Senior Software Engineer

As a senior backend engineer, you will lead the design and development of scalable backend systems that power our platform. You'll collaborate with cross-functional teams to architect, build, and optimise high-performance services using. NET and C#. This role is ideal for engineers who enjoy solving complex technical challenges, driving architectural decisions, and mentoring other developers while delivering reliable, scalable systems.

Responsibilities:

• Take ownership of designing, developing, and delivering complex backend systems and features with minimal supervision.
• Translate business requirements into scalable Low-Level Designs (LLD) and contribute to architecture discussions across teams.
• Lead the end-to-end development lifecycle from design and implementation to deployment, monitoring, and optimisation.
• Build, maintain, and enhance high-quality backend services using. NET Core / ASP. NET Core and C#.
• Design and implement RESTful APIs, microservices, and distributed systems with scalability and reliability in mind.
• Collaborate closely with product managers, front-end engineers, QA engineers, and DevOps teams to deliver cross-functional initiatives.
• Mentor and guide junior engineers through code reviews, design discussions, and technical coaching.
• Identify system bottlenecks, architectural gaps, and technical debt; drive refactoring and modernisation initiatives.
• Ensure strong engineering practices through automated testing, documentation, CI/CD pipelines, and coding standards.
• Improve system observability and reliability using logging, monitoring, and debugging tools.
• Participate in on-call rotations and proactively troubleshoot production incidents while implementing preventive solutions.
• Contribute to a culture of innovation, ownership, and continuous improvement across engineering teams.

Requirements:

• 4+ years of experience building and scaling backend systems using. NET, ASP. NET Core, and C#.
• Strong understanding of object-oriented programming, design patterns, data structures, algorithms, and system design principles.
• Experience designing and building RESTful APIs, microservices, and distributed backend systems.
• Hands-on experience with SQL and NoSQL databases, including schema design, query optimisation, and performance tuning.
• Familiarity with caching, asynchronous processing, message queues, and event-driven architectures.
• Strong debugging and problem-solving skills with experience using observability and monitoring tools.
• Experience building highly available and scalable applications in cloud-based environments.
• Ability to work independently, drive technical decisions, and execute projects with ownership.
• Strong communication and collaboration skills across distributed teams.
• Experience mentoring engineers and contributing to engineering best practices.
• Familiarity with fintech, payroll, HR systems, payment integrations, or financial workflows is a plus.
• Exposure to Java-based ecosystems or polyglot environments is a plus.
