The RoleJoin Qualitate's engineering team as a senior full-stack engineer with end-to-end ownership across backend and frontend infrastructure. You'll architect and ship commercially available APIs and data feeds, build interactive user interfaces and data visualizations in TypeScript and React, and manage infrastructure for reliability, scalability, and security. This is a high-ownership role. You'll work directly with the founding team to define technical strategy and product roadmap, not just execute tickets.
The engineering team is small enough that your decisions shape the product. You'll collaborate with the product and data analytics team to build what customers interact with every day, establish coding, testing, and deployment standards, and troubleshoot complex production issues. We're looking for someone with 5+ years of experience building software who thrives in fast-moving environments where the technical surface area is wide and the team is lean.
Who This Role Is For- 4+ years of experience building software. Ideally some of it in a startup or fast-paced environment where you owned full features end-to-end, not just individual components.
- Strong backend development skills. Experience with Node/TypeScript and frameworks like Express.js. You've shipped commercially available APIs and know how to build them for reliability and scale.
- Strong SQL optimization skills. You can write performant queries, optimize slow ones, and reason about data models at scale.
- Proficient with frontend technologies. Ideally React. You can build interactive user interfaces and data visualizations, not just wire up forms.
- Fluent with AI models and agentic coding tools. You use AI in your daily workflow and understand how to build with and around LLMs. This is core to how we work.
- High ownership, low ego. You work independently, communicate proactively, and don't wait to be told what to build. You're comfortable making architecture decisions and defending them in code review.
What Sets You Apart- You've developed an MCP server.
- Experience with real-time applications and/or WebSockets.
- Previous experience at a startup or high-growth company where you helped define the engineering culture.
- Background in financial services and/or market research.
Compensation & Benefits- Base salary: Competitive, based on experience.
- Equity: Meaningful early-stage grant with upside tied to company growth.
- Benefits: Health coverage, flexible PTO, paid holidays.
- Location: Full-time, in-person in New York City Mon-Weds, remote Thurs-Fri.
What to Expect Working at Qualitate- Excellence. You'll be held accountable to an exceptionally high bar for quality and impact.
- High velocity. Fast-paced environment in terms of growth, decision-making, and time to impact.
- High agency. Ownership over how you work, not just what you work on. We hire people we trust to figure it out.
- A builder's mindset. You'll create the processes, playbooks, and systems that define how this company scales.
- Shared ambition. A small, early team disrupting the multi-billion dollar market research industry with AI.
- Joy. We work hard and genuinely enjoy working together. Dedication to our work is matched only by our passion for fostering an enjoyable, collaborative work environment.
