We are looking for an exceptional Senior / Principal Backend Engineer to join our AppSec Platform group, reporting directly to the Group Leader.
This is a highly autonomous, hands-on role for an engineer who wants broad technical ownership rather than a narrowly defined domain. You will work on some of AppSec's most important and challenging engineering problems - spanning high-scale distributed systems, data infrastructure, onboarding and integrations, developer experience, reliability, performance, and AI-driven engineering.
You will frequently operate across team boundaries, take ambiguous problems from idea to production, and lead technical initiatives that have an impact well beyond a single service or team.
We are looking for someone who combines deep backend expertise with strong execution: an engineer who can design the architecture, dive into the code, debug production systems, challenge existing assumptions, rapidly prototype new approaches, and bring others along with them.
Key Responsibilities:
Lead Critical Initiatives End-to-End - Own complex, business-critical engineering efforts from problem definition and architecture through implementation and production, often spanning multiple teams and domains.
Build and Scale the Backbone of AppSec - Design and evolve distributed systems and data infrastructure supporting large enterprise environments and hundreds of millions of entities, while balancing scalability, reliability, performance, and cost.
Stay Hands-On and Raise the Engineering Bar - Write and review production code, solve complex technical problems, and champion excellent architecture, maintainable code, testing, observability, and production ownership.
Drive Performance & Reliability - Identify architectural and operational bottlenecks and lead meaningful improvements in scalability, resiliency, efficiency, observability, and production readiness.
Shape DevEx and AI-Driven Engineering - Improve how engineers build, test, debug, and operate software while leveraging AI, automation, and agentic approaches to accelerate development and unlock new capabilities.
Requirements: 6+ years of hands-on backend software engineering experience, with demonstrated ownership of complex production systems.
Proven experience designing, building, and operating large-scale distributed systems in production.
Strong backend development skills in one or more modern languages such as TypeScript/Node.js, Go, Python, Java, or similar.
Strong experience with cloud-native architectures, preferably on GCP or AWS.
Hands-on experience with SQL and NoSQL databases and the ability to reason about data modeling, indexing, query performance, scalability, and operational trade-offs.
Experience using AI-assisted engineering tools as a meaningful part of the development workflow, combined with the engineering judgment to validate generated solutions and understand their trade-offs.
Excellent communication skills and the ability to influence technical decisions across teams and disciplines.
B.Sc. in Computer Science or an equivalent technical field, or equivalent practical / military experience.
Advantages:
Experience with Kubernetes, Docker, microservices, and event-driven architectures.
Experience with Infrastructure as Code, such as Terraform, Pulumi, or similar technologies.
Experience optimizing high-throughput or data-intensive production systems for performance and cost.
Experience building AI-powered features, agents, or agentic workflows.
This position is open to all candidates.
