In this role, you will be a key hands-on contributor, driving technical excellence by implementing best practices in Golang development for deterministic and resilient platform solutions.

3. Responsibilities

System Design & Implementation

• Design and implement scalable, resilient backend platforms and ingestion services leveraging Golang.
• Architect solutions that ensure deterministic workflow execution and durable data processing across distributed components.
• Contribute to technical standards and methods that support reliability, idempotency, and observability in a modern engineering stack.
• Conduct technical evaluations of storage, messaging, and orchestration technologies to inform design decisions.

Hands-On Development

• Deliver high-performance Go services and internal APIs that handle complex data ingestion and transformation.
• Write clean, maintainable, and idiomatic Go code, setting a high bar for quality within the team.
• Mentor other engineers through thoughtful code reviews, pair programming, and sharing expertise on complex technical topics.
• Continuously evaluate and evolve architectural choices to meet changing compliance and throughput requirements.

4. Qualifications

Must-Have Technical Expertise

• 7+ years as a software engineer, including 3+ years building backend platforms, APIs, or distributed systems in Golang.

• Strong decision-maker with a pragmatic approach to engineering tradeoffs (e.g., consistency vs. availability).
• Excellent communicator; able to articulate complex distributed system concepts to stakeholders.

Preferred

• Experience with durable execution frameworks (e.g., Temporal concepts) or event streaming (e.g., NATS/Kafka).
• Prior experience with schema evolution and canonical data modeling.
• Strong Vietnamese and English Communication Skills.

5. Working Model & Contract

• Remote 100%.
• Working time: Vietnam Time
• Long-term contract (duration 6 - 12months)

Also, just to be aligned, please note that generally it will be 4 Interviews:

• Initial Screening (15mins): General Suitability, Technical Questions
• Non-Technical Interview (30mins): Team & Culture Fit, Compensation
• Technical Interview (1hour): Very technical, expect to live code and/or receive coding assignments
• Final Interview (30min-1hour): With all stakeholders, answer any open questions on both sides, which can be technical.
