ABOUT THE ROLE & TEAM

We are seeking a highly skilled Lead Software Developer to drive the design, development, and delivery of scalable software solutions. This role requires deep expertise in Java and Python, strong leadership capabilities, and a solid understanding of modern architectures, with exposure to AI-driven systems. Experience with Angular on the frontend is a strong plus.

You will lead a team of engineers, make key technical decisions, and collaborate closely with product, data, and AI teams to build innovative, high-performance applications.

WHAT YOU WILL DO
Lead the design, development and delivery of scalable, secure software solutions using Java and Python, with exposure to AI-enabled components and (ideally) Angular on the frontend.
Architect, build and maintain robust backend services, APIs and microservices (e.g., Spring Boot) and drive clean architecture and engineering best practices.
Ensure solutions are scalable, secure and observable; drive performance tuning, reliability improvements and operational excellence.
Enable integration of AI/ML components and data services where applicable (service interfaces, dependencies, evaluation hooks).
Lead engineering delivery: estimation, planning, code reviews, technical debt management, and CI/CD improvements.
Mentor and guide developers, setting quality standards and enabling team growth through feedback and knowledge sharing.
Collaborate with Product, DevOps and data/AI teams to deliver in an Agile environment.
Qualifications:
WHO YOU ARE
7+ years of software development experience with proven delivery in a senior/lead role.
Strong Java expertise (e.g., Spring Boot, Hibernate) and solid Python experience.
Strong understanding of microservices, REST APIs, distributed systems and system design.
Experience with cloud platforms (AWS, Azure or GCP), containers (Docker) and CI/CD practices.
Solid knowledge of software security fundamentals (IAM, SSL/TLS, OAuth/JWT) and secure coding practices; exposure to compliance frameworks is a plus.
Experience with relational and non-relational databases; understanding of performance tuning and observability.
Nice to have: Angular (or similar), event-driven architectures (Kafka/RabbitMQ), Kubernetes, and familiarity with AI/ML systems and MLOps concepts.
Aviation/OCC domain exposure is a strong advantage
