Hire eCommerce Developers
Bring in senior Shopify, Magento, WooCommerce, BigCommerce and headless commerce engineers who plug into your roadmap within days—not months. Our bilingual squads mirror your ceremonies, protect your velocity and leave lasting improvements to your storefront and operations.
We dedicate a delivery lead and curated developers for every engagement, aligning on conversion goals, operational KPIs and merchandising calendars before we ship. From composable architectures to subscription programs, we have repeatedly helped retailers, DTC brands and marketplaces grow average order value and repeat purchases.
- Checkout and subscription optimization grounded in real analytics
- Migration support (Magento ↔ Shopify Plus, monolith to composable) without downtime
- Data-driven merchandising: site search tuning, personalization, CRM and ERP integrations
Why brands augment with Siblings Software
We operate like in-house eCommerce leaders, not off-the-shelf contractors.
Conversion gains with proof
Our squads arrive with CRO analysts and QA automation. We set sprint scorecards, enforce performance budgets and report uplift on revenue-per-visitor using GA4, Shopify and Looker dashboards.
Commerce-ready engineering culture
Embedded schedules match US and Canadian time zones. We adopt your tooling, run pair-programming sessions and leave behind clean pipelines, observability and documentation.
Strategic partners, not just coders
We facilitate backlog reviews with merchandising, growth and CX teams. Expect candid prioritization conversations backed by customer data, not just code commits.
Many engagements also tap into our web development outsourcing or JavaScript excellence teams to build omnichannel experiences.
Commerce initiatives we deliver
- Composable storefronts using Shopify Hydrogen, Next.js Commerce or Vue Storefront
- Loyalty, referral and subscription programs integrated with Klaviyo, Recharge and Salesforce Commerce Cloud
- Marketplace operations: vendor onboarding, payout automation and catalog normalization
- Contactless retail pilots, BOPIS workflows and headless POS integrations
- Data pipelines that sync ERP, OMS and warehouse tools in near real-time
Case study: NorthStar Furnishings
NorthStar Furnishings, a fast-growing DTC furniture brand, needed to migrate from Magento 2 to Shopify Plus while launching a premium line featuring immersive 3D product previews.
The challenge
Legacy checkout scripts and a custom ERP connector created nightly sync conflicts. Marketing needed to keep campaigns running throughout the migration window.
What we did
We embedded a seven-person pod (Shopify architect, React/Node engineers, QA automation, data engineer and delivery lead). Checkout was rebuilt with Shopify Functions, the ERP integration moved to AWS Lambda + EventBridge, and 3D merchandising widgets were powered by Three.js.
Results in 90 days
- 23% lift in mobile conversion and 17% higher average order value
- Catalog sync errors down by 92%, eliminating manual reconciliation
- Internal team adopted shared playbooks and maintained an NPS of 9.2 with marketing stakeholders
