Sr. Software Engineer

Essential Job Functions

• Architect, design, implement, test, and operate backend services using .NET (preferably in F#).


• Design and evolve APIs with clear contracts, versioning, and documentation.


• Build and maintain event-driven data pipelines using Kafka (producers, consumers, stream processing).


• Design and operate systems for high-volume, near real-time event processing: partitioning, parallelism, low-latency processing, backpressure, batching, windowing, and stateful stream processing.


• Implement or collaborate on front-end features as needed; work with front-end engineers to deliver end-to-end solutions.


• Deploy and operate services on AWS


• Apply domain-driven design and functional programming patterns where appropriate to produce maintainable, testable code.


• Collaborate with product, QA, and DevOps on requirements, CI/CD, observability, and incident response.


• Mentor and review code, drive engineering best practices, and conduct architecture reviews.


• Optimize for performance, scalability, reliability, and cost in production systems. 


• Other duties as assigned.

Technical Expertise

• 6+ years professional experience in backend development with the .NET ecosystem.


• Substantial experience writing production code in F# and C# (practical experience applying functional programming in systems).


• Some front-end development experience (modern JavaScript/TypeScript, React/Angular/Vue, responsive UI, or component-driven design).


• Hands-on experience with Apache Kafka: designing topics, partitions, consumer groups, idempotent producers, and at-least-once/exactly once patterns.


• Demonstrated experience designing and implementing high-throughput, low-latency event processing systems (e.g., sub-second to few-seconds end-to-end latency, handling thousands to millions of events per minute).


• Practical Azure experience (deploying, monitoring, and operating services — e.g., AKS, App Services, Functions, Storage, SQL, Managed Identities)


• Strong API design experience (RESTful or gRPC): versioning, documentation (OpenAPI/Swagger), authentication/authorization (OAuth2/OpenID Connect).


• Solid understanding of distributed systems concepts: messaging, consistency, retries, backpressure, windowing, state management, and eventual consistency.


• Experience with CI/CD pipelines, automated testing (unit/integration), and observability (metrics, tracing, structured logs).

Preferred Qualifications

• Experience with stream processing frameworks (Kafka Streams). 


• Familiarity with Infrastructure-as-Code (ARM, Bicep, Terraform). 


• Experience with container orchestration. 


• Experience designing for multi-tenant or high-throughput systems. 

Physical Requirements

• Job may require extended sitting or standing, use of standard office equipment.


• Job requires the ability to use vision, adjust focus and work on a standard computer screen.


• Use of audio-visual equipment is required.

Education & Experience

• Bachelor’s degree in Computer Science, Information Systems, or a related technical field preferred, or equivalent hands-on experience.


• High School Diploma or GED equivalency required.


• 6+ years professional experience in backend development with the .NET ecosystem.

Certification and Licenses

• Professional certification may be required in some cases
