Junior Developer

• Spirax Group, formerly Spirax-Sarco Engineering, is a global
• thermal energy and fluid technology solutions Group that supports industrial
• customers in transitioning to net zero. The Group designs technologies that
• improve the efficiency and safety of critical industrial processes behind
• everyday consumables, while delivering new decarbonisation solutions that
• electrify boilers and other process heating applications.
• Spirax Group consists of three world-leading businesses: Steam
• Thermal Solutions (including Spirax Sarco and Gestra), Electric Thermal
• Solutions, and Watson-Marlow Fluid Technology Solutions, all focused
• on resource efficiency and advancements in global health.
• Headquartered in Cheltenham, UK, Spirax Group is a FTSE 100
• company with 37 manufacturing plants, approximately 10,000 colleagues in 66
• countries, and 110,000 customers worldwide.

About the role

We are looking for

• a Junior Developer to join the team building the cloud platform behind
• our connected industrial products, a production industrial-IoT system that
• ingests telemetry from tens of thousands of sensors in customer plants, decodes
• and enriches it, runs engineering calculations over the resulting time series,
• and serves the results to internal engineering teams and to customers.
• This is a role for
• someone with roughly two to three years of commercial development experience
• who wants to go deeper. You will be writing production code within your first
• few weeks, but you will not be doing it alone: you will pair with senior
• engineers, your work will go through review, and you will be given a route into
• the codebase rather than a sink-or-swim start.

We care more

• about how you think than about how many technologies you have already used. The platform runs on a broad stack, set out below, and we do not expect you to
• arrive knowing all of it. If you are solid in one or two of those areas and
• genuinely keen to learn the rest, we would like to hear from you.

What you will be doing

• Build and maintain backend features in C# /
• .NET or TypeScript, following the patterns already established in the
• codebase, with tests written alongside the code.
• Work on the front end: React and TypeScript
• components and screens, taking a ticket or a design through to a merged
• pull request.
• Help develop the data pipelines that decode
• device telemetry and compute engineering values, starting with well-scoped
• changes and growing into larger pieces of work.
• Write and run automated tests, and treat a
• failing test as useful information rather than an obstacle.
• Take part in code review, as an author and
• as a reviewer. Reading other people’s code is the fastest way to learn a
• platform this size.
• Deploy your own work through our CI/CD
• pipelines, and build up an understanding of how the environments and
• infrastructure fit together.
• Investigate and fix defects in the running
• platform, with a senior engineer alongside you at first and increasingly
• on your own.

Contribute in design discussions and stand-ups

• ask the question you think might be obvious, because it usually is not.
• Keep the documentation honest as you change
• things, so the next person does not have to rediscover what you worked
• out.

What we are looking for

• Around two to three
• years of commercial software development experience, or a comparable
• track record through an apprenticeship, a placement year, a bootcamp
• followed by real delivery, or substantial open-source work.
• A solid grounding in at
• least one modern language, ideally C# or TypeScript. Others count: if
• you have written good Java,
• Go or Python, the move across is very
• manageable.
• A working understanding of
• how a web application fits together: HTTP, REST APIs, JSON, and a
• database of some kind.
• Comfort with Git and a
• pull-request workflow.
• Some experience of writing
• automated tests, and a clear sense of why they matter.
• Clear written
• communication and the confidence to say when you are stuck. On a
• remote team this counts for more than it would in an office.
• A genuine appetite for
• cloud engineering. You do not need Azure experience; you do need to
• want it.
• The technology you will work with

This

• is the stack the platform actually runs on, so you can see what you would be
• working with and learning. It is not a checklist you need to tick. We
• expect someone at this level to have used only a small part of it. Experience
• with any of it is welcome, none of it is essential, and we will teach you the
• rest.
• Backend and API development

The engineer-facing single-page application

Vite

• The build and local development tooling for that application
• Nice to have
• None of these are
• required. Any of them would give us something to talk about.
• Exposure to a cloud platform, Azure, AWS or Google Cloud. A
• personal project counts.
• Experience with React, or another modern component
• framework.
• Curiosity about data and query languages: SQL, KQL or
• similar.
• Docker or containers, even at a hobby level.
• An interest in industrial engineering, energy or
• sustainability.
• A degree in computing, engineering, physics or mathematics,
• though we do not require one.

About you

• Curious. You want to know why the code does what it
• does, not only that it works.
• Honest about what you do not know. Asking early is a
• strength on this team, not a weakness.
• Careful. You test your own work before you ask someone
• else to look at it.
• Coachable. You take code review as a gift, act on the
• feedback, and carry it forward.
• Communicative. Remote work rewards people who write
• clearly and post progress without being chased for it.
• Interested in the real world behind the data: the steam
• trap, the pump, the process that the numbers came from.
• Support and development

We are

• hiring at this level deliberately, and we plan to invest accordingly.
• A named mentor from your first day, plus
• regular one-to-ones with your line manager.
• Pairing and code review with senior
• engineers as a normal part of the week, not a favour you have to ask for.
• Onboarding material written for newcomers,
• including an internal guide to how the platform fits together.
• Time and budget for learning: Microsoft
• certifications, courses and conferences.
• A written progression path towards
• Developer and Senior Developer, with the expectations for each level set
• out rather than implied.
• Work chosen to stretch you on purpose,
• starting well-scoped and growing as you settle in.

How we work

• Remote-first, UK-based. The team works remotely across
• the UK, with occasional travel to Cheltenham or another Group site for
• planning, team events and customer workshops.
• Agile delivery in short iterations, with product
• owners and solution architects embedded in the team.

Quality gates in the pipeline, not in a handover

• automated tests, static analysis and build-enforced standards.
• Infrastructure as code by default. Environments are
• described in Terraform and Bicep and deployed through Azure DevOps.
• Documentation as part of the work, not a phase at the
• end of it.
• No blame when something breaks. We fix the system that
• allowed it, not the person who triggered it.

Why join us

You would work on a

• platform with a direct line to decarbonisation: the telemetry and calculations
• we build help industrial customers find steam leaks, cut fuel use and reduce
• emissions across thousands of sites. For someone early in their career it is an
• unusually good combination, a modern Azure estate with real scale and real
• customers, inside a stable FTSE 100 engineering group, on a team small enough
• that your work is visible and your questions get answered.
• Diversity, equity and inclusion

• qualified candidates regardless of age, disability, gender identity, marital or
• civil-partnership status, pregnancy or parental status, race, religion or
