  • Integrity: You believe in doing the right thing, even when it's uncomfortable, seemingly inefficient, or costly.
  • Purposefulness: You have a desire to serve others with your skillset and an openness to continuous learning and growth.
  • Ownership: You stick to your commitments, follow up with action, and seek clarity in communication & expectations.

YOUR EXPERIENCE:

• 5+ years building scalable, distributed backend systems using microservices.
• Experience designing and deploying production-grade APIs in cloud-native environments (ideally in GCP).
• Hands-on experience with event-driven architectures using Kafka or Google Pub/Sub.
• Strong familiarity with distributed caching techniques (e.g., Redis, Memcached).
• Ability to lead technical conversations, provide architectural guidance, and support mentoring of junior engineers.
• Solid experience with version control systems (e.g., Git) and modern CI/CD pipelines.
• Strong problem-solving skills and comfort working in a fast-paced, iterative development environment.

WE'D BE THRILLED IF YOU HAVE:

• Experience in large-scale eCommerce or retail systems.
• Exposure to catalog or product information management platforms.
• Prior consulting experience or background supporting high-visibility projects under tight timelines.
