Senior Software Development Engineer

US Software Solutions is a software development company focused on providing digital technologies to the Utilities, Telecommunications, Energy Efficiency, Renewable Energy, and Gas/Electricity sectors. Thanks to a team consisting exclusively of experts in their field, we are ready to supervise any project, regardless of its complexity and scale. We're hiring a Senior Software Development Engineer to own systems within it. How we work Our engineers work primarily as architects. Much of the implementation is produced through AI-assisted delivery tooling, which means your day is spent deciding what to build and how to structure it, specifying it precisely, reviewing the result critically, and going hands-on for the parts that require real depth. You will write less code than in a traditional senior role and be accountable for more of it. That only works if you know the patterns and the technology well — you cannot review what you don't understand, and reviewing is a large part of the job. Work schedule: Monday - Friday from 14:00 till 22:00 Own systems end to end: architecture, data model, API design, delivery, and production behavior. Propose and defend architectural decisions. Write specifications precise enough to be implemented without follow-up questions. Review code critically at volume and take ownership of the result. Go deep where automation falls short, query performance, spatial data handling, concurrency, and frontend rendering performance. Build and evolve map-based features that stay responsive on tablets in the field. Maintain shared internal libraries as versioned products used by other teams. Plan and execute database migrations against live systems. Set engineering standards for testing, code quality, and documentation. Mentor mid-level engineers. Work directly with product and business stakeholders on field workflows and push back when requirements don't hold up. 6+ years of professional software engineering, TypeScript-first, across React/Next.js and Node.js. Strong SQL - you can write complex queries directly and diagnose why one is slow. Production experience with an ORM on a large schema, including migrations against live data, and judgment about when to drop to raw SQL. Solid grounding in OOP, design patterns, and relational database design. Experience maintaining a shared internal package or SDK, versioning and managing breaking changes for other teams. Containers, Kubernetes, and CI/CD; comfortable owning a service in production. Demonstrable architecture judgment, you can walk us through a design decision, how it played out, and what you'd change. Experience shipping production code with AI coding tools, and the critical eye that comes with it. Fluent Russian, engineering collaboration happens in Russian. Professional English for documentation Competitive salary package; Being part of a international, dynamic work environment; Professional development (seminars, courses); Paid time off (PTO) such as sick days and vacation days;
