As a Member of Technical Staff at Indices, you will build the core infrastructure enabling AI agents to programmatically navigate the web. You will own features end-to-end, from designing hardened sandboxed runtimes to building developer-facing CLI tools. This role requires high agency to navigate ambiguity and solve challenging systems-level problems.
Member of Technical Staff at Indices
Indices is building the infrastructure that lets AI agents act across the web. Founded by experts from Starling Bank and Meta security research, the team is replacing brittle Selenium scripts with a high-performance, network-level solution that turns websites into deterministic APIs. As an early Member of Technical Staff, you will use Rust and Postgres to build hardened sandboxed runtimes and distributed telemetry systems. This is a high-agency role where you will work alongside exceptional engineers to solve the genuinely hard problem of computer use. If you are a deep-thinking engineer who loves systems programming and reverse engineering, join Indices to help build the next generation of AI infrastructure.

Role overview
Indices is a venture-backed infrastructure startup founded by security researchers and high-availability engineers from Meta and Starling Bank. They are building the platform that enables AI agents to use the web reliably and securely via network-level computer use, turning any website into a deterministic, programmable API.
What you will do
- Design and implement a hardened sandboxed runtime with minimal latency, secure credential injection, and multi-tenant isolation for AI agent execution.
- Build comprehensive tracing and telemetry across a highly distributed system to ensure reliability and auditability in complex, multi-layered sandboxed environments.
- Develop user-facing CLI tools and integrations optimized for popular coding agents to ensure a seamless onboarding experience for engineers building on Indices.
Who this is a fit for
- Demonstrates strong software engineering skills with proficiency in at least one backend language like Rust or Python, and a desire to build high-performance systems.
- Possesses a high-agency mindset, comfortable navigating technical ambiguity and owning projects from initial architecture through design, implementation, and long-term customer support.
- Has a background or strong interest in systems programming, security, or browser internals to tackle low-level challenges like reverse engineering and sandboxing.
Why this role is remarkable
- Join an elite technical team including a security researcher with CVEs in WhatsApp and Android, and engineers who built high-availability systems at Starling and Bloomberg.
- Work on the bleeding edge of AI infrastructure, replacing brittle browser agents with a high-performance, deterministic network-level solution that makes the web programmable.
- Exercise extreme ownership in a high-agency environment where you design core technology and influence the product roadmap from the earliest stages of the company.
