Forward Deployed Infrastructure Engineer at Sirius

Job Title: Forward Deployed Infrastructure Engineer

About the role

Sirius is an early-stage startup building high-performance embedded infrastructure for business metrics and customer data. We empower companies to drop powerful, data-dense widgets and SDKs directly into their products, focusing on conversion-critical flows and seamless user experiences at the intersection of fintech and analytics.

Responsibilities

• Own the end-to-end lifecycle of our core embedded product.
• Build high-performance SDKs and widgets that live inside customer applications, optimizing for bundle size and load speed.
• Combine deep frontend engineering with a focus on business-critical metrics like conversion and retention.
• Develop and maintain third-party scripts, iframes, and SDKs designed to be embedded directly into diverse customer environments.
• Optimize load performance and minimize bundle sizes to ensure our one-line SDK never degrades the performance of a host site.
• Build data-dense dashboards and consoles that clearly visualize offer performance, churn signals, and cohort data for end-users.

Requirements

• Proven experience building B2B SaaS interfaces or fintech UI for companies specializing in conversion-critical flows and analytics.
• Expertise in developing embeddable widgets or snippets that maintain high trust signals while living inside another company's product.
• Previous experience at a Seed or Series A startup with a track record of iterating on existing codebases rather than just greenfield projects.

Qualifications

• Strong understanding of web technologies including JavaScript, HTML, CSS, and frameworks/libraries such as React, Angular, or Vue.js.
• Experience with performance optimization techniques and tools like Lighthouse, Webpack, and Rollup.
• Knowledge of data visualization libraries such as D3.js, Chart.js, or Highcharts.
• Ability to work independently and manage multiple projects simultaneously.
• Excellent communication skills and ability to collaborate effectively with cross-functional teams.

Note: This is an open role that Jill is currently recruiting for from Jack's network. Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description. We appreciate this can make them look a bit suspect, but there isn't much we can do about it. Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
