Job Requirements

  • 5+ years of professional software engineering experience, including senior/lead-level architecture responsibility
  • Hands-on experience with actor-model distributed systems (Microsoft Orleans strongly preferred; Akka or comparable frameworks considered)
  • Strong backend expertise in C#/.NET — API design, services, data pipelines at scale
  • Experience architecting systems that process realtime/streaming data (telemetry, sensor data, WebSockets)
  • Proven track record leading a small engineering team — code review, mentoring, setting technical direction
  • Experience working closely with a Project Manager on planning and delivery, including joining client calls to speak to technical topics
  • Strong written and spoken English — comfortable communicating with both engineers and non-technical stakeholders
  • Security-conscious architecture practices (authentication, PII handling, system hardening)

Benefits

  • Remote work (Vietnam-based)
  • Estimated project duration: 19 weeks
