WCS Software Architect
Overview
We are seeking a hands-on Software Architect to play a key role in shaping and evolving a mission-critical Warehouse Control System (WCS) used in highly automated logistics environments. This platform sits at the heart of real-time operations, orchestrating material flow across conveyor systems, integrating with PLC controls, robotics (AMR/AGV), and upstream enterprise platforms such as WMS and ERP.
Key Responsibilities
Architecture & Technical Leadership
- Define and evolve the architecture across application, data, messaging, and deployment layers
- Lead the design of complex features and subsystems, producing clear design artefacts and architecture documentation (including ADRs)
- Make key technical decisions across persistence, messaging, caching, and integration patterns
- Ensure solutions meet non-functional requirements including performance, scalability, availability, and security
- Troubleshoot and resolve complex system issues, including concurrency, bottlenecks, and integration failures
Systems Integration
- Own and define integration patterns between the WCS platform and external systems including PLCs, WMS, ERP, and robotics platforms
- Design robust, scalable messaging and API-based interfaces
- Ensure resilience through clear contract definitions, error handling, and recovery strategies
- Support emulation and pre-deployment validation approaches to reduce risk
Client-Facing & Delivery Support
- Act as a technical authority in client workshops, design reviews, FAT/SAT, and commissioning phases
- Provide support during go-live activities, including system tuning, troubleshooting, and stabilisation
- Collaborate with delivery and project teams to ensure integration success
- Maintain a calm, solution-focused approach in high-pressure live environments
Technology Strategy & Governance
- Contribute to architectural standards, coding guidelines, and design governance
- Evaluate new tools and technologies, making evidence-based recommendations
- Ensure alignment between business requirements, architecture decisions, and delivered solutions
- Drive best practices across performance, observability, and system resilience
Collaboration & Mentoring
- Work closely with product, development, test, and controls engineering teams
- Provide visibility of architectural direction, risks, and readiness to stakeholders
- Mentor and support engineers, raising overall technical capability within the team
- Promote a culture of high-quality engineering and continuous improvement
Skills & Experience Required
- Proven experience as a Software Architect or a senior/lead engineer stepping into architecture
- Strong expertise in C# / .NET and modern application development practices
- Experience designing distributed systems, microservices, and high-performance applications
- Solid background in system integration (APIs, messaging, event-driven architecture)
- Exposure to industrial systems, warehouse automation, WCS/WMS, or similar environments
- Experience working with PLCs, robotics, or real-time control systems (desirable)
- Knowledge of CI/CD, containerisation (Docker/Kubernetes), and Linux-based environments
- Strong problem-solving ability, with experience in performance tuning and scalability challenges
- Excellent communication skills with the ability to engage both technical and non-technical stakeholders
Working Environment
Fully remote role with flexibility in working patterns
Involvement in occasional onsite activities during key project phases such as system go-lives and commissioning
Collaborative, engineering-led environment focused on delivering high-quality, real-world solutions
Opportunity to work on a platform undergoing significant modernisation and growth
What We're Looking For
- A hands-on technical leader who takes ownership of architectural outcomes
- Someone pragmatic, detail-oriented, and confident in making decisions
- A strong collaborator who can work across disciplines and teams
- An individual who can balance long-term architectural vision with delivery priorities
- A professional who thrives in complex, real-time, integration-heavy environments
