[Hiring] Senior Software Developer, E-Commerce Systems @Lago

Role Description

We are looking for a Software Developer to work alongside our lead developer in extending and improving our e-commerce platform. Much of the work involves solving practical business problems:

• Fixing unreliable vendor feeds
• Clarifying and improving pricing logic
• Building APIs
• Improving product data quality
• Replacing manual spreadsheet workflows with dependable software

What You'll Work On:

• Product data: Vendor imports and feeds, in-house PIM, categorization, images, and data quality across a large, inconsistent catalog.
• Inventory and pricing: Feed ingestion (AWS Lambda, S3, SFTP), scrapers for vendors without feeds, and the pricing, deals, and cart logic that depend on them.
• The storefront API: Building and testing the API endpoints for the new site replacing Shopify with our own Django backend and React Router storefront.
• Search: Elastic search-backed search, facets, and recommendations.
• Internal tools and automation: Finding manual, repetitive work across the business and replacing it with reliable solutions.
• Infrastructure: Moving hand-built AWS and Cloudflare resources to OpenTofu.

Qualifications

• Strong Python programming skills and experience building production software.
• Solid SQL and PostgreSQL knowledge, including the ability to investigate query performance.
• Solid experience building and consuming APIs (Django Ninja, Pydantic, or OpenAPI).
• Experience processing real-world data from CSV or Excel files, external feeds, scraping, or ETL pipelines.
• Sufficient React and TypeScript experience to contribute to frontend work when required.
• Strong testing practices, including assertions against specific business outcomes rather than response status alone.
• Good engineering judgment when choosing between scripts, application features, process improvements, and AI-based automation.
• Clear written communication for pull requests, technical documentation, tickets, and collaboration.
• Ability to investigate unfamiliar systems, work independently, and deliver maintainable solutions.

Requirements

• Hands-on experience with Django, including its ORM, migrations, and admin tools.
• Familiarity with Django Ninja, Pydantic, OpenAPI, or similar API development tools.
• E-commerce experience involving product catalogs, PIM, order management, checkout, or Stripe.
• Experience with Elasticsearch or another major search platform.
• Familiarity with AWS Lambda, S3, ECS, Cloudflare Workers, or OpenTofu/Terraform.
• Experience working with large product catalogs or data-intensive retail systems.
• Practical experience using AI coding assistants in a reviewed, test-driven development workflow.

Benefits

• Remote Work: Work from anywhere—our team is global, and we value work-life balance.
• Growth Opportunities: As a key player, you’ll have the chance to shape your role and grow with us.
• Innovative Culture: Join a team that is passionate about leveraging data to solve challenges and drive success in a rapidly evolving market.
