# Member of Technical Staff — Company Building at Mirendil

- **Company:** Mirendil

- **Work type:** onsite
- **Posted:** 2026-07-14

## Job description

For engineers and scientists ready to build the company, not just the technology

Mirendil Mirendil is a tech-first company focused on solving core bottlenecks that unlock step-change acceleration across science and technology. Our first goal is to democratize frontier AI R&D across scientific disciplines. We are building a frontier AI research company and training our own models end-to-end.

## The Role

Every member of technical staff at Mirendil pushes the frontier. Most do it through research and engineering. This role does it by building the company itself. You'll operate as a force multiplier for the founders, sitting at the center of a frontier AI lab, owning founder priorities, ways of working, early customers, and special projects. The scope shifts with the company's priorities; the job is always the highest-leverage unowned problem. Your technical background is not a nice-to-have here. Our customers are researchers and engineers. Our product is frontier AI R&D itself. You'll speak fluently with ML researchers in the morning, translate that work into a compelling narrative for a design partner at noon, and improve our research organization's ways of working in the afternoon. You'll work directly with the CEO and co-founders on the highest-leverage problems in the company: you'll see every part of how a frontier AI company is built, funded, positioned, and scaled, from the inside.

## What You'll Own

- Founder leverage. Drive the founders' highest-priority initiatives while providing the day-to-day operational support that keeps them focused on what matters most: preparing for critical partner and investor conversations, coordinating priorities, and turning decisions into execution. You'll keep the founders on track and make sure their commitments don't slip.
- Zero to one with our first customers. Take our first customers from zero to one, then work with Business and Operations to scale the motions. Our buyers are highly technical; you will shape our positioning, land early design partners, and run pilots end-to-end.
- Company operating rhythm. Own the company operating rhythm. Build and run the systems that keep a research-driven company aligned and fast: planning cycles, goal tracking and internal KPIs, internal comms, and cross-team execution. You're the person who makes sure decisions get made, tracked, and followed through on across the team.
- Special projects. Jump on whatever is most important and least owned: a partnership negotiation, a launch, a market or technical landscape analysis, an operational fire.

## Who You Are

- Technically credentialed and technically credible. MS or PhD in CS, EE, physics, math, or another STEM field, plus a few years in industry as an engineer, scientist, or researcher. You can read a paper and credibly participate in an ML systems discussion, and hold your own with frontier researchers.
- Pulled toward the business side. You've felt the itch beyond your IC scope: maybe you drove a cross-functional initiative, ran the customer-facing side of a technical project, started something of your own, or found yourself doing the strategy work nobody asked you to do.
- A translator. Exceptional written and verbal communicator who can distill technical depth and ambiguity into crisp decisions and narratives for investors, partners, and customers.
- Structured and fast. You bring the analytical rigor of your technical training to messy, open-ended business problems: decomposing them, prioritizing ruthlessly, and executing fast.
- Extremely high energy and endurance. This is an intense, all-in role with long hours at a company moving at frontier-lab pace. You thrive on that, and you're at your best when the stakes and tempo are high.
- Bias toward action and low ego. You default to doing, you're relentlessly resourceful, and nothing is beneath you or above you.

We offer a base salary of $200,000–$350,000 USD and a meaningful equity grant, depending on experience and background, along with competitive benefits.

## About Mirendil

## Company Overview
- **One-liner**: Mirendil is building an AI system that automates AI research and development, with the goal of creating a self-improving loop that accelerates scientific discovery.
- **Entity Type**: Private (Seed stage; raised $200M)
- **Headquarters**: San Francisco, California, USA
- **Founded**: Early 2026
- **Founders**: Behnam Neyshabur and Harsh Mehta

## Core Business
- **Primary industry**: Artificial Intelligence / AI Research & Development
- **Target customers**: B2B – initially AI researchers and engineers, but eventually scientists and domain experts (e.g., biology labs, drug discovery teams) who need frontier AI capabilities without building a full AI lab.
- **Mission**: “Democratizing frontier AI R&D to accelerate science and technology.” The company believes self-accelerating AI R&D is the most direct path to solving humanity’s pressing problems.

## Products & Services
- **Mirendil Platform**: A proprietary AI R&D system that trains frontier models specialized in AI research tasks (e.g., experimental design, hyperparameter search, model evaluation, code writing, debugging). The platform is designed to autonomously loop over research and engineering problems, controlling its own GPUs and improving over time with minimal human input. **Status**: Not yet shipped; under development.

## Market Standing
- **Valuation**: $1 billion (as of June 2026 seed round)
- **Key Metric (Funding)**: $200 million raised in seed round – one of the largest AI seed rounds ever.
- **Notable Investors/Partners**: Andreessen Horowitz (co-lead), Kleiner Perkins (co-lead), NVIDIA (participant).
- **Growth Signals**:
  - Raised $200M at $1B valuation just months after founding.
  - Founding team of 20+ researchers and engineers recruited from Anthropic, xAI, Google DeepMind, and OpenAI.
  - Founders Behnam Neyshabur (co-inventor of SAM optimizer, ex-Google, ex-Anthropic) and Harsh Mehta (ex-Google, ex-Anthropic, initiated automated AI R&D efforts) have deep frontier AI experience.
  - Targeted at compressing research cycles from months to days.

## Competitive Advantages
- **Self-Accelerating Loop**: The product is not just a model but a system that improves itself – “the loop is the product.” This creates a compounding advantage if it works.
- **Singular Focus**: The entire company is rebuilt from scratch around AI doing AI research, unlike traditional labs that use AI as a tool.
- **Top-tier Talent Density**: With only ~20 people, the team includes some of the most accomplished young researchers from the leading AI labs.
- **Strategic Investors**: Backing from a16z, Kleiner Perkins, and NVIDIA provides credibility, capital, and potential infrastructure access.

## Strategic Focus
- **Immediate goal**: Build the system that can autonomously perform AI R&D, making frontier research accessible to non-AI experts.
- **Long-term vision**: Democratize frontier AI R&D so that any lab (drug discovery, chemistry, biology, robotics) can leverage it without becoming a frontier AI lab themselves.
- **Current priorities**: Train models exceptional at AI research; build infrastructure for automated experimentation, evaluation, and iteration; keep the team small and high-compound.

## Why Work Here
- **Engineering culture**: “Small team, singular focus. We hire to compound, not to grow.” The team of ~20 operates with high autonomy and ownership.
- **Cutting-edge work**: Opportunity to work on one of the most ambitious AI projects – automating the very process of AI research.
- **Team composition**: Colleagues from Anthropic, xAI, DeepMind, OpenAI; founders known for foundational contributions (SAM optimizer, Blueshift/Mirerva).
- **Work environment**: Based in San Francisco; likely in-office given the intensity of the work (remote/hybrid policy not publicly detailed).
- **Notable perks**: Direct exposure to frontier model training and infrastructure; chance to shape a company from its earliest stage.
