Founding Engineer

Let the Builders Build

Tier Zero’s mission is to accelerate software engineering. Today, engineers spend 50–70% of their time not building – chasing alerts, fighting fires, answering questions, and monitoring releases. We are building AI agents that take this work off their plate, unlocking creativity and speed. The opportunity is massive: a $1.5T productivity market waiting to be reclaimed.

Highlights

• Team
  :
  Our founding team is made up of pioneers in AI agents – staff and principal engineers who built foundational systems in the early days of Facebook, Databricks, Lang Chain, and Brex. CEO is a 2x founder with prior successful exits and owned cloud infrastructure at Pokémon GO. CTO was one of the first engineers at Databricks, where he led AI model serving and AI agent initiatives to $300M+ of revenue.

• Customers
  :
  We work with multiple enterprise engineering teams, all of whom have seen meaningful transformation in reliability and velocity, and consistently volunteer to act as customer references for us.

• Product
  :
  We’ve built an extensible agentic platform that unifies code, infrastructure, telemetry, and tribal knowledge. This provides full context across the entire engineering system to enable specialized AI agents for various tasks, from incident investigation to support engineering. In addition, we deliver accuracy at such a high level that we confidently provide the industry’s only 95% guarantee on agent outputs.

• Funding
  :
  We are backed by legendary investors including Accel and SV Angel, who are early investors in Facebook, Atlassian, Slack, and Stripe.

Background

Coding has become 10x easier with modern AI tools, yet engineering roadmaps haven’t gotten 10x faster. The bottleneck: alerts, incidents, support requests, deployments, performance issues, and the growing operational overhead of modern systems. Tier Zero solves this by deploying self-learning AI agents that handle these operational workflows end-to-end, giving engineers back their time and accelerating delivery.

We’ve helped customers achieve 46% higher uptime while saving over 10,000 engineering hours per year.

Company Values

• Everything is Figure-out-able :
  We approach every challenge with creativity, optimism, and the belief that great teams can solve anything. There’s always a move.

• High Agency
  :
  We value autonomy, thrive in ambiguity, and are energized by ownership. We trust each other to make bold decisions, move fast, and turn ideas into wins for our customers.

• Wrong Answers Only
  :
  We welcome imperfect ideas, early thoughts, and bold guesses, because truth emerges faster when no one is afraid to speak up. Low ego, open debate, and psychological safety let us uncover these truths and act with conviction.

• Anti-996
  :
  Over half our team, including both founders, are parents. We don’t believe in 996 culture; we believe the mission is served by the intensity of our work, not the hours. We give each other the flexibility to show up fully in both work and life.

Role

As a founding engineer, you’ll help invent and build the core product and systems from the ground up. You’ll work directly with the CEO, CTO, and most importantly, our customers. Things change regularly, and here are examples of the types of work you’ll be working on:

• Design and implement agentic AI systems that reason about large sets of unstructured data

• Ship full-stack features with direct user feedback

• Contribute to the product…
