Description

About Backslash

We are builders who want to secure the next generation of software development from the inside out.

Software development has entered a new era defined by Vibe-coding, MCP servers, and AI Agents. While these tools allow developers to build faster than ever, they also introduce a completely new frontier of security challenges that exist directly on the engineer's machine.

Backslash is building the security layer for this new reality. We provide the essential guardrails and visibility needed to secure AI-driven workflows. By actively protecting developer computers and monitoring IDE-based AI interactions, we ensure the future of coding is as secure as it is fast. 

The Role

As an Engineer, you will be responsible for the infrastructure that connects our local protection agents to our high-scale cloud backend.

• Architect Distributed Systems: Design and evolve a robust microservices architecture capable of handling high-throughput telemetry and security events from thousands of distributed developer machines.
• Master Endpoint Deployment: Own the delivery and lifecycle of our protection agent, ensuring it deploys seamlessly to engineer laptops and runs with a zero-friction resource footprint.
• Scale Data Infrastructure: Build the backend pipelines and storage solutions that ingest, process, and provide visibility into real-time security data from IDEs and local AI tools.
• Deliver Full-Stack Features: Take end-to-end ownership of features, contributing to the user interface to ensure backend data and endpoint health are presented clearly to our users.
• Drive Technical Excellence: Set the standard for stability through automated quality gates and a commitment to building low-latency, resilient software that developers can trust on their machines.

Requirements

We’re looking for a backend specialist who thinks in systems and data flow but can navigate the full stack when the feature requires it.

• Engineering Depth: 5+ years of software engineering experience, with a track record of shipping complex backend systems or distributed architectures.
• Micro-services Mastery: Hands-on experience designing and maintaining microservices in production, including service discovery, inter-service communication, and high-scale data ingestion.
• Backend Expertise: Highly proficient in server-side development using modern ecosystems (like NestJS, Adonis etc.) and a strong command of TypeScript/Node.js.
• Full-Stack Capability: Practical experience with modern frontend frameworks (like React or Vue). You are comfortable building UI components to visualize the telemetry and insights of backend processes.
• Cloud Native: Strong experience with containerization (Docker, Kubernetes) and major cloud platforms (AWS, GCP, or Azure).
• Startup DNA: You thrive on ownership. You want to solve problems, not just execute tasks.

Bonus points for

• Endpoint & Systems: Familiarity with building software that runs locally on macOS, Linux, or Windows (background agents, daemons, or system services).
• Cybersecurity Interest: Experience in EDR/XDR, endpoint protection, or a deep interest in securing developer workflows.
• Data Scale: Experience designing and implementing complex algorithms or high-performance data pipelines.
