- Participate in architectural design reviews, focusing on scalability, fault tolerance, and cost optimization.
- Collaborate with cross-functional teams including Product, Program Management, and QA.
- Provide realistic level of effort (LOE) estimates during planning cycles.
- Prototype and experiment with emerging technologies to improve engineering velocity.

Required Skills & Experience

- 5+ years of professional software engineering experience.
- 3+ years of experience building production-grade, highly scalable Go services.
- Expertise in writing high-performance gRPC and REST clients/servers, including protobuf contracts.
- Hands-on experience with Kafka (stream processing, topic management, schema registry, ACLs, consumers, offsets).
- 3+ years of experience with AWS (S3, CloudFront, EKS, etc.).
- 1+ year of experience with GCP (Cloud Storage, Kafka, GKE, CDN, etc.).
- 2+ years of experience designing and using MongoDB.

Nice to Have

- 2+ years developing full-stack applications using Node.Js, MongoDB, Express, and React.
- 3+ years of experience with EKS/GKE, Helm, Terraform, and CI/CD pipelines.
- 1+ year of Linux bash scripting for automation and ops tasks.
- Exposure to Redis, Docker, Git, and observability stacks (Prometheus, Grafana, OpenTelemetry).
- Strong problem-solving, communication, and collaboration skills in a globally distributed team.
- Experience with MongoDB schemas, indexing, and sharding strategies.
- Knowledge of ETL pipelines and CRUD operations.
