AI Platform Backend Software Engineer

Quick Facts

Backend engineer role focused on rebuilding software delivery as AI agents increase code volume.

In-person requirement: NYC HQ (Union Square).

Description

Own the path from commit to production for build, test, review, deployment, and security systems. Treat development infrastructure as a product—measure bottlenecks, build tools engineers want, and ship improvements across AI video products and the developer platform. Implement CI/CD, agent-based review, and automated security to help engineers and their agents ship quickly and safely.

Responsibilities

• Ship features across video creation software, video rendering engine, and developer platform; identify where development systems slow teams down.
• Turn friction insights into tools, agents, and streamlined workflows.
• Rebuild CI/CD for 100x change volume with fast incremental builds, test selection, flaky-test detection/quarantine, merge queues, and preview environments.
• Make deployments safe with progressive rollouts, automated canary analysis, feature flags, and automatic rollback.
• Own agent working environments (sandboxes, ephemeral stacks) and tooling for agents to build, test, and verify.
• Build an AI code review pipeline with agent reviewers, risk-based routing to humans, and automated policy checks.
• Run continuous agent-driven penetration testing against applications, APIs, and infrastructure; convert findings into PRs with proposed fixes.
• Integrate security into the development pipeline: secrets, dependency, and supply-chain scanning, AI-assisted vulnerability triage, and automatically generated fix PRs.
• Secure agent access using least-privilege permissions, short-lived credentials, sandboxing, audit logs, and prompt-injection guardrails.
• Measure and improve the development lifecycle (e.g., reduce PR-to-production time, replace long-lived credentials, drive flaky tests close to zero).

Requirements

• 5+ years of professional experience building backend or full-stack software with end-to-end shipping experience.
• Product sense and ability to apply it to infrastructure used by engineers and agents.
• Hands-on experience with CI/CD, cloud infrastructure, or security; drive to go deep.
• Extensive use of coding agents; informed opinions on where they break.
• Strong security instincts and ability to anticipate attacks while building.
• Practical, measurement-driven approach to improve the development lifecycle.
• Ability to own build, deployment, review, and security together and define roadmaps.
• Interest in shipping to production weekly and staying close to product.
• Preference for making the right path easy with useful tools and thoughtful defaults.

Benefits

• Comprehensive medical, dental, and vision plans.
• 401(k) with employer match.
• Commuter Benefits.
• Catered lunch multiple days per week.
• Dinner stipend for late work.
• Grubhub subscription.
• Health & wellness perks: team offsites, monthly team events, generous PTO.
