About this job

<p style="text-align:justify;"><strong><span style="color:#000000">Who are we?</span></strong></p><p style="text-align:justify;"><span style="color:#000000">Gain is the Private Markets Super App, a connected global platform transforming how leading investors, advisors, and corporates source, evaluate, and execute deals. By combining investment-grade intelligence, AI-powered workflows, and proprietary data in one unified platform, Gain enables top deal teams to move faster, reduce risk, and build conviction with confidence.</span></p><p style="text-align:justify;"><span style="color:#000000">Gain is trusted across more than $1 trillion of private capital, used by 100% of MBB and Big Four firms, and by 80% of the world’s top 20 M&amp;A advisory houses.</span></p><p style="text-align:justify;"><span style="color:#000000">Recognized for fast innovation and impact, Gain has been named both US and EU Data Provider of the Year by PE Wire, awarded Global Financial Market Review’s Best Use of AI in Finance, and ranked in Sifted’s Top 100 Fastest-Growing Companies, the Forbes 1000, and the Deloitte Technology Fast 50. Gain operates globally with offices in New York, London, Amsterdam, Frankfurt, Warsaw, and Bangalore.</span></p> <br> <p><strong><span style="color:#000000">How we work</span></strong></p><ul><li><p><strong><span style="color:#121317">Predicting what isn't published.</span></strong><span style="color:#121317"> Many private companies publish little or no financial detail. Across a database of more than 5 million companies, we predict revenue and EBITDA from sparse labels, and we predict whether and when a company will be bought or sold, which is a time-to-event problem with censored data.</span></p></li><li><p><strong><span style="color:#121317">Agents on a messy web.</span></strong><span style="color:#121317"> Our agents search, navigate and extract company data points from sources that contradict each other, then decide which source to trust before committing to an answer.</span></p></li><li><p><strong><span style="color:#121317">Quality that holds while everything underneath moves.</span></strong><span style="color:#121317"> We're provider-agnostic. Model choices follow the evals, and we switch LLMs when the numbers say so. That only works if the evals are trusted.</span></p><p style="min-height: 1.7em;"></p></li></ul><p style="text-align:justify;"><strong><span style="color:#000000">What will you do?</span></strong></p><p><span style="color:#121317">The work is roughly half LLM agents and half custom ML, leaning slightly toward agents.</span></p><ul><li><p><span style="color:#121317">The design of our agent pipelines: architecture, tools, and which model for which task. You'll shape the technical direction with our AI Lead.</span></p></li><li><p><span style="color:#121317">The evaluation behind agents and models: offline reference sets, live production evals, and the call on whether an improvement is real.</span></p></li><li><p><span style="color:#121317">Our prediction models for financials and deals: features, validation, retraining, and knowing when a simpler model wins.</span></p></li><li><p><span style="color:#121317">Getting work into production: trace where pipelines fail and fix the weakest links first, with compute, memory and model cost in view.</span></p></li><li><p><span style="color:#121317">Raising the bar in the team through design reviews, pairing, and an eval-first habit that sticks.</span></p></li></ul><p style="min-height: 1.7em;"></p><p><span style="color:#121317">In your first six months you'll own the evals for our agent pipelines, propose where we invest next, and ship measurable improvements to both the agents and the prediction models.</span></p><p style="text-align:justify;min-height: 1.7em;"></p><p style="text-align:justify;"><strong><span style="color:#000000">Who are you?</span></strong></p><ul><li><p><span style="color:#121317">You've built and owned ML systems in production for years, typically 6+ in ML or software engineering.</span></p></li><li><p><span style="color:#121317">In the last 1–2 years you've shipped LLM agents or pipelines that real users depend on, not demos.</span></p></li><li><p><span style="color:#121317">You have modelling judgement. You've dealt with leakage, distribution shift and calibration on real data.</span></p></li><li><p><span style="color:#121317">You measure before you claim. You can build an evaluation set and tell an honest improvement from a lucky one.</span></p></li><li><p><span style="color:#121317">You care about the user outcome more than the technique. Ideas without a clear customer benefit don't get built here, however interesting.</span></p></li><li><p><span style="color:#121317">Nice to have: time-to-event modelling, noisy or conflicting data sources, financial or private-company data. No finance background needed.</span></p></li></ul><p style="min-height: 1.7em;"></p><p><strong><span style="color:#121317">The team</span></strong></p><p><span style="color:#121317">You'll join our Data &amp; AI team of six and report to Renan, our AI Lead who's been building production models for &gt;10 years. Our engineering team runs the infrastructure, and you shape what runs on it.</span><br></p><p style="min-height: 1.7em;"></p><p><strong><span style="color:#000000">The stack</span></strong></p><ul><li><p><strong><span style="color:#000000">Core:</span></strong><span style="color:#000000"> Python (async, fully typed with Pydantic) and FastAPI</span></p></li><li><p><strong><span style="color:#000000">LLMs:</span></strong><span style="color:#000000"> multiple providers behind our own provider-agnostic layer, with Pydantic AI for typed agents. </span></p></li><li><p><strong><span style="color:#000000">Evals and observability:</span></strong><span style="color:#000000"> Pydantic Evals and Logfire</span></p></li><li><p><strong><span style="color:#121317">Data:</span></strong><span style="color:#121317"> PostgreSQL with pgvector</span></p></li><li><p><strong><span style="color:#000000">Cloud:</span></strong><span style="color:#000000"> GCP (Cloud Run, Cloud Tasks), Docker, GitHub Actions</span></p></li></ul><p style="min-height: 1.7em;"></p><p><strong><span style="color:#000000">What do we offer?</span></strong></p><ul><li><p><span style="color:#000000">Competitive </span><strong><span style="color:#000000">base salary</span></strong><span style="color:#000000"> and </span><strong><span style="color:#000000">annual bonus</span></strong><span style="color:#000000"> linked to your performance / OKRs</span></p></li><li><p><span style="color:#000000">Attractive benefits including health &amp; wellbeing allowance, work-from-home budget, learning &amp; coaching benefits, etc.&nbsp;</span></p></li><li><p><span style="color:#000000">Flexible hybrid working model with 3 days per week in our Amsterdam office&nbsp;</span></p></li><li><p><span style="color:#000000">Healthy work-life balance allowing for planability and personal commitments&nbsp;</span></p></li><li><p><span style="color:#000000">Chance to grow with the company gaining increasing responsibilities, supported by lots of coaching and a feedback-driven approach&nbsp;</span></p></li><li><p><span style="color:#000000">Tremendous learning and career progression opportunities&nbsp;</span></p></li><li><p><span style="color:#000000">International environment with hubs in New York, London, Amsterdam, Frankfurt, Warsaw, and Bangalore</span></p></li><li><p><span style="color:#000000">Culture of trust, ownership and standard of excellence and a fun working atmosphere with regular outings and events&nbsp;</span></p></li><li><p><span style="color:#000000">Post product-market fit and aspiring unicorn status - this is an excellent time to join &amp; grow with us!</span></p></li></ul><p style="min-height: 1.7em;"></p><p style="text-align:justify;"><strong><span style="color:#000000">Does this sound like a perfect match?</span></strong></p><p style="text-align:justify;"><span style="color:#000000">We are proud of our wonderful product and believe it has lots of potential.
