Junior Backend Software Engineer. London About Antare Join Antare as we go to market. We’ve been busy building the physical security intelligence platform of the future. Our always-connected platform automatically detects risks, captures evidence and reports on real-world events as they happen, delivering intelligent insights through an intuitive user interface, all hosted in the cloud. Our product is designed so commercial organisations - including, but not limited to, private security, retail, and hospitality - never miss an incident. The Antare founding team of product designers and engineers have together built companies that have been collectively acquired for billions of dollars: We have a genuine level of success under our belts that you could help to contribute to. Today, we’re a growing, hands-on team spanning product, design, finance, marketing, sales, hardware, and software engineering. What we can offer you This is a rare chance to join the early stages of a startup - where your curiosity, ideas, and input will directly influence the product roadmap. You’ll be working closely with a small, experienced engineering team, building real features in a modern frontend codebase from day one. We care deeply about helping early-career engineers grow fast and with confidence. You’ll benefit from hands-on mentorship, regular feedback, and the chance to pair with engineers who’ve built products at scale. It’s a high-trust, low-ego environment designed to help you accelerate your skills while contributing meaningfully. We’re using modern technology stacks across our infrastructure and frontend, and AI-assisted tooling to move fast and stay focused - and you’ll be an integral part of shaping both the user experience and the engineering foundations as we scale. Role Overview As a Junior Backend Software Engineer, you will be designing and implementing scalable, high-performance infrastructure services, APIs and integrations. You’ll join a small and growing R&D team focused on building ambitious new products from the ground up. You’ll work on real product features, contribute to design and development decisions, and grow your technical skillset by collaborating with a supportive team of experienced engineers. We’re looking for someone who is excited to learn, ready to get stuck in, and is comfortable asking questions. You’ll have space to grow, and we’ll back you with the mentorship and feedback to make it happen. Some of the technologies we use, and day-to-day tasks include developing with: Relational databases (PostgreSQL, MySQL, etc.) OpenSearch DynamoDB S3 Event-driven architectures Third-party API integration Access control and user permissions Implementing APIs used by single-page applications WebSockets Infrastructure as code (AWS CDK, Terraform, etc.) Docker AWS IoT What we’re looking for Circa 2 years of commercial or equivalent experience in a software development role building cloud-driven SAAS products, with a focus on building and maintaining infrastructure and backend services. Full stack experience with other languages and frameworks (e.g. React, Vue, iOS, Android) is a plus, but not required. Familiarity with modern backend frameworks and languages such as Golang, Java, C++, Rust, Python A solid academic background, ideally from a leading University with top marks in either Computer Science or STEM subjects demonstrating a passion for software development, coding and technology. Strong problem-solving skills and ability to work in a fast-paced startup environment. Excellent communication and collaboration abilities. Responsibilities Collaborate with cross-functional teams to define and deliver new features against tight milestones. Optimize code for performance, scale, reliability, and maintainability. Contribute to a culture of continuous improvement. Ideally, you’ll have some experience with one or more of the technologies we use. That said, we don’t expect you to know everything already — we’re happy to support your learning on the job. We believe that diverse perspectives make better products, and we strongly encourage people from underrepresented backgrounds in tech to apply. If you’re unsure whether you meet every requirement, please still reach out - we’d love to hear from you. Why Antare Join Antare in London and contribute to a team that’s creating the next generation of innovative products. We offer a competitive salary, equity options, and healthcare, along with the opportunity to build a product that makes a real impact. While we offer some flexibility, we’re primarily an in-person team (4 days per week) - at this stage of the company, we’ve found that collaboration and ideation happen faster and more naturally when we’re in the same room.
