  • Define and drive technical architecture, coding standards, and development best practices.
  • Provide technical guidance and mentorship to development teams.
  • Conduct code reviews and ensure high-quality, maintainable, and secure code.
  • Collaborate with Solution Architects and Engineering Managers on technology roadmaps and architectural decisions.

Application Development

  • Design and implement RESTful APIs and microservices-based solutions.
  • Develop scalable, resilient, and high-performing Back End services.
  • Integrate with internal and external systems through APIs, messaging platforms, and event-driven architectures.
  • Ensure compliance with security, performance, and reliability requirements.

Architecture & Design

  • Participate in system architecture, technical design discussions, and solution planning.
  • Drive cloud-native development practices and modernization initiatives.
  • Identify and mitigate technical risks and performance bottlenecks.
  • Ensure scalability, maintainability, and extensibility of software solutions.

DevOps & Delivery

  • Support and enhance CI/CD pipelines and automated deployment processes.
  • Collaborate with DevOps teams to implement containerized and cloud-based solutions.
  • Contribute to Infrastructure as Code (IaC) initiatives using tools such as Terraform.
  • Participate in release planning, production deployments, and incident management.

Stakeholder Collaboration

  • Work closely with Product Owners, Business Analysts, Architects, QA, and DevOps teams.
  • Translate business requirements into technical solutions.
  • Communicate technical concepts effectively to both technical and non-technical stakeholders.

Required Skills & Qualifications
Technical Skills

  • 8+ years of hands-on software development experience with Java.
  • Strong expertise in Java and Spring Boot frameworks.
  • Extensive experience designing and implementing microservices architectures.
  • Strong knowledge of RESTful API design and integration.
  • Experience with Hibernate, JPA, and ORM frameworks.
  • Hands-on experience with messaging technologies such as Kafka or RabbitMQ.
  • Experience with cloud platforms including AWS, Azure, or GCP.
  • Strong experience with Docker and Kubernetes.
  • Proficiency with relational and NoSQL databases such as PostgreSQL, MySQL, MongoDB, or similar.
  • Deep understanding of application security, authentication, authorization, and secure coding practices.
  • Experience with performance tuning, monitoring, and troubleshooting distributed systems.
  • Strong knowledge of Git, branching strategies, and Agile/Scrum methodologies.

Leadership Experience

  • Proven experience leading development teams and delivering complex enterprise projects.
  • Ability to mentor developers and foster technical excellence.
  • Experience managing technical deliverables, estimations, and development planning.

Preferred Qualifications

  • Experience working within regulated, standards-driven, or public sector environments (eg, GDS-aligned projects).
  • Experience implementing cloud-native architectures and event-driven systems.
  • Familiarity with Infrastructure as Code tools such as Terraform or CloudFormation.
  • Experience with observability and monitoring tools such as ELK, Grafana, Prometheus, or Splunk.
  • Relevant Java, AWS, Azure, GCP, Kubernetes, or architecture certifications.
  • Experience with Domain-Driven Design (DDD) and API-first development approaches.

Soft Skills

  • Strong leadership and decision-making capabilities.
  • Excellent analytical and problem-solving skills.
  • Effective communication and stakeholder management abilities.
  • Strong collaboration and team-building mindset.
  • Ability to balance technical excellence with business objectives.
  • Self-motivated with the ability to work independently and lead distributed teams.

Nice to Have

  • Exposure to government, healthcare, banking, or other highly regulated industries.
