds like your kind of environment, keep reading. Because honestly, it’s not a role for everyone. SMALL TEAM, HIGH RESPONSIBILITY We hire carefully. We’re not a company that grows by adding headcount everywhere, we grow by keeping the bar high and building a team where every person matters. This isn’t a place where you disappear into a big org. If you join, you’ll have real influence on what we build and how we build it. WHAT YOU’LL DO You’ll take a leading role in building and evolving our mobile applications across iOS and Android. * Building and shipping new mobile features in React Native. * Designing reusable components and scalable mobile architecture. * Collaborating closely with design to deliver polished, accessible user interfaces. * Integrating with our GraphQL APIs to power seamless user experiences. * Making architectural decisions that improve performance, maintainability and developer experience. * Running experiments and iterating on features to improve user engagement and retention. * Writing and maintaining automated tests to ensure reliability across releases. * Mentoring other engineers and helping raise the bar for mobile development. Tech stack: Mobile: React Native, TypeScript, Apollo Client (GraphQL) Backend you'll work closely with: Node.js/Express, GraphQL Federation, PostgreSQL, Redis Infrastructure: GCP, Kubernetes, GitHub Actions Product tooling: Storybook, GrowthBook HOW WE THINK ABOUT BUILDING We’re pragmatic. We like speed, but we also care about building things that last. AI is already part of how we build and not an aspiration. We use Claude, OpenAI, and Mistral in our product, and we expect our engineers to actively explore how AI tooling removes friction from day-to-day work: in code review, test writing, and prototyping. We're looking for someone who sees AI as an amplifier of craftsmanship and not a substitute for it. No ego. Just good judgment and high output. YOU’LL THRIVE HERE IF YOU… * Have strong experience building mobile apps with React Native. * Care about craftsmanship, performance and user experience. * Take responsibility naturally and don’t wait to be told what to do. * Enjoy collaborating closely with design and product. * Like being part of an ambitious team working together in the office. * Want to build and improve products, not just maintain them. You’re comfortable with things like: * React Native and modern TypeScript-based development. * Mobile architecture and reusable component design. * API integrations (GraphQL or REST). * Testing strategies for mobile applications. * Shipping real products to real users. A FEW PRACTICAL NOTES Stockholm and we're office-based, because we believe that great products and culture are better built when you meet in person. There is flexibility of course, but you should want to work on site with the rest of us most days of the week. WHY ANYFIN? Because this is one of those moments where a company is about to level up: Banking license secured, expansion ahead and a lot to build. If you want to be part of a small, high-trust team doing meaningful work, we’d love to hear from you. Apply only if you want the responsibility that comes with real impact.
