Job Title: Senior Software Engineer – AI Security

Role Overview
We’re looking for a talented mid-level engineer to design, build, and enhance tooling and intelligent systems that support safe, resilient AI workflows. You’ll contribute to platforms that empower teams to embed safe logic, enforce secure behavior, and maintain operational quality across distributed systems using advanced chunking, agent orchestration, and trustworthy code pipelines. You will work with engineers across product, security, and infrastructure to deliver solutions that raise the bar on reliability and safety in intelligent software delivery.

What You’ll Do

• Design and implement components for AI-enhanced tooling that monitors, evaluates, and improves software behavior with an emphasis on safety and resilience across distributed systems.

• Build and maintain systems that leverage semantic chunking, language model agents, and automated reasoning to support developer workflows with contextual awareness and guidance.

• Collaborate with cross-functional teams — product, security, SRE — to translate high-level needs into technical designs and robust implementations.

• Contribute to safe AI practices by defining interfaces and logic that help prevent and detect unsafe code constructs or misconfigurations without relying on simple pattern matching.

• Partner with DevOps and CI/CD engineers to integrate quality feedback loops, instrumentation, and runtime guards into build, deploy, and release pipelines.

• Participate in design reviews, code reviews, and retrospectives that drive continuous improvement of our AI-infused systems.

• Investigate issues in distributed environments, propose solutions, and deliver fixes that enhance maintainability, performance, and safety.

• Help define best practices for code health, observability, and monitoring in intelligent pipelines.

Who You Are

• 8–15 years of software engineering experience with a solid foundation in languages such as Python, Go, or TypeScript.

• Strong understanding of distributed system design, asynchronous workflows, and microservices architectures.

• Experience or strong interest in AI/ML concepts, especially in applying models to assist developer tooling or runtime analysis.

• Familiarity with modern cloud environments (AWS, GCP, Azure) and container orchestration (e.g., Kubernetes).

• Comfortable working with APIs, message buses, and streaming data (e.g., Kafka, Pub/Sub).

• Practical knowledge of secure development practices, runtime policy enforcement, and defensible system design without being limited to “scan and flag” strategies.

• Experience integrating or building systems that use semantic chunking or structural representations of code/data is a plus.

• Excellent collaborator who communicates clearly and contributes to team success.

Nice to Have

• Hands-on experience with LLMs, agent frameworks, or developing smart assistants that operate in software contexts.

• Background in building developer productivity tools or platform services.

• Understanding of formal methods, symbolic analysis, or safety-constrained execution environments.

• Experience with observability tooling (metrics, logs, traces) and runtime dashboards that support operator understanding.
