This role demands strong expertise in distributed systems, deep hands-on development skills, and the ability to simplify complex solutions while maintaining performance, scalability, and security.

  • Collaborate with SDEs across teams to align on technical solutions and integration.
  • Lead by example through high-quality design, code, and processes, setting benchmarks for the team.
  • Influence technical and business strategy by proposing novel approaches and simplifications.
  • Communicate complex technical ideas clearly with stakeholders, drive feedback loops, and achieve convergence on solutions.
  • Mentor and coach engineers, support hiring efforts, and grow the technical strength of the team.
  • Identify and address design or architectural deficiencies; simplify peer team integrations.
  • Consistently deliver valuable features end-to-end, from requirements to production.
  • Drive process improvements in development, testing, and delivery.
  • Collaborate with Product Owners to elaborate requirements and deliver business value.

Required Skills

Programming & Development

  • Deep expertise in Java, IDEs, frameworks, and toolsets.
  • Strong in data structures, algorithms, multithreading, and concurrent programming.
  • Skilled in TDD/BDD, comfortable writing testable and maintainable code.
  • Ability to profile, debug, and optimize complex systems.
  • Good knowledge of multiple languages and paradigms, and when to apply them.

System Design & Architecture

  • Apply design patterns (CQRS, eventual consistency, etc.) effectively.
  • Strong understanding of SOLID principles and domain modeling.
  • Design with idempotency, scalability, and performance in mind.
  • Anticipate medium-term (3–6 month) changes and design abstractions accordingly.
  • Deep knowledge of distributed systems, scaling, replication, and sharding.
  • Expertise in Microservices Architecture and API design.

Development Practices

  • Automate build, test, and deployment pipelines (CI/CD).
  • Integrate security scanning, performance testing, and monitoring into workflows.
  • Champion "automate everything by default" culture.

Infrastructure & Cloud

  • Expertise in at least one database, with knowledge of multiple data storage paradigms (SQL, NoSQL, caching, messaging).
  • Good grasp of operating systems and scripting techniques.
  • Strong experience with cloud platforms (Azure preferred; AWS/GCP a plus).
  • Familiar with DevSecOps practices and tools.

Security

  • Write secure code by default, proactively addressing vulnerabilities.
  • Use tools to perform deep security probes and reviews.

Collaboration & Leadership

  • Lead group design discussions and present ideas effectively.
  • Mentor and develop peers, contributing to overall team growth.
  • Deep domain understanding to work effectively with Product Owners.
  • Share knowledge with the wider engineering community.

Innovation
