The Role
We’re looking for a Senior. NET Engineer to join our team to help build scalable, secure, and high-performing enterprise solutions for the financial industry. As a Senior. NET Engineer, you will play a key role in designing, developing, and maintaining robust backend systems and APIs that power our core products. You’ll collaborate closely with frontend engineers, product managers, and QA teams to ensure seamless data flow, system reliability, and efficient service integration. Your contributions will include optimizing performance, enhancing system architecture, and applying best practices in software development, security, and deployment to support rapid and reliable product delivery.
Responsibilities
Operate as a product engineer focused on solving real user and business problems, not clearing a backlog. You bring ideas, challenge assumptions, and own outcomes
Work in an AI-first development flow. Use tools like Open AI Codex and Git Hub Copilot not just to go faster, but to do more: explore multiple approaches, validate ideas quickly, and build things that previously wouldn't have been worth the effort
Primarily focused on backend: designing, developing, and maintaining scalable services with. NET 10, ASP. NET Core, and Graph QL. Comfortable stepping into front-end work when the problem calls for it, since AI-assisted development means you don't need to be a specialist to ship quality UI
You're aligned to a product team and typically work alongside one or two other engineers on any given project, pairing on tough problems, reviewing each other's work, and shipping together rather than in parallel
Uphold a high quality bar. Engineers write their own tests at the unit, integration, and end-to-end levels, and every line of code, human-written or AI-assisted, is reviewed by a human before it ships
Drive technical improvements across the codebase. Proactively identify friction, propose changes, and see them through to adoption. Be a first responder for production. Use Data Dog, Grafana, Open Telemetry, and Microsoft Azure to quickly diagnose incidents, minimize impact, and harden the system against recurrence
