Senior & Principal Java Camunda Enigneers

We're looking for an experienced Java Camunda Engineer to join our implementation team. You'll work across Camunda BPMN/DMN process automation, API integration, and microservice orchestration, helping our 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.

At Principal level, you'll additionally own solution architecture and technical strategy across engagements, act as the senior technical voice with our clients, lead delivery teams, and contribute to bids, pre-sales activity, and the growth of our engineering practice.

This is an ideal role for someone who enjoys solving complex process problems through clean code, automation, and modern engineering practices.

Key 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

• Support migration of legacy process platforms to Camunda 8 / Zeebe where applicable

• Contribute to Casci's internal best-practice frameworks and automation accelerators

• Strong experience in Java software engineering and object-oriented design

• Hands-on experience implementing solutions using Camunda 7 or 8 (BPMN/DMN)

• Proven experience leading and mentoring teams of engineers to deliver high-quality, production-grade software (expected at Principal level)

• Familiarity with Spring Boot, REST APIs, and microservice architectures

• Knowledge of Docker, Kubernetes, Git, CI/CD pipelines, and automated testing frameworks

• Good knowledge of security, authentication, and integration patterns for enterprise systems

• Excellent problem-solving, communication, and collaboration skills, with experience working in agile teams on digital transformation or automation programmes

• Must be eligible for UK SC Security Clearance and prepared to undergo it - this typically requires having lived in the UK continuously for the past 5 years

Desirable Skills and Experience

• Experience with Camunda 8 (Zeebe) clusters and Operate/Tasklist components

• 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 event-driven design and message brokers (e.g. Kafka, RabbitMQ)

• Understanding of agentic AI capabilities and how they can complement workflow automation

• Experience contributing to open-source Camunda extensions

• Holds UK security clearance
