Commitment: Contract

Workplace Type: remote

Accountabilities:

• Lead backend architecture decisions while maintaining a pragmatic balance between simplicity and scalability.

• Design, develop, and deliver backend features end-to-end using modern engineering practices and production-ready standards.

• Strengthen CI/CD pipelines using tools such as GitHub Actions or Jenkins, supporting containerized builds and deployments via Helm on AWS infrastructure.

• Improve system reliability through observability tools, including monitoring latency and error budgets with CloudWatch and Grafana, and implementing structured logging and tracing where needed.

• Optimize system performance by refining database indexing, caching strategies, queue throughput, and API response times.

• Implement lightweight security measures such as rate limiting, IP allowlists, and abuse detection mechanisms.

• Conduct code reviews, enforce development standards, and maintain strong branching and release management practices.

• Break down technical initiatives into actionable tasks, provide accurate estimations, and remove blockers for the engineering team.

• Mentor engineers and promote a culture of accountability, clarity, and high technical standards.

Requirements:

• Proven experience building and maintaining production-grade backend systems, including at least 3 years in backend development and 2 years in a technical leadership or ownership role.

• Experience working with databases and caching technologies such as PostgreSQL, Redis, and MongoDB.

• Familiarity with OpenAPI 3, modern CI/CD pipelines, and containerized development workflows.

• Experience with event-driven and asynchronous architectures using tools such as SQS, EventBridge/Lambda, Celery, or similar queuing systems.

• Hands-on knowledge of production operations, including Docker, monitoring tools, incident response, and infrastructure deployments.

• Solid understanding of security best practices, RBAC models, authentication/session management, and OWASP principles.

• Ability to document technical decisions clearly, balance engineering trade-offs, and collaborate effectively with stakeholders.

• Upper-intermediate English proficiency or higher.

• Fluency in Ukrainian and/or Russian.

• Additional experience with automation platforms, RPA environments, AI-enabled systems, or Python backend frameworks such as FastAPI or Flask is considered a plus.

Benefits:

• Competitive compensation package based on experience and expertise.

• Opportunity to lead backend architecture and influence technical direction in a high-impact environment.

• Flexible and collaborative work environment with a focus on innovation and engineering excellence.

• Exposure to modern cloud infrastructure, distributed systems, and scalable backend technologies.

• Professional development opportunities and the ability to mentor and shape engineering culture.

• Remote work flexibility and a globally distributed team environment.
