What You Will Do
- Design and build large-scale distributed backend systems and graph-based data models.
- Develop high-throughput, low-latency data ingestion and processing pipelines using Python and Go.
- Own significant features end-to-end, from technical design to production rollout.
- Partner with product and security research teams to deliver new capabilities at scale.
- Identify production risks and build observable, resilient solutions before they become customer-impacting issues.
- Collaborate with engineers through design reviews, code reviews, and technical discussions.
What We Are Looking For
- 7+ years of software engineering experience, with significant experience in backend systems.
- Strong proficiency in Python and/or Go.
- Hands-on experience designing, building, and operating distributed systems in production, including replication, partitioning, backpressure, and idempotency.
- Experience with graph data and graph databases such as Neo4j, JanusGraph, Neptune, TigerGraph, or similar tools.
- Strong understanding of storage and streaming systems, including PostgreSQL, NoSQL databases, S3, Kafka, and Redis.
- Experience designing APIs and backend services for high-traffic, multi-tenant workloads.
- Familiarity with Docker, Kubernetes, and cloud platforms such as AWS or GCP.
- Strong communication skills, including the ability to contribute to design discussions and write clear technical documents.
- Solid understanding and application of secure coding practices, including secrets management, access control, and handling of sensitive data throughout the software development lifecycle.
- Strong awareness of protecting source code, technical documentation, and customer data, while complying with company information security policies in a remote working environment.
- Ability to collaborate with QA/IT/ISRM teams to remediate vulnerabilities, address information security risks, and support incident investigation when required.
- Strong proficiency in English communication.
Nice to Have
- Experience building cybersecurity products.
- Background in graph-based analytics, knowledge graphs, or relationship-driven risk modeling.
- Exposure to query engines, query optimization, or traversal and query layers.
- Experience with observability or real-time stream processing tools such as Grafana, Prometheus, OpenTelemetry, Flink, or Spark Streaming.
- Contributions to open-source distributed systems or graph-related projects.
AI-Native Engineering Expectations
- As part of an AI-forward engineering environment, senior engineers are expected to use AI tools thoughtfully and contribute to AI-ready systems.
- You should be comfortable with:
- Using AI-powered developer tools and critically evaluating AI-generated outputs.
- Core AI/ML concepts such as LLMs, embeddings, vector databases, retrieval, inference, and evaluation.
- Building AI-ready data infrastructure such as knowledge graphs, RAG pipelines, feature stores, or vector indexes.
- Supporting reliability, observability, and performance in AI-driven systems.
Why You’ll Enjoy Working With This Team
- Join the founding engineering team of a growing Vietnam R&D hub with strong long-term investment.
- Work on large-scale distributed systems, graph data platforms, and AI-driven security products used by enterprise customers globally.
- Own meaningful product features from design to production and contribute to engineering standards from an early stage.
- Collaborate closely with experienced global engineering and security research teams.
- Solve technically challenging problems with meaningful product impact.
Working Model
This role is based in Ho Chi Minh City and is expected to be primarily in-office during the founding stage (at least 3 days per week). Working closely together will help the early team collaborate effectively, build technical trust, and establish a strong engineering culture as the R&D hub grows.
