[Hiring] Lead Engineer, Member Growth @Circle

Role Description

Circle’s Growth team owns three pillars: Billing, Analytics, and Member Growth. We’re looking for a Lead Engineer to own Analytics and Member Growth. This is a hands-on role where you’ll write a lot of the code, make hard technical calls, and lead a small team of tenured engineers.

You’ll own two things:

• How digital business owners understand what’s happening in their business, including the analytics Circle AI uses to answer their questions.
• How a new member goes from signing up to actually showing up.

Millions of people join and use Circle every month, so small changes here have an outsized impact.

What you'll be doing:

• Leading, growing, and coaching a team of engineers across Analytics and Member Growth, while remaining hands-on — reviewing designs and PRs, and shipping code yourself daily.
• Owning the technical strategy and architecture for Circle's analytics stack: rich, interactive data visualizations, ClickHouse data infrastructure, and LLM-powered experiences.
• Owning the roadmap for Member Growth: onboarding flows, activation, and reducing friction for new member engagement.
• Partnering with product, design, data, and leadership to turn ambiguous problems into a cohesive, data-informed growth roadmap with measurable outcomes.
• Working AI-first: using agents for planning, coding, review, and triage; staying critical of their output.
• Designing and overseeing A/B tests and experimentation to validate changes that improve activation, retention, and community health.
• Hiring, mentoring, and developing engineers, and running performance and career-growth processes for your team.

Qualifications

• Prior experience leading or managing engineering teams.
• A product mindset: understanding customers deeply enough to question and shape requirements.
• 7+ years of experience shipping production software on complex web applications.
• Strong track record in data/analytics infrastructure or growth/lifecycle product engineering.
• Comfortable in highly collaborative environments.
• Ability to operate well in ambiguous, fast-moving problem spaces.
• Strong alignment with our values.
• Exceptional written and verbal communication skills in English (CEFR C2 or equivalent).

Requirements

• Experience with Ruby on Rails, MySQL/PostgreSQL, ReactJS, and TypeScript.
• Experience shipping LLM-powered product features.
• Familiarity with billing tools or payments infrastructure (Stripe).
• Experience working in a growth-oriented or PLG engineering organization.

Benefits

• U.S.-benchmarked compensation globally.
• Equity in the company with ongoing refresh grants.
• 35 days of paid time off each year.
• Incredible flexibility and autonomy.
• Benefits package that supports health, wellbeing, and professional growth.
