Senior / Expert Backend Software Engineer

Cho Tot team is expanding to continuously innovate our marketplace ecosystem to better serve Vietnamese via advance technology. We are looking for talented and passionate individuals to join our foundation software engineering team.

You will be one of the few key talents who build and run services that are used by ten of millions of Vietnamese people. You will need to tackle highly scaled distributed systems, work in highly automated DevOps environment on top of many open source, CNCF softwares. You will be supported by our solid SRE team to really craft the software and run the product that you are proud of and other engineers admire.

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.

Benefits:

• Get 15 days of annual leave and 5 days of sick leave per year.
• Health insurance for employee.
• Get a 13th-month salary and annual performance bonus.
• Participate in regular team-building activities and company parties.
• Full of learning and training opportunities to grow your professional and personal skills.
