Staff Product Engineer

About the role

Summation is building the future of business planning and analytics by bridging the gap between data and decision-making. We empower organizations to transform complex data into clear, actionable insights that drive business outcomes. Our AI-native platform pairs advanced data models with intuitive workflows to make enterprise performance management simple, collaborative, and effective.

Key Responsibilities

• Own the front-end architecture and user experience of our product end-to-end from concept through shipping and iteration
• Set the bar for front-end quality, patterns, and performance, and help establish the standards the team builds against
• Partner directly with the CTO, Founding Designer, and product team to shape direction and translate ambitious ideas into polished, performant interfaces
• Build responsive, scalable, data-dense interfaces for analytics and AI-driven workflows
• Bring a strong product perspective to engineering decisions, advocating for the user at every step

Qualifications

• 8+ years of software engineering experience, including 4+ years of dedicated, hands-on front-end product development — building products, not solely platform or library work.
• Experience building and shipping a product from zero to one with end-to-end ownership, as a founding or early engineer at a startup or with equivalent ownership inside a larger company
• A track record of shipping to internal or external users and iterating based on their feedback
• Strong communication and problem-solving skills, ability to work with cross-functional teams
• Proficiency in Python, TypeScript, JavaScript, or similar languages

Nice to Have

• Hands-on experience building interfaces backed by LLMs or agent frameworks
• Background in analytics, data visualization, or AI-driven products
• Familiarity with financial software, models, or data
• Experience leading or mentoring engineers (not required for this role)
