Akvelon is looking for Middle and Senior .NET Software Engineers to join a long-term enterprise cloud project.

You will be part of a team responsible for developing and supporting cloud-native services running on Microsoft Azure. The role combines backend development with production support, troubleshooting, and continuous improvement of business-critical services.

We are looking for engineers who are comfortable not only building new functionality, but also investigating production issues and working with distributed cloud systems.

Start dates

• Middle .NET Software Engineer: September 1, 2026
• Senior .NET Software Engineer: September 17, 2026

Responsibilities:

• Design, develop, and maintain cloud-native applications and backend services using C# and .NET
• Build and support Web APIs and background services
• Work with Azure services such as Service Bus, Key Vault, Azure Storage, Cosmos DB, and Redis
• Investigate, troubleshoot, and mitigate production issues
• Improve service reliability, performance, and maintainability
• Apply secure coding practices throughout the development lifecycle
• Participate in technical discussions, code reviews, and engineering improvements
• Collaborate with engineers across international teams

Requirements:

• Strong commercial experience with C# and .NET
• Experience developing production-grade backend applications
• Hands-on experience with Microsoft Azure
• Experience with Web APIs and cloud-native / distributed applications
• Practical knowledge of several Azure services, such as:
  • Service Bus
  • Key Vault
  • Azure Storage
  • Cosmos DB
  • WebJobs
• Experience working with Redis or similar caching technologies
• Ability to diagnose and troubleshoot production service issues
• Understanding of secure coding practices and application security
• Good problem-solving and communication skills
• English sufficient for working in an international engineering environment

Nice to have

• Experience with Azure security, identity management, or compliance tools
• Experience with platform or infrastructure security
• Experience with host attestation or compute firewall management
• Experience building or configuring monitoring, anomaly detection, alerting, or automated incident-triage solutions
• Experience using AI/ML for security monitoring or threat detection

DRI / On-call schedule

The team provides production support through a rotating DRI (Directly Responsible Individual) schedule.

DRI shifts are planned to start in mid-January 2027.

• Each engineer will have a 1-week DRI shift approximately every 4 weeks
• Offshore engineers cover 8:00 PM – 8:00 AM PST
• During a DRI week, the engineer’s regular 8 working hours should fall within the corresponding 12-hour coverage window. These 8 hours are part of the regular working schedule and are covered by the normal salary
• The remaining 4 hours are on-call and are compensated at 0.5x
• If active incident resolution is required during those 4 on-call hours, that time is compensated at 1.5x
• For DRI coverage on non-working days, the same coefficients apply: 0.5x for on-call time and 1.5x for active incident resolution
• Only urgent incidents require attention outside regular working hours. The client does not expect such incidents to occur frequently
• Non-urgent incidents should be handled during normal working hours

This setup means that DRI is a rotational responsibility rather than a permanent night schedule, with one DRI week approximately every four weeks.

Benefits:

• Paid vacation and sick leave
• Official state holidays — 9-11 public holidays per year
• Professional growth through challenging projects and the opportunity to master new technologies
• Flexible working schedule: 8 hours per day, 40 hours per week
• Personal Career Development Plan (CDP)
• Employee support programs (discounts, healthcare, legal assistance)
• Paid external training, conferences, and professional certifications aligned with business goals
• Internal workshops, seminars, and English classes
• Corporate library with paper and e-books
