## Description (the employer's text)

We are looking for a Senior Software Engineer to join our backend team and play a critical role in building the platform that will define CaseGuard’s next chapter.

You will design and build the REST API microservices and cloud infrastructure that power our application, real-time collaboration features, and large-scale processing workers.

This role is expected to operate with a high degree of ownership. You will take responsibility for backend domains or major features and drive them end-to-end from design through production with minimal oversight.

Beyond writing excellent code, you will contribute to engineering standards, influence system design, and help scale both the system and the team.

### What You Will Do

- Design and build scalable, secure REST APIs and microservices using ASP.NET Core (C#)
- Build and maintain backend workers for large-scale file processing - ingesting, analyzing, redacting, and exporting documents using ML models
- Take ownership of backend domains or major features and drive them end-to-end from design through production
- Own database design, schema decisions, and query optimization for production systems
- Design and deploy AWS cloud infrastructure using Infrastructure as Code (IaC) tools such as AWS CDK
- Support real-time collaboration features for concurrent multi-user workflows
- Identify and resolve performance bottlenecks to ensure reliability and scalability under load
- Champion security and compliance best practices across backend systems and APIs
- Work closely with frontend engineers to design and deliver end-to-end features - defining API contracts, aligning on data flows, and ensuring correct system behavior across client and backend
### Ownership & Execution

- Break down complex, ambiguous problems into well-defined tasks and execution plans
- Take ownership of ambiguous problem spaces and turn them into clear, executable designs and deliverables
- Operate with minimal guidance on implementation details while aligning with the overall architecture
- Drive execution across engineers when required - breaking down work, aligning implementation, and ensuring delivery outcomes
- Make independent technical decisions within your domain, escalating only when cross-system tradeoffs are involved
- Drive backend decisions in cross-functional work, ensuring system design is robust, scalable, and not constrained by client-side limitations
- Be accountable for the reliability, performance, and scalability of the systems you build in production
### Team Contribution

- Conduct thorough code reviews and uphold engineering standards
- Participate in architectural discussions and contribute to system design decisions
- Mentor junior engineers and support their technical growth
- Contribute to hiring by reviewing technical assessments and interviewing candidates
### Qualifications (Required)

- 6+ years of experience owning and delivering complex backend systems or features end-to-end
- Strong proficiency in C# and ASP.NET Core for REST API and microservices development
- Solid experience with relational and/or NoSQL databases and performance optimization
- Hands-on experience with AWS services (e.g., EC2, S3, Lambda, RDS, DynamoDB)
- Experience building scalable, production-grade systems with clear reliability and performance considerations
- Strong understanding of asynchronous processing, concurrency, and distributed system fundamentals
- Security-aware mindset with experience handling sensitive or compliance-regulated data
- Strong communication skills and ability to collaborate effectively across a hybrid team
### Qualifications (Preferred)

- Experience building large-scale file or document processing pipelines
- Experience with event-driven architectures and message queues (e.g., SQS, SNS, EventBridge)
- Familiarity with ML model integration or AI-powered backend systems
- Experience with real-time systems (e.g., WebSockets, SignalR)
- Practical knowledge of IaC tools such as AWS CDK, Terraform, or CloudFormation
- Experience with containerization (Docker) and orchestration platforms (Kubernetes)
- Relevant AWS certifications
