A growing clean-energy engineering business is looking for a hands-on Senior PLC Software Engineer to support the development of next-generation ammonia cracking systems. This role will focus on developing and implementing PLC-based control systems as the business continues to transition from prototype into scalable, deployable products. You’ll be working across the full lifecycle from software design through to real-world commissioning playing a key role in ensuring systems operate reliably in live environments. This is a technical expert role, suited to someone who enjoys owning problems, improving development processes, and working closely with physical systems.
What you’ll be doing:
- Designing and developing PLC software for ammonia cracking systems.
- Programming PLCs (Siemens S7 / TIA Portal preferred, others considered).
- Working within an existing system architecture, with increasing input over time.
- Defining and improving software development processes and standards.
- Producing structured, maintainable code (IEC 61131-3).
- Supporting software verification and validation (including simulation where applicable).
- Integrating PLC systems with wider control architecture (HMI, SCADA, instrumentation).
- Supporting and leading commissioning activities, fault finding and debugging on live systems.
- Working closely with multidisciplinary teams across mechanical, electrical and systems engineering.
- Supporting data acquisition and system connectivity where required.
What we’re looking for:
- Proven experience in industrial automation within Chemical processing or Manufacturing environments.
- Strong PLC programming experience (Siemens S7 ideal, others considered).
- Experience across the full lifecycle: design, development, testing and commissioning.
- Strong fault finding and on-site debugging capability.
- Experience working on complex engineered or process systems.
- Ability to bring structure and rigour to software development processes.
- Desirable:
- Experience with simulation or software verification environments.
- Exposure to process systems, energy systems or similar technologies.
- Understanding of industrial communication protocols.
Why apply:
- Work on cutting-edge hydrogen and ammonia energy technology.
- Be part of scaling a novel technology from prototype to commercial deployment.
- High-impact, hands-on engineering role.
- Flexible hybrid working with real autonomy.
- Opportunity to shape how control systems are developed as the business grows.
