Polatis is a leader in all-optical network switching technology, delivering cutting-edge solutions to global customers.
Our Product Software Team develops customer-facing software for our industry-leading optical switches, managing two distinct software stacks:
• Network Software (NIC SW): Implements L2/L3 protocols and interfaces (TL1, Netconf, Restconf, WebUI).
• Control Software (DSP SW): Bare-metal stack controlling piezoelectric actuators for precision optical switching.
We are seeking a Senior DevOps Engineer to define and lead our DevOps strategy across embedded Linux and bare-metal firmware environments.
You will design scalable CI/CD pipelines, automate build and test workflows, and integrate modern DevOps practices to accelerate development cycles and improve product quality.
This is a key role bridging embedded systems with advanced automation.
Key Responsibilities of the Senior DevOps Engineer role:
• Design, implement, and maintain CI/CD pipelines for Yocto-based Linux and bare-metal firmware projects.
• Automate build, test, and deployment processes, including hardware-in-the-loop (HIL) testing.
• Integrate static analysis, unit testing, and monitoring into automated workflows.
• Manage and optimize build infrastructure using Jenkins, GitLab CI, and custom scripts.
• Ensure reproducible Linux builds with Yocto, including kernel and BSP layer maintenance.
• Develop containerized environments (Docker) for consistent build and test processes.
• Collaborate with development, QA, and IT teams to embed DevOps best practices across the organization.
• Promote automation and infrastructure-as-code principles to improve efficiency and scalability.
• Implement secure DevOps practices, including credential management and artifact signing.
• Support compliance standards (e.g., ISO 26262, IEC 62304) through traceable, audit-ready pipelines.
In order to be successful in this role you must have:
• Proven experience with CI/CD for embedded Linux (Yocto) and bare-metal systems.
• Expertise in cross-compilation toolchains, linker scripts, and bootloader integration.
• Strong Python and shell scripting skills for automation.
• Hands-on experience with secure code signing and HSM integration.
• Familiarity with hardware-oriented test automation (flashing, UART, board resets).
• Proficient in Jenkins, GitLab CI, and containerization (Docker).
It would be great if you had:
• Knowledge of Kubernetes for scalable test environments.
• Exposure to cloud platforms (AWS, Azure, GCP) for CI/CD and remote testing.
• Experience with security and performance testing tools (Nessus, JMeter, Locust).

How to Write a Cloud Computing Job Ad That Attracts the Right People

Cloud computing underpins much of the UK’s digital economy. From startups and scale-ups to enterprise organisations and the public sector, cloud platforms enable everything from data analytics and AI to cybersecurity, DevOps and digital services. Yet despite high demand for cloud skills, many employers struggle to attract the right candidates. Cloud job adverts are often flooded with unsuitable applications, while experienced cloud engineers, architects and platform specialists quietly pass them by. In most cases, the problem is not the shortage of cloud talent — it is the quality and clarity of the job advert. Cloud professionals are pragmatic, technically experienced and highly selective. A poorly written job ad signals confusion, unrealistic expectations or a lack of cloud maturity. A well-written one signals credibility, good engineering culture and long-term thinking. This guide explains how to write a cloud computing job ad that attracts the right people, improves applicant quality and strengthens your employer brand.

Maths for Cloud Jobs: The Only Topics You Actually Need (& How to Learn Them)

If you are applying for cloud computing jobs in the UK you might have noticed something frustrating: job descriptions rarely ask for “maths” directly yet interviews often drift into capacity, performance, reliability, cost or security trade-offs that are maths in practice. The good news is you do not need degree-level theory to be job-ready. For most roles like Cloud Engineer, DevOps Engineer, Platform Engineer, SRE, Cloud Architect, FinOps Analyst or Cloud Security Engineer you keep coming back to a small set of practical skills: Units, rates & back-of-the-envelope estimation (requests per second, throughput, latency, storage growth) Statistics for reliability & observability (percentiles, error rates, SLOs, error budgets) Capacity planning & queueing intuition (utilisation, saturation, Little’s Law) Cost modelling & optimisation (right-sizing, break-even thinking, cost per transaction) Trade-off reasoning under constraints (performance vs cost vs reliability) This guide explains exactly what to learn plus a 6-week plan & portfolio projects you can publish to prove it.

Neurodiversity in Cloud Computing Careers: Turning Different Thinking into a Superpower

Cloud computing sits at the heart of modern tech. Almost every digital product runs on someone’s cloud platform – from banking apps & streaming services to AI tools & online shops. Behind those platforms are teams of cloud engineers, architects, SREs, security specialists & more. These roles demand problem-solvers who can think in systems, spot patterns, stay calm under pressure & imagine better ways to build & run infrastructure. That makes cloud computing a natural fit for many neurodivergent people – including those with ADHD, autism & dyslexia. If you are neurodivergent & considering a cloud career, you might have heard messages like “you’re too distracted for engineering”, “too literal for stakeholder work” or “too disorganised for operations”. In reality, many traits that come with ADHD, autism & dyslexia are exactly what cloud teams need. This guide is written for cloud computing job seekers in the UK. We will cover: What neurodiversity means in a cloud context How ADHD, autism & dyslexia strengths map to cloud roles Practical workplace adjustments you can ask for under UK law How to talk about neurodivergence in applications & interviews By the end, you should have a clearer sense of where you might thrive in cloud computing – & how to turn “different thinking” into a professional superpower.
