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.

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?
