About the Role

As a Senior Software Engineer, you will play a key role in designing, building, and evolving highly scalable, cloud‑native software solutions that support business‑critical financial applications. You’ll work closely with architects, product partners, and other engineers to deliver high‑quality systems while contributing technical leadership and helping shape long‑term architectural direction.

This role is ideal for a hands‑on senior engineer who enjoys solving complex technical problems, mentoring others, and working across the full software development lifecycle.

  • Contribute to the design and implementation of scalable, secure, and maintainable software solutions using modern architectural best practices.
  • Participate in architecture and design discussions, ensuring solutions support long‑term scalability, performance, and reliability.
  • Translate business requirements into technical designs and clear implementation plans.

Development & Delivery

  • Design and develop backend services and APIs using Java, Spring Boot, and RESTful architectures.
  • Build and maintain cloud‑native microservices following Twelve‑Factor Application principles.
  • Develop high‑throughput, low‑latency applications using appropriate strategies such as caching, load balancing, and concurrency.

Cloud, DevOps & Reliability

  • Build, deploy, and support applications in cloud environments, with a strong focus on Kubernetes‑based platforms and AWS services.
  • Support CI/CD pipelines and modern DevOps practices using tools such as GitHub, Jenkins, Maven, Nexus, and SonarQube.
  • Act as a technical escalation point for production issues, supporting root‑cause analysis and long‑term remediation.

Quality, Security & Collaboration

  • Write clean, well‑tested code using unit testing, mocking frameworks, and test‑driven development practices.
  • Ensure applications follow security best practices and address common web application vulnerabilities.
  • Establish and document development standards, testing strategies, and operational procedures.
  • Mentor junior engineers and contribute to a collaborative, Agile development environment.

What You Bring

Core Experience

  • 7+ years of professional software engineering experience (or equivalent practical experience).
  • Strong proficiency in Java and enterprise frameworks such as Spring (IoC, MVC, Transactions, Security, Batch), Spring Boot, JPA/Hibernate, and RESTful services.
  • Solid understanding of object‑oriented and service‑oriented design patterns.

Cloud & Platform Expertise

  • Experience building and running applications in cloud environments, ideally AWS (e.g., EKS, EC2, S3, Lambda, API Gateway, SQS, DynamoDB).
  • Hands‑on experience with containerization and orchestration technologies such as Docker and Kubernetes.
  • Familiarity with event‑driven architectures and messaging technologies (e.g., Kafka, MQ).

Front‑End & DevOps

  • Experience with front‑end technologies such as JavaScript, TypeScript, HTML5, CSS3, and modern frameworks (e.g., Angular).
  • Experience with CI/CD pipelines and Agile development tools such as Git/GitHub, Jenkins, Jira, Maven, and SonarQube.

Ways of Working

  • Experience working in Agile/Scrum environments.
  • Strong communication skills and the ability to collaborate across technical and non‑technical teams.
  • A continuous‑learning mindset and a passion for building high‑quality software.
