• Improve bidding algorithms through machine learning models to materially lift profitability within the first quarter.
• Architect big-data pipelines and ensure data consistency between the data lake and downstream reporting caches.
• Lead cost-efficiency initiatives that meaningfully reduce data processing spend within six months.
• Maintain a steady delivery cadence against weekly sprint commitments while presenting progress and demos in recurring team standups.
• Participate actively in code reviews and lead periodic internal knowledge-sharing sessions on engineering practices.

Requirements

• Expert-level proficiency in Python, plus strong working knowledge of at least one of Go or Node.js.
• Demonstrated ownership of product-level architecture, projects, and personal deliverables.
• Strong collaboration skills across pair programming, whiteboarding, code reviews, and product or business discussions.
• Comfort presenting in group settings and engaging in daily technical discussions.
• A pragmatic mindset that weighs short-term gains against long-term system stability and is willing to take calculated risks.
• Working understanding of the strengths and pitfalls of AI coding agents, with hands-on experience using them to write, review, and collaborate on code.

Nice to have

• Background operating services at extreme request volumes and managing large-scale data infrastructure.
• Familiarity with PostgreSQL, Iceberg-style data lakes, Vue.js, Docker-based container orchestration, and AWS services such as Lambda, Firehose, and Glue.
• Prior success in a fully remote or hybrid team with periodic in-person collaboration.

Benefits and work setup

• Flexible remote or hybrid work environment.
• Competitive compensation with equity opportunities and performance bonuses.
• 401(k) plus health, dental, and vision coverage.
• Daily lunch stipend, periodic reimbursements for Wi-Fi, cell phone, and subscriptions, plus an annual hardware stipend.
• Flexible paid time off and biannual company offsite gatherings.
