Lead Architect, Finance Technology

Seatgeek

SEATGEEK BELIEVES LIVE EVENTS ARE POWERFUL EXPERIENCES THAT UNITE HUMANS. WITH OUR TECHNOLOGICAL SAVVY AND FAN-FIRST ATTITUDE WE’RE SIMPLIFYING AND MODERNIZING THE TICKETING INDUSTRY. The Financial Technology team builds the systems SeatGeek's finance org runs on, and we're in the middle of an ambitious push to fundamentally change how accounting gets done. We're transforming how the entire controller organization operates - accounting, AP, tax, reconciliations, accruals - taking the routine, manual work and handing it to specialized AI agents and automations, so our team can spend their time on judgment instead of toil. This is a role for someone who knows enough finance to be dangerous and is relentless about automating it. As Lead Architect, you'll hit the ground running on an ambitious backlog of automation work, burn through it, and then take it further - raising the bar for what's possible and transforming how the work itself gets done. More building, more agentic development, less pointing and clicking. You don't need to be a career software engineer; you'll partner with a strong Finance Technology engineering team on the heaviest builds. What we need is someone who understands the domain deeply enough to see what should be automated, is endlessly curious about how to build it, and learns fast enough to go do it. WHAT YOU'LL DO * Execute against a well-defined automation roadmap and accelerate it - then push it to the next level, both in what we automate and in how we build it * Change how the work gets built - move us toward CLI-driven and agentic development and away from manual, point-and-click configuration, raising the technical bar for the whole team along the way * Build automations and AI agents across accounting, AP, tax, and the close - from inbox triage and invoice coding through reconciliations, flux analysis, accruals, and tax workflows * Help implement our close-management tooling (e.g. Ledge), including its NetSuite and data warehouse connections and the reliability work that makes an agentic close trustworthy * Configure and extend NetSuite, Zip, and the integration layer that ties our finance systems together, making sound calls on where logic should live across ERP, integration layer, and code * Work directly with accountants to understand their workflows, translate that into automation, and earn their trust in the systems you put in front of them * Make build-or-buy decisions and work with technology vendors, constantly weighing what to build in-house against what to bring in * Raise the bar for this work through design reviews, monitoring, and pragmatic operational practices - especially around the reliability and auditability that financial systems demand * Raise the bar for everyone around you - through how you build, code, design reviews and helping interview and grow the people on the team WHAT YOU HAVE * 5+ years of experience * Dangerous on accounting without being a career accountant - you understand how a controllership runs (accounting, AP, tax, the close) and can spot where the toil is and how to kill it * Intensely dissatisfied with the status quo - manual, repetitive process genuinely bothers you, and you can't leave it alone. You're the person who automates their own work, then comes for everyone else's * A fast and fearless learner - you move into unfamiliar tools, systems, and problems quickly and come out the other side dangerous * Relentless automation and AI curiosity - you stay on top of what AI can do, you've built or experimented with agents and automations yourself, and you have opinions about where it's genuinely useful * A roll-up-your-sleeves builder's instinct - you'll dig into system config, integration tools, scripting, and agent-building yourself, teaching yourself the parts you weren't trained for rather than waiting for someone else * Ambitious and opinionated - you bring a strong point of view, push for the better solution, and aren't satisfied with how things are done today * You're comfortable operating without a playbook - defining the approach, the architecture, and the roadmap simultaneously * You're able to break down complex technical and financial concepts and explain them clearly, holding your own with an accountant, an engineer, and a CFO in the same day * Comfort operating as a senior individual contributor - setting direction, making the calls, and leading through influence rather than headcount * Preferred if you've crossed from a finance, accounting, or consulting background into actually building the automation around it - not just specifying it * Preferably hands-on experience with some of the following: * AI agents and LLM-based workflows in a production setting, including the guardrails and monitoring they require * Accounting close and finance automation tooling, and the integrations that connect them OUR STACK Experience with every technology listed isn't expected, we've included them for transparency. What matters most to us is your domain expertise, your curiosity, and your ability to learn - not deep expertise in any one tool. * ERP & finance systems: NetSuite, Zip, and custom billing systems * Automation & integration: Workato, SuiteScript, REST APIs, MCP servers * AI tooling: Claude Code, Codex, Claude  * Data & infrastructure: Redshift, dbt * Languages: SuiteScript, SQL, Python (and a willingness to write whatever the problem needs) We know that diverse teams build better products, and we're committed to creating an inclusive workplace where everyone can thrive. If you're excited about this role but your experience doesn’t align perfectly with every requirement, we still encourage you to apply - your background and skills might be just what we’re looking for! PERKS * Equity stake * Discretionary annual bonus * Flexible work environment, allowing you to work as many days a week in the office as you’d like or 100% remotely * A WFH stipend to support your home office setup * Unlimited PTO * Eligible for the SG discretionary annual bonus based on individual and company performance * Up to 16 weeks of fully-paid family leave  * 401(k) matching  * Student loan matching program * Health, vision, dental, and life insurance * Up to $25k towards family building, reproductive health services and Gender-affirming care * $500 per year for wellness expenses * Subscriptions to Headspace (meditation), Headspace Care (therapy), and One Medical * $360 per quarter to spend on tickets to live events * Annual subscription to Spotify, Apple Music, or Amazon music   ---------------------------------------------------------------------------------------------------------------------------------- The salary range for this role is $127,000 - $183,000 USD. This role is equity eligible. In addition, you may receive a discretionary annual bonus based on individual and company performance.

With 100,000+ active communities and approximately 126 million daily active unique visitors, Reddit is one of the internet’s largest sources of information. For more information, visit www.redditinc.com. TEAM DESCRIPTION This role sits in the Ads Optimization organizations, which are responsible for the health and performance of Reddit’s ads marketplace. We focus on: * Designing the auction and bidding mechanisms that decide which ads show to which users and at what price. * Building optimization systems that help advertisers achieve their goals (e.g., conversions, ROAS) under budget and delivery constraints. * Ensuring marketplace quality by improving user experience with ads, fighting ad blindness, and increasing valuable ad opportunities on the platform. You’ll join a set of tight-knit engineers working on high-impact, internet-scale problems at the core of Reddit’s revenue engine, collaborating closely with Product, Data Science, and Infra partners across Reddit Ads. ROLE DESCRIPTION We are hiring Machine Learning Engineers (IC4) to build and evolve the auction, bidding and budgeting systems that power Reddit Ads. In this role, you will: * Design and implement optimization algorithms for auctions, bidding strategies, and pacing that balance advertiser performance, user experience, and marketplace efficiency. * Own systems end-to-end: from problem formulation and algorithm design to experimentation, production deployment, and ongoing iteration. * Work across Ads Optimization (bid strategies, budget optimization, pacing) to deliver measurable wins for advertisers and Redditors. We are hiring a Senior (IC4)  level: * IC4 MLEs lead more complex or multi-quarter initiatives, set technical direction for key parts of the bidding/auction/pacing stack, and mentor other engineers while remaining hands-on. RESPONSIBILITIES AUCTION, BIDDING, AND PACING SYSTEMS * Design and implement models and policies that: * Compute bids for different optimization objectives (e.g., CPC, CPA, ROAS-based strategies). * Pace budgets smoothly over time across accounts, campaigns, and ad groups while preventing overspend or underspend. * Allocate spend and auction participation intelligently across segments, surfaces, and time zones. * Translate product and marketplace goals into concrete optimization problems and constraints (e.g., ROI, revenue, delivery smoothness, fairness, and user experience). REQUIRED QUALIFICATIONS (Level will be determined during the interview process; IC4 expectations assume deeper experience and broader scope.) * 3–5+ years of experience building, deploying, and operating machine learning systems in production (for IC4, typically 5+ years). * Strong programming skills in Python, Java, Go, or similar languages, with solid software engineering fundamentals. * Experience designing scalable data processing systems (e.g., Spark, Kafka, Airflow, BigQuery, Redis). * Demonstrated ability to translate ambiguous product or business problems into solutions and to improve measurable metrics.   Additional expectations for strong bidding/auction candidates: * Evidence of stronger math and optimization skills than a generic MLE, such as: * Degree or equivalent background in a quantitative field (math, physics, quantitative finance, economics, operations research, or similar). * Work experience in optimization-heavy domains (e.g., bidding/auctions, pacing, pricing, logistics optimization, quantitative finance). * Comfort reasoning about and implementing custom optimization logic (e.g., gradient-based methods, constraint handling), not just applying black-box tooling. PREFERRED QUALIFICATIONS * Experience with advertising/auction systems, online marketplaces, or search/ranking systems at scale, particularly in: * Bidding, pacing, or budget optimization * Auction design, mechanism design, or marketplace quality * Campaign performance optimization (e.g., CTR/CVR, CPA, ROAS) * Familiarity with large-scale, real-time decision systems and low-latency production environments. * Background in feature engineering, model optimization, and production monitoring for ML systems. * Experience collaborating with cross-functional partners (Product, DS, Eng) in Ads or marketplace contexts and leading projects from design through rollout. * Advanced degree (MS or PhD) in Computer Science, Machine Learning, Operations Research, Applied Math, or a related quantitative field. POTENTIAL TEAMS * Ads Optimization (bid strategies, conversion/ROAS optimization, pacing and budget allocation) BENEFITS: * Comprehensive Healthcare Benefits and Income Replacement Programs * 401k with Employer Match * Global Benefit programs that fit your lifestyle, from workspace to professional development to caregiving support * Family Planning Support * Gender-Affirming Care * Mental Health & Coaching Benefits * Flexible Vacation & Paid Volunteer Time Off * Generous Paid Parental Leave  Pay Transparency: This job posting may span more than one career level.
