Head of Software Engineering - Market leading SaaS product (NodeJS/ReactJS)South Yorkshire 2 days per week, 3 remote

Opportunities like this simply do not come around that often.

My industry-leading Technology client have created a newly formed role of Head of Software Engineering to lead, motivate and inspire a team whilst driving their incredibly ambitious tech roadmap.

Their flagship SaaS product is doing well within its industry across the UK and Europe with over 500 customers utilising it. But what I love about it, is that they haven’t even scratched the surface of where they intend to take it. It is continuously evolving as a platform, as they anticipate the delivery of an exciting multi-year road-map as they continue to on-board new customers.

Their CTO feels it is the exactly the right time to bring in a top-notch Head of Software to lead, motivate and inspire their talented Software Engineering team and this is where you come in!

I’m looking for a seasoned, inspirational Tech Leader and one that knows exactly how to get the best out of their people. Alongside leading the team, you will play a key role in the technical execution of their ambitious road-map - defining it accordingly and executing across the business.

Let’s talk tech. So - their highly scalable Flagship product is built mainly around the NodeJS ecosystem and this is the foundation of their applications. It’s well-geared for websites with the React framework on the front-end - all on Azure platform What else? TypeScript, Redux.js, React Hooks, Bootstrap and so much more.

Whilst this is a leadership and strategy focused role, you will have a good appreciation for the tech under your remit
Therefore, you will come from a hands-on JavaScript background using Node or React previously and have led teams of Engineers.

You’ll have exposure to Azure platform but other cloud technologies like AWS will be considered.

Alongside their industry-leading product they’re also piloting new stuff like on AI like chatbot - so there’s plenty of opportunities ahead with newer tech. They’re quite a traditional firm with a flat structure - you’ll work closely with the CTO but also their Head of Product and Head of Ops in relation to overall company strategy.

Mega role, superb product and a fantastic team. The CTO is great, with a real vision of where he wants to take their applications. He has been there since Day One when the application was built from scratch & is super passionate about finding the right person to be part of their evolution!

Awesome package with substantial benefits. You’ll be flexible to visit their South Yorkshire offices twice a week and you can work 3 days remotely

We are looking for an Orchestration Software Engineer to help build and evolve a cutting-edge Infrastructure Automation platform supporting a major UK Defence programme.

You’ll be part of the Infrastructure Automation Engineering Service, designing and delivering robust, scalable automation solutions across complex enterprise environments. Translation: you’ll turn messy, manual, legacy build processes into slick, repeatable, automated deployments. And yes, some of it will fight back.

What You’ll Be Doing

• Designing, developing, and validating infrastructure automation components for the NSoIT(D) platform.

• Writing production-grade automation using:

  • Python 3 (core automation logic)
  • Ansible (deployment)
  • Jenkins (CI/CD & build pipelines)
  • Bash & PowerShell (Linux & Windows automation)

• Reverse-engineering existing applications and manual build processes into fully automated, zero-touch deployments.

• Building automation for server, network, and storage platforms across multiple vendors.

• Creating high-quality technical documentation and design artefacts.

• Supporting system testing and resolving live service issues.

• Working in an Agile delivery environment using JIRA and Confluence.

• Collaborating closely with infrastructure, service management, and security teams.

Essential Skills & Experience

You’ll need at least 12 months’ hands-on experience (within the last 3 years) in most of the following:

• Advanced Python 3 development for production automation.
• Configuration management tools such as Ansible, Puppet, or Chef.

• Large-scale infrastructure environments.
• Troubleshooting complex hardware and software issues.
• Agile development practices.

Plus:

• Strong experience with advanced Python & PowerShell features (Workflows, DSC, Bare Metal Deployment).

• At least one current professional certification, such as:

  • CCNP (or equivalent networking cert)
  • VMware VCP (or equivalent virtualisation cert)
  • RHCE / RHCA (Linux)
  • OCA or formal software development certification

• Excellent communication skills - because automation still involves humans.

• Strong analytical and problem-solving ability.

• Active SC Clearance (mandatory).

• Solid MS Office skills.
