## Job description

## Role

At Variance, we are teaching machines to make the hardest judgement calls at scale. That means building AI agents for the high-precision gray-area of risk investigations, fraud, and identity reviews.

We’re a small, talent-dense team in San Francisco, tackling problems that touch billions of events and entities. Our customers include several Fortune 500s, global marketplaces, and regulated financial services.

- Have 1-3 years of experience of professional software engineering experience
- Care deeply about craftsmanship and have strong opinions about building high-quality products

- Enjoy owning features end-to-end, from backend systems to polished UI to production
- Thrive in fast-moving environments with short iteration cycles and a high degree of responsibility
- Are excited by the prospect of building AI interfaces for high-stakes decisions that protect people from fraud, scams, and abuse

## What you’ll do

- Build and ship features end-to-end with iteration cycles measured in hours, not quarters
- Work across the stack to turn ambiguous problems into reliable product experiences
- Partner directly with the founders on massive-scale, frontier problems
- Scale our product into new industries and workflows through fast pilots and live demos
- Design systems where AI must decide in real time, balancing precision, speed, and user trust
- Help improve the product through rapid feedback, experimentation, and strong execution

Our culture We believe in ownership, urgency, and craft. We enjoy spirited debate, wild ideas, and building things we’re proud of. We’re fully in-person in San Francisco.

## About Variance

## Company Overview

- **Entity Type**: Private (Series A, $21.5M raised in March 2026)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2022
- **Founders**: Michael Lin and Karine Mellata

## Products & Services
- **Variance AI Agents**: A suite of AI agents designed to automate the full investigative workflow for compliance and risk teams. Agents can handle tasks from Level 1 to Level 3 reviews, including sanctions screening, fraud review, and identity verification. They extract insights from messy data (scanned documents, images, websites) and provide a complete, auditable evidence trail for every decision. [variance.com](https://www.variance.com/)

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed.
- **Key Metric**: Total Funding of $24.6M ($3.1M Seed in 2024 + $21.5M Series A in March 2026). [ycombinator.com](https://www.ycombinator.com/companies/variance)
- **Notable Investors/Partners**: Y Combinator (Winter 2023 batch), with the Series A led by a prominent venture firm (specific lead investor not named in the provided search results, but the round was reported by Axios and Business Wire).

## Competitive Advantages
- **Auditability & Explainability**: Unlike many "black box" AI systems, Variance is "built for regulators and auditors." Every decision comes with a complete, cited evidence trail, making it defensible in a highly regulated environment.
- **Adversarial Focus**: The company is explicitly designed for "highly adversarial environments" where threats evolve constantly, giving it a sharper focus than general-purpose automation tools.
- **Speed to Production**: The company emphasizes a culture of velocity, measuring timelines from prototype to production in "days, not months," allowing them to adapt quickly to new fraud patterns.

## Strategic Focus
- **Deepening Enterprise Sales**: The company is actively hiring Enterprise Account Executives and Sales Engineers, indicating a push to expand its customer base among large, regulated institutions.
- **Product Development**: Open roles for Research Engineers (Evals, Judgment Systems) and Senior Software Engineers suggest a continued focus on improving the accuracy, reliability, and reasoning capabilities of their AI agents.
- **Scaling the Team**: With a Series A close in early 2026, the company is in a clear growth phase, expanding its engineering and go-to-market teams from a small base (12-person team per YC profile).

## Why Work Here
- **Culture & Values**: The company emphasizes a culture of **Ownership** (every employee is an owner from day one), **Velocity** (fast iteration), **Craftsmanship** (deep care and intentionality in building), and **Impact** (building systems trusted for mission-critical decisions). [variance.com](https://www.variance.com/company)
- **Work Policy**: In-person in San Francisco.
- **Compensation & Perks**: Offers competitive salary and meaningful equity. Benefits include platinum-tier medical/dental/vision insurance, a 401(k) program, unlimited PTO/sick leave/parental leave, daily catered lunches and dinners, a monthly wellness stipend, commuter benefits, and company events. [variance.com](https://www.variance.com/careers)
- **Engineering Culture**: A high-agency environment where engineers own end-to-end responsibility for systems. The work is technically challenging, involving building AI that operates in real-time against sophisticated adversaries.
