This means not only creating backups but also knowing:

• What is backed up
• How frequently backups are created
• Where they are stored
• How they can be restored
• How a failed production environment can be rebuilt
• How production can be recovered if a server becomes unavailable

Incident response

This is the only position in the team that includes responsibility for urgent production incidents outside standard working hours.

Production incidents outside working hours are not expected to be routine, but when a critical production service becomes unavailable, the DevOps Engineer must be reachable and able to respond.

We expect:

• Reliable availability during normal working hours
• Reasonable emergency availability outside working hours
• Fast acknowledgement of critical production incidents
• Ability to access and investigate production remotely when necessary
• Clear communication during an incident
• Notification to the team if you will be unavailable for a known period

• English: Intermediate or higher

What is important to us

Reliability and communication are critical for this role.

We expect the DevOps Engineer to:

• Be reachable during agreed working hours
• Respond to critical infrastructure incidents
• Notify the team about planned periods of unavailability
• Take ownership of production problems
• Investigate root causes rather than only restart services
• Communicate clearly with developers, QA, and the Project Manager
• Document important infrastructure knowledge
• Proactively identify risks
• Gradually reduce dependency on undocumented knowledge held by individual team members

Our goal is to build an infrastructure process where production knowledge, access, deployments, backups, and recovery procedures are documented and are not dependent on one person's memory.

We are looking for a Middle / Strong Middle Full-Stack Developer to join a newly forming technical team responsible for maintaining and developing existing CRM and web-based trading platform products.

The systems are already in production and used across multiple environments.

At the current stage, the majority of development work involves investigating and fixing existing issues, with additional product improvements and new functionality being introduced continuously.

This is not a role where every task comes with detailed technical implementation instructions.

We are looking for a developer who can gradually take ownership of issues and independently move from problem reproduction to root-cause analysis and implementation.

Previous experience in FinTech, Forex, CFD, or trading is not required. Product and business logic will be explained during onboarding.

What you will work with

The product environment includes:

• Web-based CRM
• Web-based CFD/trading platform
• Existing production codebase
• JavaScript-based web applications
• REST APIs
• WebSockets and real-time functionality
• Third-party integrations
• Multiple production environments
• GitHub-based development workflow

The existing codebase is complex and contains legacy functionality, so the ability to understand and debug unfamiliar code is important.

Responsibilities

• Investigate and fix bugs in existing CRM and trading platform functionality
