About Rustica

Rustica is a design and manufacturing company known for custom doors, hardware, and home products. As Rustica expands into a broader home furnishings brand, technology plays an increasingly important role in customer experience, product configuration, order processing, manufacturing, and business operations.

Rustica’s technology ecosystem includes a customer-facing e-commerce storefront, an internal commerce administration platform, a manufacturing and operations platform, and the AWS and Cloudflare infrastructure supporting these applications.

We are seeking a Senior Software Engineer capable of taking technical responsibility for business-critical production systems. This position requires someone who can build new capabilities, improve existing applications, identify architectural risks, and ensure that Rustica’s software and infrastructure remain secure, reliable, and maintainable.

Position Summary

The Senior Software Engineer will serve as a hands-on Technical Lead for Rustica’s customer-facing commerce platform and the supporting systems that connect customers, employees, business operations, and manufacturing.

The primary focus of this position is Rustica’s revenue-critical e-commerce storefront, including product configuration, pricing, cart, checkout, payments, customer accounts, content, and order processing. The engineer will also contribute to Rustica’s internal commerce administration platform and its manufacturing and operations platform, which is being developed to manage production workflows, employee activity, time tracking, operational reporting, and other internal business processes.

This role is also responsible for the AWS and Cloudflare infrastructure supporting Rustica’s applications. This includes deployment, security, monitoring, scheduled workloads, DNS, content delivery, backups, recovery, and production incident response.

This is a hands-on individual-contributor role with technical leadership responsibilities. The Technical Lead designation refers to ownership of architecture, engineering quality, and production reliability; it does not necessarily include direct people management.

This is not solely a feature-development or prototype-building position. The engineer must be able to evaluate existing and rapidly developed code critically, identify unsafe or fragile architecture, and implement production-quality solutions that preserve security and data integrity.

AI-assisted development tools may be used, but the engineer remains responsible for validating architecture, correctness, security, performance, maintainability, and production readiness.

Key ResponsibilitiesE-Commerce and Customer-Facing Systems

• Develop, maintain, and improve Rustica’s customer-facing e-commerce storefront.
• Support complex configurable products involving options, dependencies, dimensions, pricing, discounts, lead times, parts, and bills of materials.

• Develop integrations connecting commerce data with ERP, manufacturing, marketing, shipping, accounting, and reporting systems.
• Automate repetitive business processes while preserving appropriate review, audit, and recovery controls.
• Ensure administrative changes cannot unintentionally compromise storefront behavior or production data.

Manufacturing and Operations Systems

• Contribute to the architecture and development of Rustica’s manufacturing and operations platform.
• Build systems for manufacturing order intake, production workflows, work assignments, employee activity, time tracking, material usage, exceptions, and operational reporting.
• Create trustworthy data models for measuring manufacturing cycle times and identifying production constraints.
• Ensure manufacturing metrics are based on clearly defined and auditable events rather than fragile interface behavior.
• Maintain reliable order delivery from the commerce platform into internal manufacturing and downstream business systems.
• Develop tools supporting inventory, scheduling, maintenance, safety, customer service, IT, and other operational departments.
• Support integrations with CAD, SolidWorks, printing systems, shop-floor equipment, managed devices, and related manufacturing technology when required.
• Help determine when Rustica should build an internal capability and when it should integrate an established external system.
• Review rapidly developed or AI-assisted internal application code before it becomes critical to business operations.

AWS, Cloudflare, and Production Infrastructure

• Administer and improve Rustica’s AWS-hosted applications and supporting cloud services.
• Maintain application hosting, serverless workloads, scheduled jobs, queues, alerts, secrets, permissions, and monitoring.
• Work with AWS services such as Amplify, Lambda, EventBridge, IAM, Secrets Manager, SQS, SNS, CloudWatch, Lightsail, and related infrastructure.
• Maintain repeatable deployments and infrastructure-as-code using tools such as AWS SAM, CloudFormation, and GitHub Actions.
• Manage Cloudflare DNS, CDN and caching behavior, TLS, redirects, security rules, WAF controls, bot protection, and Turnstile.
• Maintain least-privilege access, secure environment configuration, secrets management, and credential lifecycle practices.
