Software Developer – APIs and Process Automation

Location:HL Tower, 82 Duy Tan, Ha Noi (Onsite)

We are looking for 2 Python Backend Developers with a strong data foundation (SQL, data pipelines, workflow orchestration) to join SETA's engineering team.

You will build data-driven backend services and automated workflows that turn manual operational requests into reliable, self-running pipelines – from validation and execution to verification – on Google Cloud. This is a hands-on role for engineers who write clean Python, think in data, and care about reliability.

Responsibilities

• Build and maintain Python backend services and REST APIs that support operational workflows.
• Design and develop data pipelines and scheduled workflows with Airflow / Cloud Composer and Pub/Sub, covering validation, execution, verification and status updates.
• Write efficient SQL, design data models and work with BigQuery and relational databases.
• Ensure reliability with idempotency, retries, error handling, monitoring and audit trails.
• Integrate internal platforms, databases and third-party systems.
• Deploy and run services on GCP (Cloud Run, GKE, Cloud Functions, BigQuery, Pub/Sub).
• Write automated tests, join code reviews and support CI/CD and production releases.
• Work with operations and product teams to turn manual processes into self-service workflows.
• Further details will be discussed during the interview.

Your Skills & Experience

• Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related field.
• 3+ years of software development experience (Middle level or above) with Python as the main language.
• Strong SQL: complex joins, aggregations, window functions, query optimization, indexing and data modeling.
• Solid Python fundamentals and OOP; comfortable with live coding.
• Experience building data pipelines or automated workflows: scheduling (cron), retries, idempotency and state management.
• Experience building and consuming REST APIs and integrating databases and third-party systems.
• Hands-on cloud experience, preferably GCP (AWS or Azure is also acceptable); familiarity with Docker, Git and CI/CD.
• Working knowledge of AI/LLM tools to speed up development is a plus.
• Confident English communication to work directly with international stakeholders.

Nice to Have

• Hands-on experience with Airflow / Cloud Composer or similar orchestrators (Argo Workflows, AWS Step Functions, Temporal, Prefect).
• Experience with BigQuery or other data warehouses, and streaming tools such as Pub/Sub or Kafka.
• Experience with data quality, reconciliation or CDC pipelines.
• Background in Network, Telecom, IoT or BSS/OSS domains, or working with international clients.

What Success Looks Like

• Manual operational requests run as scheduled, traceable workflows that are idempotent, retry safely and recover from failures.
• Data is modeled and queried efficiently, and pipeline results are accurate, verifiable and visible to operations teams.
• Services and pipelines are tested, maintainable and supported by solid monitoring and release practices.

Benefits

• Salary: Upto 50M Gross
• Attractive salary, performance-based bonus and annual salary review.
• Full benefits according to Vietnam Labor Law (Social & Health Insurance).
• Work with an international engineering team on large-scale automation and cloud projects.
• Hands-on exposure to GCP data services (BigQuery, Pub/Sub, Cloud Composer), workflow orchestration and practical AI/LLM use cases.
• International, professional, young and innovative working environment.
• Opportunity to join technology conferences/workshops and knowledge-sharing sessions.
• Holidays and paid leave according to Vietnam Labor Law.
• Company trip & team building activities.
