Senior OT Systems Engineer

As a Senior OT Systems Engineer with a focus on PLC / SCADA, you help industrial clients deliver process automation improvements using factory automation tooling. You combine deep S7/TIA engineering with consultancy\-grade stakeholder management, junior coaching, and disciplined delivery from design to commissioning. This role builds a pathway toward a future Team Leader position.

Tech stack focus

• PLC: Siemens S7 / TIA Portal


• SCADA: iFIX, Ignition, WinCC

Where you add value

• You assess the as\-is PLC, SCADA, and industrial network landscape (architecture, standards, performance, and risk hotspots) and translate findings into a prioritized improvement roadmap.


• You deliver continuous process automation using factory automation tooling. You engineer stable process behaviour: sequences, phases, interlocks, abnormal situation handling, and predictable recovery.


• You bridge operations, process, and automation: you translate process intent into a control strategy and operator guidance, with explicit trade\-offs on safety, availability, and product quality.


• You reduce start\-up risk through engineering discipline: strong upfront analysis, structured design, test evidence, and clean handover \- fewer commissioning surprises and better repeatability.

• Lead projects as technical lead: define technical approach, standards, align with architects, and execution plan through commissioning and hypercare.


• Drive consultancy\-style delivery: facilitate workshops, challenge assumptions, align stakeholders, and lock decisions.


• Translate process intent into control strategy: operating modes, sequences/phases, interlocks, alarming philosophy, and recovery paths.


• Engineer robust PLC software in Siemens S7 / TIA Portal: modular architecture, diagnostics, safe\-state behaviour, boundary conditions, and maintainability.


• Deliver SCADA solutions in iFIX / Ignition / WinCC: operator\-focused HMI, alarm rationalization, trends, data model and structure from the source, data integrity checks, and usability improvements.


• Own integration topics: industrial connectivity (e.g., OPC), interface definition, network awareness, and structured troubleshooting across layers.


• Execute and steer testing: simulation, FAT/SAT, commissioning, punch listing, and controlled change implementation.


• Coach and direct junior engineers: task breakdown, design/code/test reviews, documentation standards, and professional growth.


• Own engineering time management: flexible planning, dependency management, and early communication of impact on critical milestones (design freeze, FAT readiness, commissioning windows).

Essential skills

• Strong experience in process automation projects using Siemens S7 / TIA Portal and one or more SCADA platforms (iFIX, Ignition, WinCC).


• Scripting/data skills (Python, SQL) for tooling, diagnostics, or data quality work.


• Technical lead maturity: autonomous delivery, decision\-making under constraints, and clear alignment with customers and internal stakeholders.


• Consultancy mindset: you challenge assumptions early, manage expectations, and translate complexity into decision\-ready options.


• People leadership: you steer and grow junior engineers through direction, reviews, and coaching \- without micromanaging.


• Out\-of\-the\-box thinking: you propose pragmatic alternatives when constraints block the default approach, without cutting corners on safety or outcomes.


• Drive and dedication: you take ownership and stay committed until the job is truly done \- issues closed, performance stabilized, and handover complete.


• Continuous improvement: you standardize delivery (libraries, templates, lessons learned) and raise the bar for every project.


• Analytical problem\-solving: you move from symptom \-\> root cause \-\> preventive control, backed by evidence.


• Attention to detail across design, programming, testing, and documentation: boundary conditions, failure modes, test coverage, traceability, and clean handover.


• Quality focus: you understand what drives quality \- clarity up front (requirements and acceptance criteria), disciplined design reviews before coding, standards and peer reviews as real gates, risk\-based testing with evidence, and controlled change management.


• Professional English communication in an international delivery environment.

• Working knowledge of the GAMP V\-model and validation\-style delivery (traceability, test evidence, controlled changes), especially in regulated environments.


• OT/IT exposure: network topologies, cybersecurity basics, and interface\-heavy environments.


• Multi\-platform commissioning and troubleshooting experience across different industrial sites.
