Collaborate with data science, research, engineering, design, and product teams to deliver reliable cybersecurity insights. The role emphasizes scalable software development, data quality, continuous improvement, and strong communication.

Lead architecture and hands-on development of scalable backend systems and APIs supporting real-time applications at massive scale. Own the full engineering lifecycle, establish standards for reliability and testing, troubleshoot production issues, influence technical roadmaps, collaborate cross-functionally, and mentor engineers. The role requires deep backend development, distributed cloud systems, system design, automated testing, and technical leadership experience.

Design and implement Mojo language features, compiler optimizations, and multi-target compilation for CPUs, GPUs, and AI accelerators using MLIR and LLVM. Collaborate with kernel authors, hardware engineers, researchers, and the open-source community to improve language design, code generation, performance, developer experience, and the broader Mojo SDK.

Administer and modernize enterprise Microsoft SQL Server platforms supporting downtime-sensitive semiconductor and telecommunications manufacturing. Responsibilities include advanced T-SQL and SSIS development, performance tuning, backup and disaster recovery, high availability, security, automation, migrations, cloud adoption, capacity planning, incident response, and database architecture. The role provides technical leadership, mentoring, documentation, and cross-functional guidance in 24/7 production environments.

Build and own production entity-resolution capabilities, including blocking, candidate generation, pairwise scoring, clustering, threshold policies, deduplication, and known-entity checks. Develop provenance systems for traceable, explainable graph relationships and matching decisions. Evaluate matching performance, document implementation logic, and balance false merges against false splits. Work remotely with occasional travel while supporting government mission applications.

Design, develop, test, and deploy supply chain software for inventory, warehouse, and fulfillment systems. Lead technical decisions, mentor engineers, coordinate cross-functional Agile projects, decompose work, delegate tasks, and promote strong development and testing practices. Build monitoring systems that ensure business-process correctness and support high-volume, data-intensive applications.

Design, develop, test, and maintain enterprise-scale healthcare software using C#, .NET, RESTful APIs, SQL Server, and modern JavaScript frameworks. Build scalable features, optimize databases, address concurrency issues, debug complex systems, contribute to architecture decisions, and support the full software development lifecycle. Collaborate with distributed cross-functional teams while helping modernize infrastructure through AWS migration, microservices, and cloud technologies.

Develop and maintain full-stack TypeScript applications using React, Node.js, and PostgreSQL. Build intuitive user interfaces, scalable APIs, and secure systems; collaborate on architecture, code reviews, testing, deployments, incident response, and infrastructure improvements. Mentor engineers, reduce technical debt, participate in Agile ceremonies, and support production systems in a remote-first environment.

Hands-on fellowship for university students and recent graduates interested in AI, backend engineering, cloud infrastructure, and software delivery. Fellows may research technology trends, build internal tools and automation workflows, explore LLM-powered agents, prototype backend or cloud solutions, and prepare technical documentation and client-readiness materials. The role emphasizes ownership, reliability, clear technical communication, and practical project experience.
