Opportunities in United Kingdom

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Lead Software Engineer (.NET) based in United Kingdom. This role offers the opportunity to lead a major modernization initiative within a globally distributed engineering environment. You will take ownership of the transition from a legacy monolithic architecture toward scalable microservices, guiding the process from analysis through production release. As a technical leader, you will influence architecture, resolve complex backend and data challenges, and help ensure reliable delivery. You will collaborate closely with Product and Architecture teams to translate business requirements into realistic technical plans. Beyond hands-on engineering, you will strengthen team processes, delivery discipline, quality practices, and engineering performance. You will also play an important people leadership role through coaching, feedback, and career development.

Own the end-to-end delivery of the monolith-to-microservices modernization initiative, from legacy system analysis and planning through production deployment, while maintaining visibility into delivery status, dependencies, and risks. Partner with Product and Architecture teams to review business and technical specifications, identify legacy dependencies, assess feasibility, and develop realistic engineering estimates. Guide architectural decisions across .NET Core services, SQL and NoSQL databases, and frontend integrations, ensuring solutions are scalable, maintainable, and aligned with product objectives. Serve as the primary technical escalation point for complex backend implementation challenges, data migrations, performance issues, and production incidents. Improve engineering delivery practices through stronger Jira task management, more accurate estimation, clear process discipline, and effective collaboration with QA teams. Support predictable, high-quality releases by identifying delivery risks early, coordinating resolution of technical issues, and maintaining strong production stability. Conduct regular one-on-one meetings connected to individual career goals, provide meaningful feedback, and support performance development and team engagement. Drive continuous improvements to engineering processes, collaboration practices, and team effectiveness. Requirements: Strong professional background in .NET engineering, with deep expertise in C#, .NET 8, and ASP.NET Core. Strong understanding of web application architecture, REST APIs, microservices patterns, and message brokers such as RabbitMQ. Solid database design and development experience with PostgreSQL, Microsoft SQL Server, and Redis. Practical experience modernizing legacy systems, including refactoring monolithic applications into microservices architectures. Experience with containerized environments and technologies such as Docker and Kubernetes. Ability to diagnose and resolve complex technical challenges involving application architecture, implementation, data migration, performance, and production systems. Proven experience leading engineering teams, including conducting one-on-one meetings, performance reviews, objective evaluations, and career development discussions. Strong delivery management skills, including Jira-based task tracking, estimation, process discipline, prioritization, and meeting internal delivery commitments. Experience reviewing business specifications, evaluating technical feasibility, preparing high-level estimates, and partnering with Product and Project Management teams. Strong communication and collaboration skills, with the ability to balance hands-on technical leadership with people and delivery management. Benefits: Full-time remote opportunity. Initial compensation level or salary range shared with candidates during the recruitment process and before employment begins. 28 calendar days of vacation per year. 7 wellness days per year that can be used for personal recovery, household matters, or other needs without using sick leave. Bonuses of up to $5,000 for successful employee referrals. 50% reimbursement for professional training, international conferences, and professional meetings. Corporate discounts for English-language lessons. Health support of up to $1,000 gross per year per employee when corporate medical insurance is not available, which can be used toward personally purchased health insurance or eligible medical expenses for the employee and close relatives. Workplace equipment and workspace support, including reimbursement of up to $1,000 gross once every three years for eligible home-office or coworking expenses. Internal gamified recognition system where colleagues can award bonuses that can be exchanged for merchandise, team-building activities, massage certificates, and other rewards.
