Senior Fullstackutvikler - 8+ års erfaring - Oslo

Senior Product / Full Stack Developer

Klingit

The Role​ We're looking for a Senior Product / Full Stack Developer​ to join our small, tight-knit team. You'll work closely with our CTO, building features that directly solve real business problems. This is hands-on development where you'll own decisions, ship code regularly, and take pride in pragmatic solutions. You'll have significant autonomy, real impact on product direction, and the satisfaction of seeing your work used by clients and colleagues every day. What We're Building​ Our platform uses a modern, pragmatic stack: • Backend​: Go monolith with server-side rendering and Turbo (Hotwired) for HTML-over-the-wire interactions • Legacy systems​: Ruby on Rails app with two Vue frontends (Client and Backoffice) being thoughtfully retired • Infrastructure​: PostgreSQL for all data, Metabase for analytics, self-hosted on DigitalOcean VPSs orchestrated with Docker and Docker Compose • Operations​: Minimal overhead, maximum reliability; we favor stability over speed We use AI strategically to accelerate development, but the code is ours to own, understand, and trust. We automate what makes sense and avoid complexity that doesn't fit in our heads. Your Responsibilities​ • Develop features in our Go backend and contribute to the gradual migration away from Rails • Write clear, efficient SQL queries and collaborate on data modelling without relying on ORMs. • Write frontend code that's simple, maintainable, and effective (Turbo and Stimulus, or Vue.js if appropriate) • Own technical decisions within our pragmatic constraints, and be willing to revisit them as a team • Think deeply about data models and business problems, not just technical purity • Help maintain and improve our Docker-based infrastructure • Collaborate closely with the CTO on prioritization, architecture, and problem-solving What We're Looking For​ You're a pragmatic thinker who enjoys writing software to solve real business problems. You value simplicity​ and stability over perfect architectures and can make autonomous decisions while staying aligned with team direction and business needs. Hard requirements​ • You genuinely enjoy typed languages.​ You understand the value of type safety and actively choose it, even in languages that don't enforce it (using tools like Beartype in Python, Sorbet in Ruby, TypeScript for JavaScript). Types aren't a constraint you tolerate; they're a tool you appreciate. • You understand Docker.​ You don't need to be an expert, but you appreciate its benefits (reproducibility, consistency, isolation) and understand its trade-offs. You can reason about containers, images, and Compose setups without excessive hand-holding. • You are comfortable writing SQL by hand.​ You can design queries, reason about performance, and debug issues directly in SQL. We do not use ORMs; we embrace SQL as our primary interface to the data. Nice to have​ • Experience with Go or a strong willingness to learn it quickly • Familiarity with Vue.js, React, Angular, or any other frontend reactivity framework • Understanding of server-side rendering or Turbo Wire / HTMX patterns • Experience with PostgreSQL or other relational databases • Comfort with command-line tools and Linux • Experience in small teams where you wear multiple hats What We Offer​ • Real​ autonomy on a small team with meaningful impact • Focused​ work on business-critical systems without unnecessary complexity • Stability​ through pragmatic decision-making and deliberate tech choices • Growth​ opportunities to influence product strategy and architecture • The chance to build something lasting​ that clients and colleagues rely on every day The Interview Process​ We keep the process straightforward and focused on how you think: • Initial conversation about your background and what excites you • Including a technical discussion about how you approach problems (no trick questions) • Working session or take-home exercise aligned with real work • Final interview • Offer How to Apply​ Send us: • Your CV or LinkedIn profile • A brief note on why you're interested in this role • Include links to any work you're proud of (GitHub, portfolio, etc.), or a short description of a recent project We're hiring now and will move quickly for the right fit. Why join Klingit?​ At Klingit, good quality design and development is seen as a key driver of success in any business, and we are driven by creating more equal opportunities for creatives all over the world. By joining Klingit, you will be part of the journey to create something new in the agency world and have the chance to make a real impact.

Senior Software Engineer (Rust)

Six Robotics

About Six Robotics​ At Six Robotics, we build intelligent software that gives Unmanned Aerial Vehicles (UAVs) the ability to collaborate, adapt on the fly, and execute missions that were previously impossible. From our base in Oslo, our 50+ experts in defence, software, and AI develop Valkyrie, our flagship autonomy and swarm platform used by both government and industry. In close partnership with the Norwegian Defence Research Establishment (FFI), we move fast from concept to live deployment, often in the field alongside end users. We work with advanced hardware and software, a modern tech stack, and missions that demand both technical mastery and operational discipline. Everyone is close to the action, from deep technical problem-solving to field operations. We move fast and value clarity, integrity, and teamwork in everything we do. At Six Robotics, every person executes with precision, adapts to changing conditions, and strengthens the team. Getting in is hard, and you’ll be challenged every day. But if you have the skill, the discipline, and the drive to push your limits and always be sharpening your blade, you’ll find no better place to deliver real-world impact while collaborating and learning from the best in the field. About The Role​ We are hiring both Software Engineers and Senior Software Engineers who will work primarily in Rust​ to strengthen and scale the backend of our Ground Control Station (GCS) – the system used by drone operators to plan, monitor, and control missions. This role is appealing if you are excited about Rust as a modern systems language and want to help shape how it is used in a real-world, production-critical environment. We want to increase competence, raise the engineering bar, and build a robust Rust ecosystem internally. However, the primary goal is not to “write Rust for Rust’s sake.” The goal is to build reliable backend systems, APIs, and integrations that operators depend on. Rust is the tool. Solid engineering is the mission. You will join Grounded, the team that builds and maintains the backend powering our Ground Control Station. This includes developing the APIs used for interfacing with edge devices (drones), frontends (UI), integrating with third-party systems (BMS) and telemetry platforms. Being part of the Grounded team you are building the hub that connects multiple parts of the product into one coherent system. After six months in the role, success means you have shipped one or more substantial features to production and taken ownership of parts of the backend. You have improved system quality and influenced architectural decisions, while also helping raise the bar for how we use Rust internally, contributing to stronger practices, patterns, and technical direction. What You Will Do​ • Develop and extend backend features for the Ground Control Station (GCS) • Design and implement APIs for edge, frontend, and external integrations • Interface with third-party systems and services • Improve Rust tooling, conventions, and best practices within the team • Contribute to a gradual and pragmatic transition from C++ to Rust where appropriate • Contribute to backend authentication and security What we are looking for​ We are looking for Software Engineers with a strong engineering mindset who care deeply about system quality, structure, and long-term maintainability. You take pride not only in writing clean and robust code, but in improving the product as a whole. You think about how your technical decisions translate into value for real end users, and you are motivated by building systems that operate reliably in critical, real-world contexts where performance, correctness, and usability truly matter. You may already have solid Rust experience, or you may come from C++/Go or another systems/backend background with a strong interest in Rust. What matters most is that you understand quality backend systems at scale, think holistically, and write code that by default is maintainable and robust. You are motivated by quality and ownership. You want to improve systems, not just complete tasks. You care about architecture, robustness, and correctness, and you are comfortable contributing to technical direction as well as implementation. We believe the right candidate brings​ • 2+ years (5+ years for senior level) of professional software engineering experience, with a strong engineering and quality mindset focused on building robust, production-grade systems rather than prototypes. • Professional experience with Rust, or strong experience in an adjacent systems/backend language (such as C++ or Go) combined with recent hands-on Rust development • Solid backend or systems development experience • Strong Linux fundamentals • Highly efficient and structured technical communication skills, expressing decisions and trade-offs in a clear manner • Fluent in English (Norwegian not required) Nice-to-haves:​ • Experience from adjacent systems and backend technologies such as C++ or Go • Experience building server/cloud-based systems • Experience designing and maintaining APIs • Experience with Geographic Information Systems (GIS) • Exposure to advanced network configuration, video pipelines, or infrastructure environments involving Kubernetes and cloud deployment. • Having built asynchronous services or gRPC-based systems using Protobuf in a microservices architecture. Experience working with distributed systems and service-to-service communication would be valuable for this role Why You Should Join​ At Six Robotics, we're not just building software - we're redefining how unmanned systems operate in the real world. If you're driven by meaningful problems, technical depth, and the chance to shape something from the ground up, you'll find your place here. • Work on problems that matter​ Our technology helps unlock smarter, safer, and more adaptable UAV operations in defense and industry, solving real challenges with direct, tangible impact. • Lead the shift in a hardware-dominated space​ We're bringing modern AI, autonomy, and scalable software into a field that's long relied on rigid, pre-programmed systems, to change how UAVs are designed, deployed, and managed. • Build from zero, shape the future​ Join early and help define the core systems, tools, and culture of a company that’s still being built - where your ideas, code, and decisions will have a lasting influence. • Work with purpose, supported by great benefits​ You'll be part of a mission-driven team that values clarity, integrity, and collaboration, offering competitive pay, equity potential, strong insurance and pension plans, and ongoing learning opportunities. Our Recruitment Process​ • Screening interview with one of our recruiters to get to know you better (30 min). • Meet & Greet with someone from the team to learn more about us (60 min). • Programming assignment to be solved in your own time, followed by a technical interview (90 min). • Final interview with our CTO and Head of People (45 min) Reference check followed by an offer if everything goes well. We consider applications continuously, so don’t hold off with applying if this looks interesting. Our Commitment to Inclusion​ At Six Robotics, we are committed to creating a workplace built on respect, integrity, and collaboration. We value different perspectives and experiences, and we believe that diversity within our team strengthens both our work and our culture. We encourage all qualified candidates to apply and help us build technology that makes a real impact. Security Clearance Requirement​ All employees at Six Robotics are required to undergo a security clearance due to our close collaboration with the Norwegian Armed Forces. While prior clearance is not necessary, the clearance process will be initiated as part of onboarding.
