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

For more information on what it’s like to be a Healios employee, and our hiring processes, take a look at our Notion page.  “Great minds don’t think alike”  From our talented tech teams to our standout clinical expertise, we are bringing great minds together to build more accessible services. Our software supports clinicians, young people and families through some of the most important moments of their lives, so it needs to be reliable, secure and built with care.   Our values Our values shape how we build, collaborate and care for everyone we support.

We work in a focused, remote environment that values small, collaborative teams, clear ownership and the space to do your best work without unnecessary meetings or noise. Your work will contribute to one of our three strategic areas: improving the experience of the clinicians who use our platform, making client operations sustainable as we grow, or giving our partners the confidence to expand their work with us. You’re a full-stack generalist who is growing into ownership. You like to take features end-to-end, you’re comfortable with ambiguity and finding your own answers, and you keep your team informed without being chased.

You’ll work closely with engineers, analysts and tech associates to shape, build and ship features that are simple, scalable and useful. Specialisms Some engineers hold a specialism based on team needs, usually around 20% of their time. It is a chance to grow domain knowledge and take on a key responsibility. Options include infrastructure (shared tooling, environments and deployment), data insights, front-end and the design system, or engineering response.

Mirelo

Mirelo AI is building the next generation of creative tools by generating realistic sound, speech and music from video. We develop cutting-edge foundational generative AI models that "unmute" silent video content and create custom, hyper-realistic audio for gaming, video platforms, and creators. Our technology empowers global storytellers to transform their content. We recently closed a $41 million Seed round co-led by Andreessen Horowitz and Index Ventures with participation from Atlantic, and are rapidly expanding across Product, Engineering, Go-to-Market, and Growth. About the Role At Mirelo, you’ll join a small, fast-moving team building real products on top of our generative audio models. This role is hands-on and high-ownership: you’ll ship end-to-end features across our stack, work directly with research and product, and help shape how our technology becomes something creators and partners actually use. As we scale our go-to-market efforts, the engineering work you do will sit at the heart of both user-facing products and deeper integrations with platforms, tools, and enterprise partners. Key Responsibilities * Building and maintaining our products on top of our cutting-edge generative AI models for music and sound. * High degrees of ownership: you will be responsible for shipping end-to-end features across the front and back ends of our stack, as well as helping set the direction of the features and products you're working on. * Collaborate closely with our research teams and growth/sales teams and stay close to our users: spot practical opportunities, identify pain points, and turn them into actionable engineering tasks. * Work comfortably with our current tech stack: TypeScript, React, Tailwind, shadcn, and Convex as the backend. * Work with essential cloud services—primarily AWS Lambda and S3—for integrations, automation, and deployment workflows * Use modern AI-assisted development tools (Cursor, Claude Code, etc.) to move fast while keeping craftsmanship high. * Communicate clearly with teammates, jump into discussions, and help drive the technical direction together. Ideal Candidate Profile * 5+ years of professional web development experience, preferably in fast-moving product or startup environments. * Strong expertise in TypeScript (both frontend and backend), React, Tailwind, component libraries. * Solid understanding of backend fundamentals: data modeling, migrations, performance, API design, security and data workflow. * Self-directed in a healthy way: you take ownership, move forward proactively, and keep the team in the loop. Nice to Have * Basic understanding of machine learning and experience using ML/LLM tooling in products. * Hands-on experience with Convex, or similar serverless backend platforms, and the ability to quickly become productive with it. Proficiency in Python. * Exposure to AWS beyond Lambda/S3 (CloudFront, IAM basics, monitoring). * Experience contributing to or maintaining larger production codebases. WHY JOIN? * Join at a pivotal moment. We've secured fresh funding and are gaining traction - now is when your contributions can make a real difference to our success. * True ownership from day one. You'll have genuine autonomy and responsibility. Your ideas and work will directly shape our product and company direction. * Competitive compensation and equity. We offer strong packages that ensure you share in the success you help create. * Build for the next generation of creators. Be part of the innovation that will transform how creators work and thrive. We welcome applications from all individuals, regardless of ethnic origin, gender, disability, religion or belief, age, or sexual orientation and identity.
