Job description
The role
Y Combinator is looking for a full-stack product engineer who also wants to apply their skills to investing, diligence, and founder support.
This role sits at the intersection of engineering, product, and investing. You will spend much of your time writing production code — building internal and founder-facing tools — while also contributing directly to company evaluation and investment decisions.
This is not two jobs stitched together. The core of the role is turning judgment into software: using code to improve how YC evaluates companies, supports founders, and scales its impact after the batch.
What you'll do
Product & engineering (core responsibility)
Design, build, and ship full-stack web applications for partners, founders, and investors
Own features end-to-end: scoping, design, implementation, and iteration
Work across frontend, backend, and data layers to improve YC's post-batch and internal platforms (e.g. founder tools, analytics, workflow systems)
Make pragmatic engineering tradeoffs in a fast-moving, high-ownership environment
Investing & analysis
Evaluate post-batch and growth-stage companies by analyzing business models, markets, teams, and operating metrics
Contribute to diligence efforts, including reviewing decks and data rooms, benchmarking KPIs, and conducting market or customer research
Build and maintain analytical tools, dashboards, or workflows that support investment decisions
Write clear, structured memos and analyses for partners and investment committee
Who this role is for
This role is ideal for someone who:
Is a strong full-stack engineer and enjoys owning production software
Likes talking to users and senior stakeholders to decide what to build
Is curious about investing and wants hands-on exposure
Prefers ownership and impact over narrowly scoped tickets
Is energized by ambiguity and comfortable making tradeoffs
Can translate ambiguous questions into concrete products, systems, or analyses
Successful candidates have been:
Former founders or early-stage engineers
Product-minded engineers who've worked closely with business or finance teams
Engineers with prior exposure to investing, finance, or company analysis
What we're looking for
Required
Experience shipping full-stack web applications
Ability to design systems and reason about tradeoffs independently
Strong analytical thinking; comfort with metrics and financial concepts
Clear written and verbal communication
Excellent judgment, integrity, and ability to work with sensitive information
Not required, but helpful
Experience with Rails, React, Postgres, or similar frameworks and databases
Prior experience in venture capital, growth equity, banking, consulting, or corporate development
Founder or early-stage startup experience
Experience building internal tools, analytics platforms, or workflow software
We care far more about your ability to build and ship real software than about any specific framework. If you've built strong full-stack products before, you can learn our stack.
How we work
YC operates with a small, high-trust team. Roadmaps evolve organically, priorities shift quickly, and people are expected to use good judgment rather than wait for perfect specs. Engineers have real autonomy and work closely with partners and founders to build things that matter.
Location & benefits
Based in the San Francisco Bay Area (or willing to relocate)
Competitive compensation and benefits
Opportunity for carry in the YC fund
Medical, dental, vision, 401(k), parental leave, and flexible PTO
Important note
This role is not a fit if you're looking for:
A pure investing or finance role with little hands-on building
A pure engineering role with tightly defined specs and limited product ownership
A highly structured environment with rigid roadmaps
