Antithesis runs your entire system inside a deterministic simulation, breaks it in every way we can think of, and hands you a root cause with a perfect reproduction — no flaky tests, no false positives, no "works on my machine." Engineering teams debug faster and ship with far more confidence. AI-generated code has made this work more urgent than ever. Agents write code faster than any human can, but faster code isn’t better code if it’s buggy, stuck in review, or quietly failing in production. The verification bottleneck is real, and it’s growing. That is precisely the problem Antithesis exists to solve. We’ve spent years quietly rethinking how the world approaches software reliability, and we’re just getting started. We’re well-funded, deeply technical, and headquartered in Northern Virginia with satellite offices in London and San Francisco. Our team is in the office daily, which is how we take on hard problems together. If that sounds like fun to you, keep reading. ## About the Role Antithesis is looking for an Accounting Operations Manager to build and run the operational backbone of our finance function. You'll own the systems, workflows, and controls that sit underneath our accounting work — making sure close runs smoothly, data is reliable, and the team can scale without adding headcount proportionally. This role is for someone who sees process as leverage. You should be equally comfortable in the weeds of an ERP configuration and presenting a controls framework to leadership. We're in the office daily in Vienna, VA. ## What you'll do - Run accounting side of our scale-up program, including owning the roadmap, sequencing, and delivery of systems and process projects (think intake, scoping, milestones, etc.) - Drive and manage the global expansion of accounting and finance functions, ensuring successful operations during rapid company growth across - Design and document accounting workflows, controls, and policies - Partner with finance, engineering, and ops to source and implement new tools and processes as the business grows - Drive automation across the accounting and finance function, from operations to reporting - Build audit readiness infrastructure - Identify and resolve bottlenecks in how accounting work gets done ## What we're looking for - 5+ years in accounting operations, finance systems, or a accounting-adjacent role - CPA preferred - PMO experience - PMP certified - International experience - including multi-entity and multi-currency configuration - Hands-on experience with ERP administration, ideally NetSuite or Sage Intact - Strong understanding of GAAP and how accounting principles translate into system design - Track record of building processes and controls in a fast-moving environment - Analytically sharp with the ability to think in systems, not just tasks - Comfortable working across technical and non-technical teams - High ownership orientation; you treat the accounting infrastructure as yours to improve ## 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. ## Sources 1.
