The ideal candidate is an experienced backend engineer who thrives on working with data, has strong architectural and design skills, and is passionate about building reliable platforms that empower thousands of datasets and users across the company. Beyond technology, we value a customer-focused mindset, ensuring that the systems we build provide maximum value to end-users.


Key Responsibilities

  • Contribute across the full software development lifecycle, from requirements gathering and architecture to deployment and support.

  • Collaborate with end-users and internal teams to refine requirements, share best practices, and provide hands-on support.

  • Build robust monitoring, alerting, and observability solutions for the platform.

  • Participate in code reviews, technical discussions, and on-call rotations in a global, collaborative engineering team.

  • Deliver high-quality software that is well-tested, documented, and production-ready.


Minimum Qualifications

  • 7+ years of professional software development experience.

  • Strong expertise in Python or Golang and building distributed systems.

  • Experience with APIs (REST/RPC), real-time streaming (Kafka, Flink, etc.), and analytical databases.

  • Proficiency with both SQL and NoSQL databases (time-series DBs a plus).

  • Familiarity with CI/CD, infrastructure as code, and containerization (Docker; Kubernetes a plus).

  • Cloud experience (AWS preferred).

  • Self-starter with strong problem-solving skills and eagerness to learn complex systems.


Preferred Qualifications

  • Experience with Jenkins, GitHub Actions, or other automation tools.

  • Background in highly available distributed systems.
