Senior Backend Software Engineer

About Us At No Isolation, we’re a profitable, 65-person Norwegian EdTech scale-up operating across Europe. We help educators bring learning and belonging to every child. Our AV1 robot is deployed in 19 countries, with 5,000+ units supporting schools to improve attendance, belonging, and continuity of learning for children who cannot be physically present. Consistently described as life-changing, it bridges the gap between the student and their peers, restoring both educational continuity and the essential sense of social belonging. We’re established enough to have a proven solution and strong financial foundations, yet still small enough for every new colleague to have a visible impact on our next stage of growth. The Opportunity — Software Engineering (Backend) Join us to build the core systems that enable thousands of children through the AV1 robot. As a Software Engineer proficient in Golang, you will be at the intersection of complex, real-time technical challenges. Our solutions are scaling across continents, and we need your expertise to improve existing services and implement novel features. The backend you will co-own and further develop supports real-time communication between our fleet of robots, mobile apps, and web clients. You will be engineering high-performance systems to handle live video, audio, events, and last but not least, massive data collection to enable new customer value through our growing unique proprietary dataset. You will design, build, and evolve the APIs, services, modules and system integrations that are vital to our ecosystem. You will be entrusted to make critical architectural decisions, model data for correctness and scale, and engineer for resilience. You will enjoy the focus on writing well-instrumented code and will get the chance to further raise the bar for how we design and operate our systems to deliver reliable, life-changing experiences for the children and schools we serve. What You’ll Do — Scope & Responsibilities Backend systems design & implementation Design and implement backend APIs and shared modules, primarily in Golang, that connect robots, mobile apps, web clients, and cloud servicesSelect and configure the right paradigms for the job, including WebRTC, gRPC, web sockets, REST, and newer technologiesDevelop data models, schemas, and safe up/down migrations across relational, NoSQL, and analytical storesDesign container-based, event-driven services and asynchronous processing pipelines that handle real-world usage patternsAlign on system design and architecture in collaboration with peers, and maintain clear troubleshooting runbooksEmbrace both unit and end-to-end testing so we ship confidentlyCollaborate closely with frontend/mobile, platform, and embedded teams to shape APIs, contracts, and integration patternsTeam collaboration & enablement Role-model AI tooling adoption (e.g., Claude Code, custom agents) to accelerate backend engineering in a safe, deliberate wayContribute to developer experience by refining tooling, local dev environments, and shared libraries for backend workDocument key flows, patterns, and decisions so others can self-serve and move faster with confidenceSupport internal stakeholders with data and internal tools that reduce 3rd-line support load and improve incident handlingHelp evolve our data pipelines and assets for analytics, user insights, and future predictive modellingOperational security and reliability Instrument backend services with top observability standardsCollaborate with Platform Engineering on container deployment and orchestration (Kubernetes, Terraform)Build for correctness, durability, resilience, and performance by design, not as an afterthoughtParticipate in incident response, debugging, and post-incident reviewsEmbed secure coding practices throughout the development lifecycle, from design reviews to code reviews and rolloutApply robust AuthN/AuthZ patterns, encryption, data-integrity controls, and secure service-to-service communication What You Bring — Experience & Capabilities Backend engineering: Experience in Go (Golang), API design, backend architecture, and distributed systems. You have implemented services using e.g. WebRTC, gRPC, sockets, REST, and other web protocols. You can strike trade-offs between cost and performanceOperational familiarity: Proven experience with AWS services or other cloud providers. You have been hands-on with the likes of Sentry and Grafana. You are comfortable with some exposure to Terraform and KubernetesData & storage competence: Solid experience with relational, NoSQL, OLAP databases and caches (e.g. MySQL, MongoDB, ClickHouse, Redis). You know how to model data, optimize queries, tune performance, and design for failover and recoverySecurity & quality mindset: You build systems that are correct, predictable, secure, and maintainable. You inform key security aspects such as proper secrets handling, encryption standards, rate limiting and vulnerability managementTechnical collaboration: Clear, direct communication, with empathy when working with frontend/mobile, embedded, platform, and non-technical peers. You are comfortable leading technical discussions, and are able to change your mind in light of new evidenceTechnical education and experience: Higher education in a STEM field (BSc/MSc)Product experience: You have worked at product companies before, ideally across multiple stacks or domains Why You'll Love it Here Purpose with scale: Your work keeps thousands of children connected, learning, and included every single dayReal systems, real impact: From fleets of robots to real-time apps, you will tackle backend and reliability challenges that matter in the physical world, not just on a dashboardAutonomous ownership: As a key Software Engineer in a small, tight-knit cross-functional engineering team, you will shape our backend domainWork with exceptional leaders: Build, learn, and grow alongside our Director of Engineering (Jerome Ginss) to shape a high-trust, learning-driven engineering culture, and impact KPIs valued by the executive teamGrow your craft: Elevate your skills in a lean, fast environment, with freedom to pitch in what you assess to be best practices27 days of holidayFlexible working around core hours (10:00-15:00)Mobile phone and Internet subscriptionRegular company socials and an annual trip away together Our Tech Stack Think container services, mobile apps, multiple web apps, and fleets of connected robots. It’s a rapidly growing ecosystem, wired by WebRTC, web sockets, Rest APIs and more. We pride ourselves with a choice of modern and exciting, yet battle-tested technologies. We balance hosting versus buying core systems pragmatically. Languages & frameworks: Golang, React, React Native, Rust (Embassy), PythonCloud & Infrastructure: AWS, Kubernetes, Traefik, Terraform, AnsibleObservability: Grafana stack, PrometheusDevelopment: GitLab, Sentry, Linear, OhDearPlatforms: Linux, Android, iOS, our custom Yocto distributionsData & Analytics: MySQL, MongoDB, ClickHouse, Redis, Metabase Location This role is based in Oslo with hybrid flexibility at our headquarters (minimum 2-3 days in-office/week). We welcome all qualified applicants. Due to current visa/work-permit processes, we can progress candidates already in Norway or relocating from within the EU/EEA (with no need for additional work permit).
