• Define and enforce engineering standards for coding, testing, debugging, and deployment, driving consistency and quality across the development team.
• Collaborate with architecture and infrastructure teams to ensure application designs align with the broader technology blueprint and long-term platform strategy.
• Provide Tier 3 production support, diagnosing and resolving high-impact incidents through structured analysis and advanced troubleshooting techniques.
• Mentor and guide mid-level developers and analysts, allocating work effectively and building technical capability across the team.
• Partner with engineering and product stakeholders to identify system enhancement opportunities and translate business requirements into practical, high-quality technical solutions.

Required Qualifications & Skills

• 6+ years of hands-on experience developing and maintaining enterprise shared services using Java, Spring Boot, and MongoDB.
• Deep expertise in Java 8, Apache Camel, JMS, WebSphere MQ, TIBCO EMS, OSGi, REST APIs, SSL, and related open-source technologies.
• Demonstrated ability to perform critical-situation troubleshooting across complex, high-traffic backend environments.
• Practical knowledge of DevOps tooling, including GitHub, uDeploy, and SonarQube, with experience integrating these into an Agile development lifecycle.
• Working knowledge of SQL and the ability to apply it effectively in application analysis, tuning, and performance measurement.
• Proven ability to lead technical delivery, manage competing priorities, and operate with professional maturity across all levels of an organization.
• Bachelor's degree in a relevant field, or equivalent practical experience.

Beneficial Skills & Qualifications

• Experience with containerization technologies such as Docker and OpenShift.
• Familiarity with critical-incident diagnostic tools including Samurai, Thread Dump Analyser (TDA), or Memory Analyser Tool (MAT).
• Hands-on experience with Linux command-line administration, particularly in Red Hat Enterprise Linux (RHEL) environments.
• Experience with the Lightspeed deployment platform within a regulated or enterprise financial services context.
• Master's degree in Computer Science, Engineering, or a related discipline.
