Go is what you'd write day to day, but we care more about the fundamentals than the language: strong backgrounds in other statically typed languages are welcome. * Comfortable on Linux, with an understanding of the OS your software runs on (processes, networking basics, packaging, systemd), even if you're not a systems engineer. * Solid grasp of build systems, CI/CD, and release pipelines. You've worked in a monorepo or a serious build/release setup and made it better. * A track record of delivering: shipping, closing out, and not letting scope or polish stall a deliverable. * Good written and verbal communication, and the collaborative instinct to treat non-developer engineers as first-class colleagues. Desirable attributes Things we'd like to see. You won't have all of them, and that's fine. * Interest or hands-on experience in developer experience and AI/coding-assistant tooling. Building or integrating LLMs into a real engineering workflow is a plus, but curiosity about how these tools change work practices counts too. * Experience with infrastructure/platform software: inventory/asset systems, monitoring, alerting, scheduling, container orchestration or similar backend platform work. * APIs, data pipelines and schema management: designing clean service APIs and moving data between systems reliably. * Infrastructure-as-code and cloud fluency. We use Terraform and AWS as required, but experience with Azure or GCP is just as relevant. * Exposure to server or network hardware, networking concepts, or datacentre operations. ## Description Shared Engineering is a mixed-discipline platform team of around a dozen engineers (network engineers, Linux engineers, and software developers). The team owns the foundations that the firm's engineering runs on such as alerting, job scheduling, host inventory/monitoring, and the internal developer tooling for our monorepo. This includes shared libraries, build systems and CI/CD infrastructure. Our aim is to give the firm's engineers leverage: fewer manual steps, delivery that is fast and predictable, and teams who can self-serve rather than raising a ticket and waiting. We have many initiatives in flight at once, so judgement about which thing to work on matters nearly as much as building it well. This is a software-developer role on the team focused on developer experience and platform software: building the tools, services, and libraries that make everyone else's engineering faster and more reliable. A growing part of that remit is how the firm's engineers adopt AI and coding-assistant tooling. Recent work includes our self-service network configuration tools, sandboxing and gateway services for coding assistants, and pulling host inventory data into a single source of truth. Responsibilities * Working primarily in Go, build and own platform services and internal tooling end-to-end, from design through to production. * Improve developer experience by reducing friction in the build/CI/CD path, strengthen shared libraries. * Help shape how the wider firm adopts AI/coding-assistant tooling safely and effectively, integrating it into workflows and building guardrails and tooling around it. * Collaborate with the network and Linux engineers to understand what the infrastructure needs in order to scale and be managed, then expose it cleanly in software. * Mentor and share knowledge, improving teammates' skills and making sure others can maintain and build on the systems you develop. * Review and raise standards by thoughtful code review, sensible judgement on where to block versus where to let things flow, and a pragmatic sense of the right work to be doing right now. * Take part in on-call once up-to-speed, troubleshooting problems that span several technical domains across current and legacy infrastructure. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Infrastructure as Code: The Developer's Secret Weapon](https://www.wearedevelopers.com/videos/1221-infrastructure-as-code-the-developer-s-secret-weapon) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Navigating the Future of Junior Developers in Tech](https://www.wearedevelopers.com/videos/1280-navigating-the-future-of-junior-developers-in-tech) ## Related Articles - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
