## Job description

## About Antithesis

We’re on a mission to redefine how modern distributed systems are tested and released. Our platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility. Our platform doesn’t just assure system correctness and reliability, it exists because developers need something better. If you’ve ever experienced the pain of a production outage, had a bad week on-call, or had a release delayed by weeks because of one killer bug – you’ll understand exactly why we’re doing what we do. If you're passionate about developer-first products, system resilience, and correctness, we’d love to talk.

## About the Role

We are looking for a "player-coach" who can translate their experience and skillset to amplify a highly capable, fast-growing team. We are looking for candidates who are not only comfortable doing 1-on-1s with team members but able to lead by example with their technical execution and presales skills.

You will be leading a team based in our UK HQ2 office, combined with additional team members based in the APAC region. You will be responsible for maintaining critical business KPIs such as POC conversion rate and presales support volume for customers in the corresponding geographical region.

## What You Do

- Manage the day-to-day operations of the team: onboarding, check-ins, performance reviews, vacation approvals, project (POC) assignments, and more.
- Partner with our corporate recruiters and drive our recruiting effort for the EMEA/APAC region, and participate in the recruiting effort for other GTM functions.
- Collaborate with regional sales leadership on presales support and POC execution.
- Collaborate with global GTM functions such as marketing efforts (conferences) and enablement (training, workshops).
- Help the team up-level their technical and communication skills.
- Be a backstop for team members on customer engagements.

## Who You Are

- You maintain a strong technical foundation from previous related roles and industries.
- You have a strong desire to mentor other team members and feel incredibly rewarded by the success of others.
- You lead from the front, always taking the toughest challenges instead of delegating them to a team member.
- You want to be "hands-on-keyboard" with POC execution and other technical activities.
- You have experience working with Account Executives, sales leaders, and other GTM functions.
- You retain technical curiosity and a willingness to learn new things and absorb new technologies.
- You are comfortable working in tight timelines and high-pressure situations.
- You are a great communicator, both written and verbal.
- You are a good team player, able to work with a small but highly skilled team.
- You are professional but flexible — you can roll with the fast pace of a startup.

Good Skills and Experience to Have

- Software testing, reliability, and distributed systems
- Containerization: Docker, Kubernetes
- Object-oriented programming
- Scripting languages (bash/shell, Python, JavaScript)
- Querying data (via SQL, NoSQL, or other query engines)

This role will require some travel (client site, conferences, Antithesis HQ).

## About Antithesis

## Company Overview
- **One-liner**: Antithesis provides an autonomous software testing platform that uses deterministic simulation and state space exploration to exhaustively find and reproduce bugs in complex, distributed systems.
- **Entity Type**: Private (Series A)
- **Headquarters**: Vienna, Virginia, United States (with satellite offices in London, UK and San Francisco, California)
- **Founded**: 2018
- **Founders**: Will (CEO), Ben (CTO), and Dave (co-founder) – full last names not publicly disclosed

## Core Business
- **Primary industry/industries**: Software testing, autonomous reliability, developer tools, infrastructure software
- **Target customers**: B2B, Enterprise – companies building complex distributed systems (e.g., databases, cloud infrastructure, fintech, blockchain)
- **Mission or purpose statement**: “De‑risk agentic development of critical systems” by exposing bugs without human review, false positives, or risking production.

## Products & Services
- **Antithesis Platform**: A SaaS/on‑prem platform that runs a customer’s complete system in a fully deterministic, ephemeral simulation. It exhaustively analyzes behavior using fuzzing and state space exploration, automatically exposes bugs, provides a root cause and perfect reproduction, and arms developers (including AI agents) with high‑signal correctness feedback.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding – $182 M (latest round: $105 M Series A announced December 3, 2025)
- **Notable Investors/Partners**: Amplify Partners, Spark Capital, Tamarack Global, Patrick Collison, Sholto Douglas, and 31+ other investors. Customers include Jane Street, MongoDB, Confluent, and Tigris Data.
- **Growth Signals**: Launched out of stealth in 2024; 19 open job openings as of mid‑2026; customers report 40 × faster change verification, 10 × faster time‑to‑release, and discovery of severe bugs missed by all other testing.

## Competitive Advantages
- **Deterministic replay** of every bug found – eliminates the “cannot reproduce” problem.
- **Exhaustive state space exploration** that catches unknown unknowns without false positives.
- **Runs the entire system** (not unit/integration tests) – simulates production‑like conditions.
- **Already trusted by elite engineering teams** (e.g., quantitative trading firm Jane Street, leading database companies) – a strong reference moat.

## Strategic Focus
- Accelerate product innovation and expand support for **agentic development** – help AI agents build bug‑free code by providing high‑signal correctness feedback.
- Broaden platform coverage across **databases, cloud infrastructure, fintech, blockchain**, and other critical system domains.
- Scale go‑to‑market and customer success teams to meet enterprise demand.

## Why Work Here
- **Culture**: “Collaborative, highly technical, and customer‑focused” – deep‑tech environment solving hard distributed‑systems problems.
- **Work policy**: In‑office daily (Vienna, London, or San Francisco) to facilitate tackling difficult challenges together.
- **Perks & engineering culture**: Well‑funded startup with a long‑term mindset; team includes veterans from FoundationDB, Apple, Google, and MongoDB; emphasis on autonomy, technical excellence, and fun.
- **Interview process**: Transparent and respectful – they publish a “No Ghost Policy” and welcome unsolicited applications from talented candidates.
