Build the second line.

Own the voice. Second Line sells a disciplined read on live games to people who bet them, and the voice has to earn trust in a category built on hype. You run every word members and prospects see: the site, the pick copy, the game-day content, the public record narrative, video and social. You report to the founder.

• Set and enforce the editorial standard: plain, quantitative, never a lock, never a guarantee, losers counted.
• Build the game-day content engine: live-game threads, post-game receipts, weekly ledger reviews, the newsletter.
• Turn the research into content people can follow without giving away the method: what a grade means, why PASS is an answer, why one position per market.
• Run video and social from zero: formats, cadence, hosts, and the numbers behind them.
• Own the how-it-works surface with product and engineering, and the source notes behind every grade.
• Hire and manage writers, editors and producers as the audience grows.

• Ten or more years in sports media, betting content or financial media, with at least three running a team.
• You have written for bettors and know the difference between a pick and a claim.
• Fluent in the numbers: hit rate, return per position, break-even at −110, confidence intervals. You will not publish a figure you cannot defend.
• Comfortable with compliance: 21+, responsible gambling, state-by-state wagering law, and what a tout is not allowed to say.
• You can produce a live-game thread at 1 p.m. on a Sunday and edit a 4,000-word explainer on Tuesday.

• Sportsbook, DFS or betting-media background.
• On-camera experience.

Equity potential of 0.5% – 2%, vesting over four years with a one-year cliff. Salary is discussed individually with each applicant and is not published. Remote, with availability on NFL game days.

Take a paid product with a public record to its first ten thousand members, without a single word we would regret. You own growth: acquisition, partnerships with media and creators, affiliate and referral programs, lifecycle, pricing tests, and the relationships with the operators and data providers our members use. You report to the founder.

• Build the acquisition engine: creator and affiliate partnerships, paid where it pays back, referral, lifecycle email and SMS.
• Negotiate and manage partnerships with sports media, podcasts, betting communities and tools.
• Own retention: onboarding, the first game day, the first losing week, the annual upgrade.
• Run pricing and packaging experiments across Member and Desk with product.
• Stand up analytics for the funnel and report it weekly with the same honesty the record page uses.
• Keep every campaign inside the language rules: no locks, no guarantees, no compounding projections.

Join as one of the first engineers with a founder's stake in the outcome. The engine already prices every NFL game live, publishes a timestamped ledger, and delivers picks to members; the next two seasons are about scale, latency, new sports and the member experience during a game. You will own large parts of the system end to end and help shape how the team is built.

• Own the live pipeline: collection, pricing, alerting and delivery from kickoff to final, at 15-second resolution.
• Design the path from one sport to four without rewriting the engine.
• Build the member experience during a game: the desk, delivery, fills, updates, the ledger.
• Set engineering practice: tests against fixtures, walk-forward validation, append-only records, reproducible research.
• Interview and hire the engineers who come after you.

• Seven or more years building production systems, with at least one thing you built that had to work at a specific minute.
• Fluent in Python and TypeScript; comfortable with pandas, a message pipeline, AWS, and a modern React stack.
• You have shipped data products where being wrong costs money, and you know how to check.
• You want ownership more than a title, and you can work with a founder who reads the code.

• Sports data, market data or trading-systems background.
• Experience with Next.js on Vercel, DynamoDB, Stripe.

Equity potential of 1% – 2%, vesting over four years with a one-year cliff. Salary is discussed individually with each applicant and is not published. Remote, with availability on NFL game days.

The edge is latency. You own the stack that gets a decision from a live game state to a member's phone inside a minute, and the measurement that proves it did: collection, pricing, event triggers, delivery, and the obtainability record.

• Own the live collectors, the pick monitor and the delivery job: uptime, latency, credits, failure modes.
• Measure end-to-end latency and fill quality per pick and per book, and drive them down.
• Build the streaming path from the engine to the desk (SSE or WebSocket) and the update history per position.
• Harden the box: supervision, alarms, deploys, recovery from a lost slate.
• Extend the pipeline to the next sport with the same guarantees.

• Five or more years in backend or infrastructure engineering with real on-call experience.
• Python, Linux, Docker, AWS; comfortable reading a pandas pipeline and a supervisor script.
• You measure before you tune and you write the test that would have caught the last outage.

• Odds feeds, exchange or trading infrastructure.
• Go or Rust for the hot path.

You own what members touch: the desk during a game on a phone, the ledger, the performance page, onboarding and billing. Dense, fast, calm; a pick has to be readable with one thumb while a game is on.

• Own the Next.js app: the desk, game detail, inbox, ledger, account, sign-up and checkout.
• Build the mobile desk: bottom navigation, the fill-logging sheet, per-position updates, push.
• Keep the marketing site honest and fast: the story, the evidence, the record.
• Instrument what members do during games and turn it into product decisions.
• Own accessibility, performance budgets and reduced-motion paths.

• Five or more years in front-end or full-stack engineering; expert in React and TypeScript, strong in CSS.

Extend the research that the product is built on. We have four seasons of in-play prices, twenty-five seasons of play-by-play, a catalog of several hundred documented experiments, and a discipline: pre-stated kill criteria, controls that must reproduce a published number, walk-forward by season, real posted prices. You add to it, and you retract when the data says so.

• Run the research queue: new triggers, new markets, new sports, calibration, capacity and obtainability.
• Build and grade challengers in shadow against the live champion.
• Own the backtest artefacts and the evidence sentences behind every grade.
• Write the doc for every result, negative ones included.

• Graduate-level statistics or equivalent, and three or more years applying it to markets, sports or forecasting.

Keep an analytics company that talks to bettors on the right side of every line. State wagering law, advertising rules, responsible-gaming standards, affiliate disclosures, privacy, and the terms we sign with operators and members.

• Map state-by-state exposure for an analytics product and keep it current.
• Build the responsible-gaming program: limits, self-exclusion pointers, messaging.

• Onboard new members: books, sizing, alert rules, the first game day.
• Write the help center and keep the how-to-read-a-pick page true to the product.
