## Job description

## ABOUT TOWN

We're an applied AI company building a powerful assistant that makes it easy for anyone to create and use software in their everyday work. Town starts from who you are — it builds a persistent model of you (your voice, judgment, relationships, priorities) and does real work on your behalf across every tool you use: email, calendar, docs, Slack, CRM. It doesn't wait to be prompted. It observes, learns, and acts.

We most recently raised a $55M Series A led by Andreessen Horowitz, with participation from Forerunner Ventures and continued support from First Round Capital, Alt Capital, and Conviction — plus angels including Adam D'Angelo, Soleio Cuervo, and Immad Akhund.

## ABOUT THE ROLE

Town holds the keys to a person's entire working life. To do real work on someone's behalf, it reads their email, moves through their calendar, acts in their docs, Slack, and CRM. This means that security is absolutely paramount. We're looking for a dedicated Security Engineer to own that surface end to end.

You'll set the security bar for a company whose whole premise is trusted, autonomous access to sensitive data. That means securing the product and the agent that acts inside it, hardening the infrastructure and data pipeline behind it, and building the practices - threat modeling, secure SDLC, incident response. etc. that let us move fast without betraying that trust.

## WHAT YOU'LL DO

- Own application and product security across the Town assistant and the agent action surface — the systems that read and act on user data across email, calendar, docs, Slack, and CRM.
- Threat-model autonomous agent behavior: prompt injection, tool misuse, the "lethal trifecta" of untrusted input + sensitive data + external action, and the guardrails that contain it.
- Secure the data pipeline behind Town's persistent model of each user — encryption, tenant isolation, access controls, and secrets management.
- Harden our cloud infrastructure and third-party OAuth integrations (Google, Slack, CRM) against real-world attack.
- Build the secure development lifecycle: design reviews, code review for security, dependency and supply-chain hygiene, and the tooling to scale it.
- Stand up and run incident response — detection, triage, and clean postmortems.
- Partner across engineering to make the secure path the easy path.

YOU MIGHT THRIVE HERE IF YOU...

- Have extensive experience in security engineering, with real depth in application and/or infrastructure security.
- Can read and write production code — you fix problems, not just file them.
- Have secured a multi-tenant SaaS product handling sensitive user data at scale.
- Know your way around cloud security (AWS and/or GCP), authn/authz, secrets, and encryption in practice.
- Threat-model instinctively and can explain risk to engineers and founders without hand-waving.
- Want to be the person who owns security from the ground up, and move at startup speed doing it.
- Get energy from working in person - we're 5x per week at our office in downtown SF

## LOCATION

In-person in San Francisco's Financial District, five days a week. Everyone is here to do their best work and make this product a success.

## About Town.com, Inc.

## Company Overview
- **One-liner**: An applied AI company building a proactive, persistent AI assistant that learns how you work and acts on your behalf across email, calendar, docs, Slack, and CRM.
- **Entity Type**: Private (Series A)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2024
- **Founders**: Jean-Denis Greze (CEO, former CTO of Plaid) and Tony Vincent (CPO, former Director of Applied AI at Google)

## Core Business
- **Primary industries**: Artificial Intelligence, Enterprise Software, Productivity
- **Target customers**: B2B (SMB to mid-market teams looking to automate knowledge work)
- **Mission**: "Make it easy for anyone to create and use software in their everyday work." — Town careers page

## Products & Services
- **[Town AI]**: A SaaS assistant that builds a persistent model of a user’s voice, judgment, relationships, and priorities. It observes, learns, and acts without waiting for prompts — triaging inbox, managing schedules, running workflows, and generating drafts. Replaces general-purpose chatbots like ChatGPT and Claude for daily work.

## Market Standing
- **Valuation**: Not publicly disclosed
- **Key Metric**: Total funding of **$73M** (Seed $18M + Series A $55M) — some sources report $78.1M, likely including a smaller prior round or adjusted amount.
- **Notable Investors/Partners**: Series A led by **Andreessen Horowitz** with participation from **Forerunner Ventures**, **First Round Capital**, **Alt Capital**, and **Conviction**. Seed led by **First Round Capital**. Angel investors include Adam D’Angelo, Soleio Cuervo, and Immad Akhund.
- **Growth Signals**: Headcount grew **82.4% year-over-year** (LinkedIn, 2026). Currently **13–31 employees** depending on source. Early customers report replacing Claude, ChatGPT, and “OpenClaw” with Town because it “actually understands them.” The company was founded in 2024 and closed a $55M Series A in May 2026, signaling strong investor confidence.

## Competitive Advantages
- **Proactive persistence**: Town builds a model of the user’s preferences and takes action without explicit prompting — a deeper “memory” than chat-only AIs.
- **Deep tool integration**: Connects to email, calendar, Slack, CRM, and docs, acting across all of them.
- **Founder pedigree**: CEO scaled Plaid from $10M to $300M+ ARR; CPO co-founded a company acquired by Google and another by Dropbox.
- **Early traction**: Customers report preferring Town over leading competitors for daily work.

## Strategic Focus
- Aggressively building out the product and team in 2026 (5 open roles across engineering, product, design, business operations, and marketing).
- Scaling from early adopters to a broader SMB/mid-market audience.
- Continuing to iterate on the “persistent AI assistant” paradigm.

## Why Work Here
- **Culture**: “Action first. Chat second.” Principles include owning outcomes, making decisions with 70% information, and debating hard with ego aside.
- **Work environment**: Fully in‑person, five days a week in San Francisco’s Financial District. Early‑stage (one of first ~20 teammates) means high impact and ownership.
- **Compensation**: AI Product Engineer $225K–$300K, Staff Backend Engineer $250K–$300K, Business Operations $130K–$170K, Product Marketing $150K–$200K — all with competitive equity.
- **Benefits**: Fully covered medical, dental & vision; unlimited PTO; free daily lunch; commuter benefits; parental leave; 401(k).
- **Team**: Engineers and operators from Plaid, Apple, Facebook, Stripe, Lyft, Dropbox, CrowdStrike, HubSpot, Quora, and Asana.
