Software Engineer - Backend

Genesis10 is seeking a Sr. Software Engineer for our client in the Inventory Solutions arena. This is a 6+ month Contract opportunity located in Plano, TX, 75024

Description: Software Engineer - Backend
We are looking for a highly experienced Staff Backend Engineer to join our
engineering team. In this role, you will drive the technical direction for critical backend
systems, focusing on scalable, distributed architectures using C#.NET, MSSQL Server, and
various data backends. You will tackle complex, ambiguous problems across multiple
teams, ensuring our systems are robust, performant, and aligned with business objectives.
As a Senior Engineer, you will operate as a technical leader, mentoring others, influencing
roadmaps, and delivering high-impact solutions in a collaborative environment.

Key Responsibilities

• Lead the design and implementation of large-scale backend services and APIs using C#.NET, integrating with MSSQL Server and other data stores (e.g., NoSQL databases, caching layers like Redis).
• Architect distributed systems with eventual consistency models, ensuring high availability, fault tolerance, and scalability to handle massive traffic and data volumes.
• Apply domain-driven design (DDD) principles to model complex business domains, defining bounded contexts, aggregates, and entities for maintainable and evolvable systems.
• Drive technical road mapping, scoping, and prioritization for strategic initiatives, collaborating with product, design, and cross-functional teams to align on goals and trade-offs.
• Identify and resolve performance bottlenecks, optimizing for latency, throughput, and resource efficiency in high-load environments.
• Mentor and guide mid-level and junior engineers through code reviews, design discussions, and knowledge sharing, fostering a culture of engineering excellence.
• Influence engineering best practices across teams, including CI/CD pipelines, testing strategies, monitoring, and observability.
• Handle on-call responsibilities and lead incident response for production systems, proactively mitigating risks through architectural improvements.
• Stay abreast of industry trends in backend technologies, distributed computing, and data management, applying them to evolve our stack.

Must Haves

• 8+ years of professional software engineering experience, with at least 4 years focused on backend development in C#.NET or similar object-oriented languages.
• Deep expertise in relational databases like MSSQL Server, including schema design, query optimization, indexing, and stored procedures.
• Proven track record building distributed systems with eventual consistency (e.g., using event sourcing, CQRS, or saga patterns).
• Strong understanding of scalability techniques, such as sharding, partitioning, load balancing, and microservices orchestration.
• Hands-on experience with domain-driven design, including modeling domains, implementing repositories and enforcing invariants.
• Proficiency in modern backend tools and frameworks (e.g., ASP.NET Core, Entity Framework, Dapper).
• Experience with cloud platforms (e.g., Azure, AWS) for deploying and managing backend infrastructure.

Nice-to-Haves

• Experience integrating multiple data backends, such as combining SQL with NoSQL (e.g., MongoDB, Cosmos DB) or streaming systems (e.g., Kafka).
• Familiarity with containerization (Docker, Kubernetes) and serverless architectures.
• Contributions to open-source projects or publications on distributed systems, DDD, or backend scalability.
• Prior experience at a similar seniority level (e.g., Staff or Principal Engineer) in a fast-paced tech environment.
