Responsibilities:

• Solve complex, ambiguous engineering problems to enable a smart marketplace ecosystem of products and services, often defining the technical direction with minimal guidance.

• Design, build, run, and improve backend services and frameworks for creating microservices, with a strong emphasis on scalability, reliability, and performance at scale.

• Lead technical design reviews, drive architectural decisions, and establish best practices that raise the bar across backend engineering.

• Mentor and uplift fellow engineers through code reviews, pairing sessions, and knowledge sharing.

• Proactively identify systemic issues, tech debt, and operational risks — then drive solutions from proposal through delivery.

• Improve engineering efficiency with common libraries, tooling, and platform capabilities that multiply the output of the broader team.

• Collaborate cross-functionally with product, SRE, and data teams to align technical strategy with business outcomes.

Requirements:

• At least 7 years of professional software engineering experience, with deep hands-on expertise in building and operating large-scale distributed systems in production.

• Strong proficiency in Golang in production environments. Additional mastery of one or more general-purpose languages such as C/C++, Python, Java, or JavaScript/TypeScript.

• Deep understanding of distributed systems concepts: consistency models, partitioning, replication, consensus, fault tolerance, and observability.

• Extensive production experience with three or more data systems such as PostgreSQL, MongoDB, Elasticsearch, Redis, Kafka, or Cassandra — including the ability to evaluate trade-offs and select the right tool for a given problem.

• Strong experience with Docker, Kubernetes, and cloud-native infrastructure patterns.

• Proven track record of designing and evolving microservices and event-driven architectures at scale.

• Demonstrated ability to lead technical initiatives end-to-end: from problem framing and design through implementation, rollout, and production ownership.

• Excellent communication skills — able to articulate complex technical concepts clearly to both engineering and non-engineering stakeholders.

• BA or MA degree in Engineering, Computer Science, or a related technical field. Or formerly competitive programmer.
