You’ll work at the intersection of software engineering and artificial intelligence , helping AI labs and companies build better, safer, and more capable models. This includes writing prompts, producing reference-quality code solutions, evaluating model outputs, and providing the structured human signal that makes AI systems smarter.

- Write functional and integration tests.
- Help ensure the quality of AI-generated software engineering outputs.

Core Requirements:

- 5+ years of professional software engineering experience in a backend, AppSec, or Security role.
- Strong proficiency in at least one core programming language, ideally Python (open to Rust, Go, and TypeScript as well).
- Hands-on experience with Terminal-Bench, including evaluating AI agent performance on terminal-based tasks.
- Comfortable working with Linux, Docker, and Git command line/terminal and common development workflows.
- Experience working with supply-chain,



vulnerability triage, security credentials, and access control.
- Strong experience writing functional and integration tests. Hands-on practitioners, not reviewers.
- Excellent written and verbal communication skills in English.
- Ability to work independently in a remote, fast-paced environment.

Nice-to-Have:

- Experience working on AI, machine learning, or LLM-related projects.
- Familiarity with software quality assurance methodologies or technical evaluation frameworks.
- Experience working with distributed systems or large-scale applications.

Additional Information:

- This is a unique opportunity for senior engineers interested in shaping how the next generation of AI understands, generates, and reasons about code.
- The role sits at the intersection of software engineering and artificial intelligence, helping AI labs and companies build better, safer, and more capable models.
- US Timezone Overlap: 6 hours preferred with PST time zone.
