Overview
This company is a Workflow & AI Orchestration Specialist. They're on a mission to modernise how public sector organisations manage casework, derive insight from data and deliver citizen services. They’re growing fast and looking for bright, dynamic people to help build their business.
Role
They’re looking for an experienced (Principle/Team Lead) Java Engineer to join their implementation team.
You’ll work across Camunda BPMN/DMN process automation, API integration, and microservice orchestration — helping their public-sector clients build secure, scalable, and resilient digital services.
You’ll collaborate with solution architects, business analysts, and designers to translate workflows into elegant, maintainable code. You’ll play a key part in defining technical standards, optimising runtime performance, and mentoring less- experienced engineers in workflow-centric delivery.
This is an ideal role for someone who enjoys solving complex process problems through clean code, automation, and modern engineering practices.
The role involves visiting client sites; the company will cover travel expenses. Frequency is uncertain but candidates should be comfortable with that being 2-3 days per week. Client sites could be anywhere but will most likely be in & around London.
Responsibilities
Design, develop, and deploy Camunda-based process and decision automation solutions
Implement and integrate Java-based microservices, APIs, and connectors within orchestration flows
Translate BPMN and DMN models into executable workflows and reusable components
Collaborate closely with analysts and service designers to refine and iterate business processes
Develop and maintain automated test suites, CI/CD pipelines, and containerised deployments
Optimise Camunda engine performance and monitor workflow metrics for production environments
Participate in code reviews, peer testing, and technical design discussions
Contribute to their internal best-practice frameworks and automation accelerators
Essential
Eligible (have resided in the UK for the past 5 years) and prepared to go through UK SC Security Clearance
Strong experience in Java software engineering and object-oriented design

Knowledge of Docker and Kubernetes for containerisation and orchestration
Proficiency in Git, CI/CD pipelines, and automated testing frameworks
Understanding of event-driven design and message brokers (e.g. Kafka, RabbitMQ)
Good knowledge of security, authentication, and integration patterns for enterprise systems
Experience working in agile teams within digital transformation or automation programmes
A willingness to learn BPMN and Camunda tooling
Some exposure to process automation or microservice orchestration
Desirable
Experience with Camunda 8 (Zeebe) clusters and Operate/Tasklist components
Experience implementing solutions using Camunda 7 or 8 (BPMN/DMN)
Familiarity with Camunda connectors, external task workers, and scripting extensions
Exposure to cloud platforms (AWS, Azure, GCP) and infrastructure-as-code (Terraform, Helm)
Experience integrating process automation with case-management or service-orchestration platforms
Understanding of agentic AI capabilities and how they can complement workflow automation
Experience mentoring developers or contributing to open-source Camunda extensions
Already holding UK security clearance (SC, DV, eDV)
