About Pepper

Pepper is an AI-native organic growth infrastructure company helping enterprise brands get discovered and chosen across search engines, AI answer engines and the AI agents that increasingly influence how customers shop.

Our platform, Atlas, identifies what holds brands back and helps turn those insights into measurable business outcomes.

About the Role

We are looking for a Senior Digital Commerce Engineer to help enterprise brands turn online visibility into completed sales.

You will identify and resolve technical issues across the entire customer journey, from product discovery and evaluation to checkout and payment. This includes understanding how websites render, how search engines and AI agents access content, and where performance, integrations or checkout experiences prevent customers from completing a purchase.

This is a hands-on senior engineering role combining technical consulting, architecture and implementation. You will work directly with enterprise engineering teams, write technical specifications, review implementations and ship fixes across client codebases.

You should have experience working on high-traffic commerce platforms, large product catalogues, multi-market websites and complex technology stacks.

• Identify technical issues affecting discoverability, user experience, conversion and checkout completion.
• Trace problems to their root cause across code, configuration, integrations and data.
• Prioritize fixes based on revenue impact and engineering effort.

2. Architect and advise

• Develop technical specifications and implementation-ready tickets for client engineering teams.
• Review code, pull requests and production releases.
• Advise on rendering strategies, headless versus monolithic architecture, CDN infrastructure, commerce platforms and payment integrations.
• Lead technical discussions with engineering, product, ecommerce and marketing stakeholders.

3. Implement and optimize

• Implement fixes across client codebases, CMS platforms, commerce platforms and edge infrastructure.
• Improve technical SEO, structured data, website performance and Core Web Vitals across large-scale websites.
• Optimize JavaScript, rendering, image delivery, caching and third-party scripts.
• Resolve issues across cart, checkout, payment gateways, shipping, tax and authentication flows.
• Manage large-scale URL migrations and redirects.

4. Measure and monitor performance

• Design analytics data layers, event tracking and server-side tagging.
• Run and evaluate A/B experiments.
• Establish performance monitoring, automated checks and alerts to prevent regressions.
• Connect technical improvements to measurable business outcomes such as conversion and checkout completion.

5. Build reusable systems

• Develop reusable technical playbooks, scripts and automated checks.
• Create validation frameworks for structured data, website performance and technical SEO.
• Identify recurring issues and feed these insights into Pepper's Atlas platform for automated detection.
