Lead Engineer, Member Growth

Circle is building the world’s leading AI-powered, all-in-one platform for digital businesses. We make it possible for creators, coaches, educators, and businesses to bring together their audience with engaging discussions, live streams, events, chat, courses, and payments — all in one place, all under their own brand.

We’re proud to be a fully remote company of around 270 (and growing!) team members from 30+ countries around the world. We seek exceptional individuals around the world, set them up to do the best work of their lives, and in turn, create a meaningful impact in their own lives. We don't track hours, but we do manage for high expectations very closely. We collaborate across time zones, are highly async, and like to document a lot.

Every year, we bring the whole company together in beautiful places around the world for our company offsites. So far, we’ve hosted offsites in Turkey, Portugal, Mexico, Thailand, Colombia, Italy, Ireland, and more, with still more to come!

Circle’s Growth team owns three pillars: Billing (SaaS billing, experimentation, PLG and sales-led funnel infrastructure), Analytics (data visualization and architecture, ClickHouse, and LLM-powered analytics Q&A), and Member Growth (onboarding, activation, and removing the friction that keeps a business from growing).

We’re looking for a Lead Engineer to own Analytics and Member Growth. This is a hands-on role. You’ll write a lot of the code, make the hard technical calls, and lead a small team of tenured engineers. Most of your week goes to building and reviewing. The rest goes to running the team: 1:1s, planning, and helping people grow.

You’ll own two things. First, how digital business owners understand what’s happening in their business, including the analytics Circle AI uses to answer their questions. Second, 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.

• 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 that enable business owners to ask questions about their data in natural language.

• Owning the roadmap for Member Growth: onboarding flows, activation, and reducing the friction that stands between a new member and real engagement in a community.

• Partnering with product, design, data, and leadership to turn ambiguous problems into a cohesive, data-informed growth roadmap with measurable outcomes.

• Work AI-first. Use agents for planning, coding, review, and triage; stay critical of what they produce and help the team build shared tools that make all of us faster.

• 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.

• Prior experience leading or managing engineering teams. You’ve led engineers on large initiatives. You set direction, reviewed their work, and helped them get better while staying one of the strongest builders on the team.

• A product mindset: you understand our customers deeply enough to question and shape requirements, not just implement them. You're comfortable making fast, independent decisions following SaaS/product best practices.

• 7+ years of experience shipping production software on complex web applications, including experience with Ruby on Rails, MySQL/PostgreSQL, ReactJS, and TypeScript.

• Strong track record in at least one of: data/analytics infrastructure (e.g., ClickHouse, data warehousing, BI), or growth/lifecycle product engineering (onboarding, activation, retention); exposure to both is a strong plus.

• Comfortable in highly collaborative environments, working closely with stakeholders across engineering, product, design, and go-to-market teams.

• Ability to operate well in ambiguous, fast-moving problem spaces and translate findings into clear priorities for your team.

• Strong alignment with our values (find our values on our career page if you haven't read up on them yet).

• Exceptional written and verbal communication skills in English (CEFR C2 or equivalent), as most collaboration at Circle happens asynchronously. 

• Experience shipping LLM-powered product features, such as natural-language data Q&A or AI agents.

• Familiarity with billing tools or payments infrastructure (Stripe).

• Experience working in a growth-oriented or PLG engineering organization.

Circle offers U.S.-benchmarked compensation globally, equity in the company with ongoing refresh grants, and 35 days of paid time off each year.

We’re a remote-only team that comes together twice a year for company retreats in incredible destinations around the world. Alongside incredible flexibility and autonomy, we offer a benefits package that supports health, wellbeing, and professional growth. Learn more in our Candidate Hub.
