Data Engineer (Sports & Prediction Markets)

About Betstamp Ventures

One team. Four high-growth businesses. More than 2 million people using what we build.

Betstamp Ventures spans iGaming technology, market data and odds pricing, trading and market making, and acquisition and media. We price 200+ sportsbooks, operate a portfolio of consumer apps, and run our own media company.

It started with Betstamp, the free odds comparison and bet tracking app that professional bettors built in 2020 because the market didn't offer sharp enough tools. It's earned 200,000+ downloads and a 4.9-star rating, and the pricing behind it now runs across the industry. Today the same team also runs our own iGaming consumer brands and the media and partnerships business that brings players to them, all Canadian-owned and operated from our King Street West HQ in Toronto.

Small by design. One team runs all four businesses, so there's a lot of ground per person, and you're trusted with real scope early.

About Betstamp

This role is on Betstamp, our sports market-data business.

Betstamp is the pricing intelligence layer for sports betting. We turn 200+ sportsbooks, exchanges, and prediction markets into one sharp, real-time view of fair value, for the sportsbooks that price against it, the bettors who bet with it, and the traders who move on it.

We launched in 2020, built by professional bettors who needed sharper tools than the market offered and won at scale using them. That same pricing now runs as infrastructure across the industry. Because it's still used to win real money, it can't drift. Every model is backtested against years of closing lines and monitored continuously. What our customers run on is the pricing we stake our own edge on.

What we build

One pricing engine, delivered three ways:

• Sportsbooks and operators get fair-value pricing on player props, alternates, and ladders, correlation-aware same-game-parlay pricing, and a normalized real-time and historical feed that drops into their existing trading stack.

• Professional bettors get Betstamp PRO, the professional odds screen: True Line pricing across 200+ books and real-time edge detection the moment a market is mispriced.

• Prediction market traders get the raw feed by API: sub-second data on every market we cover, benchmarked against the full spread of books and exchanges.

200+ sportsbooks and operators. 2,500+ markets. Sub-second refresh.

Why now

We're at the point where a product built for bettors has become infrastructure the industry runs on, and prediction markets have opened a category that barely existed three years ago. That's a rare window, and we're small enough that the people who join now shape what gets built rather than maintain what already exists.

The work has unusual clarity to it. Pricing is either sharp or it isn't, and our customers would know within a day if it weren't. You'll see the effect of your work quickly, and you'll be trusted with real scope early.

Who You'll Work With

You'll be part of our engineering team, working every day with the people who build our sports data platform.

The Role

We track odds across sportsbooks, exchanges, and prediction markets in real time, calculating line movement, best available price, edge, and expected value. Our Go monorepo includes sportsbook scrapers, a Redis Streams and ClickHouse data pipeline, and the REST API powering pro.betstamp.com and our props screen. You'll help maintain and improve these systems as feeds change, markets move, and integrations break.

AI is central to how we work. You'll be expected to use coding agents and other AI tools heavily for implementation, debugging, testing, and investigation, while reviewing their output carefully and remaining accountable for the result.

What You'll Own

• Ingestion pipelines: Reliability, coverage, and latency across 100+ scraper integrations, including fixes for feed changes, renamed markets, and blocking.

• Data pipeline and databases: Redis Streams, our market processor, Atlas migrations, and ClickHouse schemas.

• Query performance: Optimize PostgreSQL and ClickHouse for markets, fixtures, and line-history workloads.

• Monitoring: Prometheus and Grafana alerting that catches a degraded feed before a customer does.

• AI-enabled development: Use AI to move faster and automate repetitive data engineering work

You'll begin with scrapers and gradually take ownership across the stack. Architecture decisions, production incidents, and irreversible changes will be handled alongside a senior engineer.

The Stack

Go 1.25

· PostgreSQL 18, Atlas, and ClickHouse

· Redis/Dragonfly, Redis Streams, and RabbitMQ

· Kubernetes, Docker, and GitHub Actions

What We're Looking For

• Strong fundamentals in a backend language such as Go, Java, C#, Rust, C++, Kotlin, or server-side TypeScript

• Comfortable working with SQL and investigating query performance

• Some experience with Linux and containers

• Active, thoughtful use of AI coding tools, with the judgment to verify their work

• An interest in how AI can improve engineering workflows and products

• A habit of verifying assumptions and communicating clearly

• Based in Toronto or willing to relocate

Go experience isn't required, but you should be able to become productive in it within a few weeks.

Nice to Have

• Experience scraping websites or reverse-engineering undocumented APIs

• Experience with ClickHouse, Prometheus, or high-throughput streaming systems

• Experience building internal tools with LLM APIs

• An interest in sports, betting, or prediction markets

What’s In It for You

• Competitive salary & raises: share in the upside you build

• Autonomy & influence: real scope early, not tickets

• Gear & learning stipend, plus free rein testing and spending on the AI tools of the future

• World-class betting tools: the same tools professional bettors pay for, free

• Sports-centric culture: team watch parties, office prop pools, and the inside scoop on sharp bets

The Process

• Short video intro: a few questions, recorded on your own time

• 45-min intro call: meet the team, swap questions

• Lightweight take-home (under 2 hours): a real problem from this codebase, not a LeetCode exercise

• Systems conversation: a real problem together, no whiteboard algorithms

• Final interview: meet leadership

• Offer → onboarding → shipping to thousands of bettors
