About the Role

The Onsite Customer Growth team develops features that help Attentive's customers grow through personalized experiences built directly on their websites. We focus on increasing list growth through investments in creative capabilities, experimentation, and AI-driven optimization. Our team builds the systems and product experiences that power onsite engagement for millions of users and help brands convert more visitors into subscribers and customers.

We're looking for a Staff Software Engineer to serve as a technical anchor for the team, shaping not just what we build, but how we build it. This is a role for someone who thinks in systems across multiple teams, drives durable architectural decisions, and accelerates the people around them as much as the product itself. You'll own the most complex, cross-cutting technical challenges in our onsite growth platform and define the technical strategy as the team scales.

This hybrid role is based in our New York office, with in-office collaboration Tuesday through Thursday each week.

What You'll Accomplish

Define and own the technical architecture for Attentive's Onsite Growth platform, setting direction for services, APIs, and shared infrastructure that multiple teams depend on
Lead cross-functional technical strategy in partnership with product, design, ML, and data science teams, driving the most complex, ambiguous problems from alignment to production
Identify and address systemic engineering risks (reliability gaps, scalability ceilings, and architectural debt) before they become blockers to the business
Build scalable backend services, APIs, and user-facing product capabilities that power onsite growth at Attentive's scale
Improve system observability, resiliency, and performance to ensure onsite experiences remain fast, reliable, and effective at scale
Mentor and develop other engineers, giving technical feedback, sponsoring growth, and helping the team level up as a whole
Contribute to a strong engineering culture through principled technical leadership and a consistent focus on customer impact

Your Expertise

8+ years of professional software engineering experience, with a track record of leading complex systems at scale
Demonstrated staff-level impact: you've driven architectural decisions that shaped an entire product area or platform, not just a single feature
Deep proficiency in at least one modern programming language such as Java or TypeScript
Experience designing distributed systems, APIs, and microservices, and a solid understanding of reliability, scalability, and performance
Strong technical communication: you’ve written crisp RFCs, led productive design reviews, and made complex tradeoffs legible to non-engineers
Experience with cloud infrastructure and modern developer tooling (AWS, Docker, Kubernetes, relational databases, caching, queues, streaming)
A history of developing other engineers through mentorship, code review, and raising the standard of work around you
Curiosity, strong collaboration skills, and a genuine passion for building products that drive meaningful customer growth

You'll get competitive perks and benefits, from health & wellness to equity, to help you bring your best self to work.
