8090 Solutions, co-founded by Chamath Palihapitiya, is building a Software Factory that orchestrates the end-to-end software development lifecycle and delivers fully managed, hosted software tailored to each customer's needs. The company is tackling the problem of enterprise software being too expensive, complex, and difficult to change.
You will serve as Engineering Lead for the Software Factory agent, a builder-leader role combining deep agent expertise with the ability to build and scale an exceptional engineering team. You will remain hands-on in the code while collaborating with product management to translate ambitious capabilities into dependable customer experiences.
Key responsibilities include:
- Own agent architecture across multi-agent orchestration, agent harnesses, prompt and context design, retrieval-augmented generation (RAG), memory, tools, and execution environments. Lead architecture reviews and make tradeoffs between capability, complexity, latency, and cost.
- Work with product management on agent capabilities and user experience, then own engineering delivery. Translate the shared roadmap into technical plans, milestones, and dependencies; focus the team on the highest-impact work and remove blockers.
- Regularly write and ship production code, lead code reviews, and solve difficult technical problems alongside engineers. Build capabilities for reasoning about code, working across repositories and development tools, and interacting with browsers and computer environments.
- Develop engineers' technical judgment, help recruit exceptional talent, and establish effective planning and review practices. Clarify ownership, resolve technical disagreements, and build a team that coordinates well and takes accountability for outcomes.
- Make agent behavior observable and debuggable, with reliable recovery and escalation when tasks fail. Use production traces, experiments, and customer feedback to improve task completion, output quality, reliability, latency, and cost.
- Partner with security and infrastructure engineers on permissions, sandboxing, data boundaries, and controls for deploying and operating agents in production.
You will work in person five days a week from the Redwood City, CA office.
REQUIREMENTS:
- A record of shipping production agents with sustained, high-volume usage and measurable customer impact. You must be able to explain the decisions you owned, the failures you encountered, and the improvements you delivered.
- Deep practical expertise in LLM-based agent systems, including orchestration, context engineering, tool integration, memory, model selection, and evaluation.
- Strong software engineering fundamentals and demonstrated ability to build, debug, and operate complex production systems.
- Evidence of technical leadership and mentorship that improved other engineers' work. You communicate clearly, exercise sound judgment under ambiguity, and work effectively with product and engineering partners.
DESIRABLE EXPERIENCE:
- Direct experience building coding agents or browser/computer-use agents that complete complex tasks across tools and environments.
- Experience deploying agents in enterprise environments with demanding security, isolation, or customer-specific deployment requirements.
- Familiarity with post-training and reinforcement learning, including judgment about when they can improve agent behavior.
