## Job description

## About F2

F2 is redefining how the financial sector operates by bridging the gap between legacy workflows in institutional finance and the future of AI-driven efficiency. While large financial firms comprise the backbone of the economy, their front and middle-office processes are still manual, spreadsheet-heavy, and fragmented.

F2 is the leading vertical AI platform purpose-built for private markets and commercial banking. We transform dense, unstructured deal materials into auditable, decision-ready insights in minutes. This is not generic AI tooling. It is core infrastructure embedded directly into underwriting, credit, and portfolio workflows. We are the only fully vertical platform in this space with meaningful, proven revenue and real product–market fit.

## The Role

We are seeking a hands-on Senior Software Engineer who loves building from 0→1 and shipping product that customers feel. You will actively write production code and deliver critical platform components from scratch, working closely with the team to power F2's AI-driven platform, helping private markets investors analyze deals with velocity and accuracy.

What you'll do:

- Build our product. Own and implement software features end-to-end across the stack that power our AI platform. In this role you are actively coding and delivering critical platform components from scratch, not just planning them.
- Deliver excellence and quality. Set and uphold coding standards, architectural patterns, and review processes; mentor engineers. Co-own a culture of practical, reliable, test-driven development that rapidly addresses real business needs.
- Build for scale. Contribute to monitoring, scaling, and hardening the architecture of the platform and the systems behind it as enterprise demand grows.
- Cross-functional collaboration. Partner closely with product, security, and go-to-market teams to translate our roadmap into features and deliverables that ship quickly and hold up in production.

What you bring:

- Full-stack experience. 4+ years building production software across frontend and backend, with a track record of shipping features end-to-end.
- Passion for engineering and learning. You care about your craft and continuously push to get better.
- AI fluency. Comfort building with AI at the core — integrating LLMs, retrieval, or agents into real product experiences.
- Modern web expertise. Strong grasp of modern web application development practices and patterns.
- Bonus points. Familiarity with Python, FastAPI, TypeScript, Node.js, Supabase, and AWS is a plus.

Location: San Francisco Employment Type: Full time Location Type: Hybrid Department: Engineering, Product, Design (EPD) Compensation: $175K – $225K • Offers Equity The total rewards package at F2 includes base salary, equity (stock options), and benefits.

## About F2

## Company Overview
- **One-liner**: F2 is an AI platform purpose-built for private markets investors — it helps private credit, private equity, and commercial banking teams screen, diligence, underwrite, and monitor deals faster and with greater institutional knowledge.
- **Entity Type**: Private (Seed stage; raised $10.1M total)
- **Headquarters**: New York, NY, United States
- **Founded**: 2025
- **Founders**: Don Muir (Co-Founder & CEO), Emre Kazdagli (Co-Founder & CTO)

## Core Business
- **Primary industries**: Financial technology (Fintech), AI for private markets (private credit, private equity, commercial banking)
- **Target customers**: Investment firms, asset managers, commercial banks – B2B Enterprise
- **Mission or purpose**: “Turn every transaction into a proprietary advantage that makes the firm smarter over time” – compounding intelligence for private markets.

## Products & Services
- **F2 Platform (Institutional Knowledge)**: A unified SaaS platform that ingests a firm’s historical IC memos, financial models, CIMs, and CRM data into a queryable “living library.” Teams can pull precedents, surface past risks, and underwrite with the pattern recognition of the most experienced deal leads. Includes:
  - **Screening & Diligence**: Context-aware search across all past deals and market data.
  - **Underwriting (Excel-Native Engine)**: A real Excel engine underneath the AI that outputs live Excel files with formulas, cell references, and dependency tracking. No black boxes.
  - **Audit Mode**: Click any number to see the formula and trace it back to its source cell.
  - **Portfolio Monitoring**: Covenant performance, exposure testing, and fund-level reporting.
- **Additional Features**: Downside risk & covenant analysis, sponsor & stakeholder analysis, cash flow & coverage metrics, precedent comp tables.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of **$10.125M** (Seed rounds in 2025; includes a $10M round led by NFX, Left Lane Capital, and Y Combinator)
- **Notable Investors/Partners**: NFX, Left Lane Capital, Y Combinator
- **Growth Signals**:
  - Over **15,000 deals** underwritten annually on F2 across firms managing more than **$400B in client assets**.
  - #1 on **SpreadsheetBench**, the industry standard benchmark for spreadsheet AI.
  - SOC 2 Type 1 & Type 2 certified, GDPR compliant.
  - Team grew to ~20 employees within first year (monthly headcount growth +4.3% as of mid-2026).
  - Active hiring for multiple roles (10 open positions as of July 2026).

## Competitive Advantages
- **Excel-Native AI**: Unlike general-purpose AI, F2 runs a real Excel engine – outputs are genuine .xlsx files with live formulas, dependency tracking, and transparent audit trails.
- **Institutional Knowledge Compounding**: Every deal that passes or closes automatically flows back into the library, so the platform gets smarter with each transaction.
- **Enterprise Security & Trust**: Zero data retention, no model training on customer data, SOC 2 Type II, role-based access, GDPR compliant.
- **Specialized for Private Markets**: Built specifically for the workflows of private credit and private equity, not a horizontal AI tool.

## Strategic Focus
- Scale adoption among institutional investors (private credit, commercial banking, PE).
- Deepen the platform’s institutional knowledge capabilities and grow the dataset from customer deals.
- Continue to invest in financial accuracy and spreadsheet-native AI (maintain #1 position on SpreadsheetBench).
- Expand the team across engineering, sales, and client success.

## Why Work Here
- **Early-stage impact**: As a YC S25 company with 15–20 employees, new hires will have significant ownership and influence on product and culture.
- **Hybrid / Remote**: The company is headquartered in New York City with a hybrid model; many roles are listed as hybrid or remote (some fully remote). Employees work remotely across the U.S.
- **Culture highlights**: Fast-paced, mission-driven environment focused on solving a real pain point in finance. “Force multiplier” ethos – giving analysts the pattern recognition of experienced managing directors.
- **Engineering culture**: Emphasis on architectural rigor (real Excel engine, AI accuracy), with roles for senior software engineers (frontend, infrastructure) and AI deployment strategists.
- **Perks**: Not explicitly detailed, but typical YC-backed startup benefits likely include equity, flexible PTO, and a strong focus on professional growth.
