Senior Fullstack Engineer, Data & Finance (USA Only - 100% Remote)

Close is a bootstrapped, profitable, 100% remote, ~100 person team of thoughtful individuals who prioritize taking ownership and making a meaningful impact. We’re eager to make a product our customers fall in love with over and over again.

We 💛 small scaling businesses. Since 2013, we’ve been building a CRM that focuses on better communication, without the hassle of manual data entry or a complex UI. We are out to supercharge sales productivity with the most modern, thoughtfully designed, all-in-one, communication-focused CRM.

We love open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check out our open source projects like: Backend -SocketShark, TaskTiger, LimitLion and ciso8601 & Frontend - react-custom-scroller, use-infinite-scroll, use-abortable-effect, and smart-tooltip-delay.

We’re looking for a Senior Engineer to join our Finance + Data Team. This is an unconventional but high-impact role at the intersection of systems, data, product analytics, GTM analytics, and AI. You will be trusted with connecting and building the software that powers smarter, faster decision-making for our business.

Today, our data, dashboards, and insights are spread across disconnected systems. As part of a small Finance + Data team, you’ll focus on improving how these systems communicate, building the underlying infrastructure that enables Product, GTM, and Leadership teams to access the right insights at the right time.

But beyond unifying GTM, Finance, and Product data, automating workflows, and building scalable integrations — you’ll lay the foundation for our own AI-enabled insights and internal tools, such as churn forecasting or internal AI agents that can surface contextual business intelligence. (Think: an agent that can whip up a Monthly Business Review with all the relevant, important information.) We’re eager to invest in advanced AI-powered internal tooling that will move the needle, and this Senior Engineer will be responsible for helping us build the brain and backbone of a next-generation business engine.

• A Senior+ engineer with 5+ years of experience in a hands-on software engineer, data engineer, or systems engineer role with a proven ability to build scalable systems at the intersection of data, business, and product.

  • Full-stack working experience using Python/TypeScript/JavaScript to build data analytics and back office applications

  • Working knowledge of product analytics instrumentation in SaaS apps

  • Querying and implementing ETL processes across disparate databases

  • Familiar with modern cloud data stacks (e.g., dbt, Fivetran, Snowflake)

  • Experienced with implementing and managing product analytics tools (e.g., Amplitude, Mixpanel, Segment)

  • Experienced with (or excited by!) AI and statistical or other machine learning concepts like predictive modeling, AI agents, and automation to enhance workflows and decision-making

• Comfortable owning the full lifecycle: from scoping business needs to designing, building, and delivering and maintaining technical solutions. While you’ll work closely and collaboratively with the Finance + Data team, we expect you to be your own Product Manager in many ways. You’ll interface with different teams, scope the work that solves their problems, and translate it to technical deliverables.

• Excited by and attuned to the mechanics of modern SaaS businesses. You’ll need to understand and deeply integrate yourself into various functions at Close to best empower our team.

• Driven by a strong sense of accountability and ownership. As a pioneer in this role and the only dedicated Engineer working on these problems, you’ll be responsible for the implementation, effectiveness, and maintenance of your work.

• Located in the US (ET, CT, MT, PT)

• Architect, build, and maintain integrations between GTM systems, product analytics platforms, and data warehouses.

• Own administration and optimization of key platforms, ensuring data integrity and usability.

• Collaborate with Product and Engineering to instrument events, validate data, on product usage and engagement

• Partner with Sales, Marketing, Product, and Finance to translate business needs into robust technical solutions

• Build automation and AI-enabled tools to reduce manual work and improve decision-making.

• Competitive compensation including an organization-wide goal-based bonus

• Paid Time Off: 5 Weeks PTO upon joining + Winter Holiday Break. Each year with the company, you’ll receive 2 extra PTO days.

• 80% Work Option: Work with your manager to choose between working 5 day weeks (standard full-time) or 4 day weeks @ 80% pay

• Paid Parental Leave for primary and secondary caregivers

• Sabbatical: After 5 years with the team, you’re eligible for a 1 month paid sabbatical

• Healthcare (US residents): Medical, Dental, Vision with HSA option (US residents), Dependent care FSA (US residents)

• 401k (US residents): We match 6% contributions with immediate vesting
