Full Stack Software Engineer

Ameba

Full-Stack Software Engineer at Ameba Engineering at Ameba is a rare opportunity to build cutting-edge software in a traditional industry, while being generously rewarded for your contributions. If you’ve never considered working in supply chains before, everything around you, including the device you're reading this on, has a story of how it got there. Raw material to finished product, that story is the supply chain. If the unseen machinery of the world sparks something in you, we'd love to talk! We're a startup made up of experienced entrepreneurs (who have previously raised $160m+) and builders (ex-Meta, Palantir, Microsoft, Quant Devs, UnlikelyAI). We have big ambitions and are backed by some of the most successful investors in Europe. We’ve raised over $9M since our launch just over a year ago. Your Role as a Full-Stack Engineer As a Full-Stack Engineer, you will collaborate closely with our CTO and engineering team to design, build, and launch products from conception to launch. This involves working across the entire stack — from front-end (written in React/TypeScript), back-end (written in Kotlin and Python), machine learning (agentic workflows, entity matching), to infrastructure (AWS, Docker). Working at a startup so early, it's common to kick off a feature on Monday, and have users use it on Friday. You should be comfortable working with these tight feedback loops and long to build a product that users love. Don't worry if you lack experience in any of these areas - your application is still welcome! Life at Ameba We pride ourselves on providing top-of-market salaries and generous equity packages to all employees. We're assembling a lean team of exceptionally talented individuals and aim to reward them accordingly. * We enjoy collaborating together in the office, typically five days a week, for easy, high-bandwidth conversations. While we provide flexibility to work from home when necessary, our primary focus at this early stage is creating a strong office-first experience. * We offer 28 holiday days per year, and we shut down entirely over the holiday season for 2 weeks, allowing everyone to disconnect completely. * We provide four months of maternity and paternity leave at 100% salary. * We offer comprehensive healthcare and dental cover. * The salary range for this role is £80,000-£130,000 + generous equity. The salary for this position is determined by several factors, such as experience, relevant skills, business needs, or market demands. * You will have the opportunity (if you want it) to visit customers at their place of work, both in the UK and outside it! We currently work with customers in Portugal, the Netherlands, and more. Qualifications Essential: * Minimum 3 years of experience as a software engineer. * 2+ years of experience with React/TypeScript and an Object-Oriented Programming Language (Java, Scala, Kotlin, C#, C++). * Proven experience in building and shipping software, involving collaboration with other engineers, designers, product managers, and users to identify and implement solutions based on customer needs. * 1+ years of experience contributing to the system design or architecture (architecture, design patterns, reliability and scaling) of new and existing systems. Desirable: * Undergraduate or Masters degree in Computer Science (or related fields). * Experience with AWS and Docker. * Interest in AI, and familiarity with building LLM-based agents. * Exposure to contract-first development (OpenAPI, gRPC/Protocol Buffers). * Ability to design scalable and efficient system architectures. * Ability to navigate rapidly changing priorities in a growing startup environment. * [Optional] Previous experience working at a startup or a keen interest in startups

WHAT YOU'LL BRING * Experience building and shipping production-quality software. * Strong TypeScript / JavaScript skills and significant frontend experience in production codebases. * Solid experience with React and modern frontend tooling (such as Tailwind). * Comfort collaborating with designers in Figma (or similar tools) and translating designs into accessible, responsive UI. * A user-centric mindset and a genuine interest in product UX, not just shipping components. * Experience creating API services in Golang, Java or Python BONUS POINTS * Experience working with Spotify’s Backstage framework. * Familiarity with graph data, graph algorithms, or data-science workflows. * Experience with Python-based UI tooling such as Streamlit and AnyWidget. * Experience with Snowflake, Snowpark, and building UIs that run inside a Snowflake Native App. #LI-Hybrid Why Join Neo4j?
