About This Opportunity

We are building an automation team dedicated to transform the way we perform testing. This team focuses on developing automation frameworks and tools for everything that is repeated twice or more. The automation team will focus on automating system tests, acceptance tests, and integration tests. We are looking for a person who is passionate about automation and technology, possesses a collaborative mindset, and has a deep curiosity as to how things work ‘under the hood.’ We want those that are both self-directed and able to serve as leaders and mentors for this growing team.

You should be a passionate, results-oriented, experienced software developer. If you thrive in a fast-paced environment, have a relentless focus on the customer experience and want to build something new rather than just maintain someone else’s code, then this role is for you.

This position is based in Sri Lanka.

• Build & ship: Contribute to the design, development, and deployment of scalable applications using Kubernetes, Go, Python, Protobuf, gRPC, and REST API .
• Think in microservices: Help design and maintain scalable microservices architecture.
• Work with real-world big data: Optimize and process large datasets efficiently.
• Get hands-on with streaming data: Work with Kafka and real-time data processing (we’ll teach you if you’re new to it!).
• Deploy like a pro: Use Helm to deploy and manage Kubernetes applications.
• Work like a pro: Debug, test, and refine software to ensure high code quality and reliability.
• Learn & grow: Work closely with a seasoned Senior Engineer who will mentor and support you.

What We Are Looking For

• Bachelor’s degree in Computer Science or a related field (or equivalent work experience).
• 7+ years of software development experience (or solid projects if you’re a fast learner!).
• Experiencing in leading small teams across multiple streams.
• Proficiency in Java, Go, Python, Kubernetes, Protobuf, gRPC, REST API , and micro-services architecture.
• Passion for data-heavy applications and handling large datasets.
• Familiarity with microservices architecture and distributed systems.
• Bonus points if you’ve worked with Kafka or Helm (but if not, we’ll help you learn!).
• Knowledge of JVM-based languages is advantageous but optional.
• A growth mindset – we don’t expect you to know everything, but we expect you to be excited to learn.
