Original job description

Kforce's client is looking to add a Senior Software Engineer to their team. This role is a 6-month contract to hire in Saint Louis, MO.

Summary:

Are you a back-end engineer who loves solving complex technical challenges at scale? Our client is seeking a Senior Software Engineer to design, build, and optimize the core services that power a high-volume platform. This role is focused entirely on back-end development using the Microsoft technology stack, including C#, .NET, SQL Server, and Azure.

This is an opportunity to work on highly performant, rules-driven systems where scalability, reliability, and code quality are critical. You'll partner with Product, QA, and Engineering teams to develop solutions that support complex business logic while helping drive architectural decisions and technical best practice.

What You'll Do:

Design, develop, and maintain back-end services using C#, .NET, ASP.NET Core, and Azure
Build and optimize high-performance APIs and services focused on scalability and reliability
Profile and tune application performance, including latency, memory usage, database efficiency, and throughput
Design cloud-native solutions leveraging Azure services, messaging, caching, and automation tools
Translate complex business requirements into clean, maintainable code and scalable architectures
Participate in code reviews, technical design discussions, and architecture decisions
Troubleshoot and resolve complex production issues in large-scale systems
Mentor other engineers and contribute to raising technical standards across the team
Leverage AI-assisted development tools to improve efficiency, quality, and delivery
Bachelor's degree in Computer Science, Software Engineering, or related field (or equivalent experience)
7+ years of professional software development experience
Experience optimizing application performance, identifying bottlenecks, and improving scalability
Advanced SQL Server experience, including query optimization and performance tuning
Experience developing and supporting cloud-based applications in Microsoft Azure
Strong expertise with C#, .NET, ASP.NET Core, and RESTful API development
Deep understanding of software design patterns, object-oriented design, and domain modeling
Strong understanding of automated testing, CI/CD pipelines, and DevOps practices

Preferred Qualifications:

Experience building high-throughput, low-latency applications
Experience with Infrastructure as Code and containerized deployments
Knowledge of distributed systems, caching strategies, messaging platforms, and event-driven architectures
Exposure to AI-assisted software development tools
Background in financial services or other regulated industries

Technology Stack:

C#
.NET/ASP.NET Core
Entity Framework Core
SQL Server
Microsoft Azure
Azure DevOps
REST APIs
CI/CD Automation

The pay range is the lowest to highest compensation we reasonably in good faith believe we would pay at posting for this role. We may ultimately pay more or less than this range. Employee pay is based on factors like relevant education, qualifications, certifications, experience, skills, seniority, location, performance, union contract and business needs. This range may be modified in the future.

We offer comprehensive benefits including medical/dental/vision insurance, HSA, FSA, 401(k), and life, disability & ADD insurance to eligible employees. Salaried personnel receive paid time off. Hourly employees are not eligible for paid time off unless required by law. Hourly employees on a Service Contract Act project are eligible for paid sick leave.

Note: Pay is not considered compensation until it is earned, vested and determinable. The amount and availability of any compensation remains in Kforce's sole discretion unless and until paid and may be modified in its discretion consistent with the law.

This job is not eligible for bonuses, incentives or commissions.

Kforce is an Equal Opportunity/Affirmative Action Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, pregnancy, sexual orientation, gender identity, national origin, age, protected veteran status, or disability status.
