We are seeking an experienced Senior Software Engineer and engineering excellence champion, with expertise in advanced object-oriented programming and related concepts (OOP to DDD), with extensive experience in web development frameworks and cloud technologies.

The candidate will be responsible for high-volume, enterprise-critical systems and will still be actively coding 60-70% of the time while guiding team execution.

Key Responsibilities

Lead the design and development of complex, scalable web solutions using object-oriented programming principles and technologies such as .NET (C#) and React (TypeScript).
Champion engineering excellence through clean, testable code and comprehensive unit testing. Promote test-first methodologies, including test-driven development (TDD) and behavior-driven development (BDD).
Provide technical leadership for high-volume, complex workflows; take ownership of troubleshooting, performance optimization, and problem-solving while mentoring the team and helping prioritize competing tasks.
Execute technical spikes and proof-of-concepts (POCs) to validate architectural decisions and design approaches.
Conduct thorough code reviews and provide constructive, actionable feedback.
Serve as a sounding board for cross-functional discussions, particularly on how backend decisions impact mobile and frontend implementations.
Collaborate with product managers, architects, UX designers, and other stakeholders to define and implement software functionality, architecture, and system design.
Drive the adoption of security best practices and mentor team members in secure coding techniques.

Required Qualifications

Bachelor’s degree in software engineering or a related field.
7+ years of experience in software development, including 4+ years working on commercial software products.
Expert-level proficiency in .NET (C#) and strong competency in React (TypeScript), with deep understanding of OOP principles and design patterns.
Experience with relational databases (e.g., PostgreSQL) and ORM frameworks such as Entity Framework Core.
Hands-on experience with CI/CD pipelines (e.g., GitLab CI/CD) and DevOps practices.
Familiarity with microservices architecture and containerization tools (e.g., Docker, Kubernetes).
Working knowledge of cloud platforms (e.g., AWS).
Strong foundation in software architecture and system design, including concepts from Domain-Driven Design and Patterns of Enterprise Application Architecture.
Strong leadership and mentorship skills, with the ability to guide a team while remaining hands-on, promote high-quality coding practices, and support unit testing and TDD implementation.
Proven ability to manage multiple priorities in a complex, high-volume product environment.
Proficiency in developing and consuming RESTful APIs.
