About The Position
mpathic is seeking a Senior Software Engineer (Back End) to help design, build, and scale the systems that power our platform and AI safety work. This role will focus primarily on backend engineering using .NET (C#) and AWS, with responsibility for building reliable APIs, services, data infrastructure, and cloud-native applications. You’ll work closely with engineers and cross-functional partners to solve complex technical problems, improve the scalability and performance of our systems, and support the integration of AI models into our products and workflows. We’re looking for an experienced engineer who is comfortable owning problems end-to-end, making thoughtful architectural decisions, and operating in a fast-moving environment where the problems we’re solving are still evolving.
Requirements
- 5+ years of software engineering experience, with a strong focus on backend development using .NET (C#).
- Hands-on experience with AWS services, architecture, and best practices for building and operating cloud-native applications.
- Strong experience with SQL and NoSQL databases, including schema design, data modeling, query optimization, and performance.
- Experience designing scalable, reliable backend services, APIs, and distributed systems.
- Working knowledge of React and its ecosystem, with the ability to collaborate effectively across the stack.
- Comfortable taking ambiguous technical problems from initial requirements through design, implementation, testing, and deployment.
- Strong communicator who enjoys working across engineering, product, and other technical teams.
- Curious about emerging technologies and motivated to evaluate new tools and approaches pragmatically.
Responsibilities
- Design, build, test, and maintain robust backend systems using .NET (C#) and other languages as appropriate.

- Build reliable APIs and services that support mpathic’s platform, products, and AI workflows.
- Work with both SQL databases, including PostgreSQL, and NoSQL databases, including DynamoDB, to support diverse application and data needs.
- Make thoughtful architectural decisions around reliability, scalability, performance, security, and maintainability.
- Support the integration of AI models and AI-powered capabilities into production systems and workflows.
- Partner closely with frontend engineers and occasionally contribute to React-based applications when needed.
- Write clean, maintainable, well-tested, and well-documented code while contributing to engineering standards and best practices.
- Provide technical guidance to other engineers and actively participate in code reviews, architecture discussions, and knowledge sharing.
- Tackle complex engineering challenges spanning performance optimization, system design, troubleshooting, integrations, and evolving product requirements.
- Stay current on emerging tools and techniques for cloud infrastructure, services, APIs, and AI applications. Conduct focused proofs of concept with clear technical and business outcomes.
- Work closely with engineering, product, AI, and other teams to translate business and customer needs into scalable technical solutions.
