Senior Software Engineer - MDASH

Design, build, and evolve the MDASH scanning engine, including agent orchestration, multi-model routing, code understanding, vulnerability detection, reachability validation, and fix generation and verification. * Extend the engine's coverage across vulnerability classes, programming languages, frameworks, build systems, and codebase sizes, from single services to large monorepos. * Integrate program analysis techniques into agent workflows to make detections more precise and grounded. These include static and dynamic analysis, taint tracking, call-graph and data-flow analysis, fuzzing, and sandboxed execution. * Improve the engine's precision, recall, consistency, and fix quality, working from evaluation results, research findings, and production feedback. * Optimize scan performance, scalability, cost, and latency so MDASH works well on enterprise-scale codebases and in CI/CD workflows. * Build a secure, reliable, observable engine, with strong isolation for running untrusted code and clear telemetry for diagnosing agent behavior. * Work with security research, applied science, model, and product teams to bring new techniques and models into the engine quickly and safely. * Track the agentic security and code-scanning landscape, and bring forward ideas that make MDASH stand out against competitors. * Write high-quality, well-tested code. Lead design reviews, take part in code reviews and on-call rotations, and help raise the engineering bar for the team. Bachelor's degree in Computer Science or a related technical field AND 8+ years of technical engineering experience coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, TypeScript, or Python ○ OR Master's degree in Computer Science or a related technical field AND 6+ years of technical engineering experience coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, TypeScript, or Python ○ OR equivalent experience. * Experience building production systems with large language models, such as AI agents, multi-agent orchestration, tool calling, planning, context management, or code-understanding systems.

building or working on security scanners, static analysis (SAST), dynamic analysis (DAST), software composition analysis (SCA), compilers, or other program analysis tools. * Working knowledge of vulnerability classes such as memory safety, injection, authentication and authorization, deserialization, path traversal, SSRF, and business-logic flaws. * Experience with program analysis techniques such as taint analysis, data-flow and control-flow analysis, code property graphs, fuzzing, or symbolic execution. * Experience building distributed, high-scale cloud services on Azure, including containerized or sandboxed execution. * Familiarity with multiple software ecosystems and build systems across C/C++, C#, Java, JavaScript/TypeScript, Python, and cloud-native applications. A passion for developer experience, and for building tools that engineers trust and act on.
