Full Stack Developer — Shopify & Custom Apps

About the Role

We’re looking for a Full Stack Developer to join the delivery team of Kaldway Technology Group (KTG), a U.S. technology partner, to build and maintain e-commerce and web applications for its clients. The work covers Shopify storefronts, custom backend services, third-party integrations, and internal tooling.

You’ll work directly with a small team, client stakeholders, and design partners, and you’ll own your work from the first conversation about requirements through to production support. This is a hands-on role with real production ownership, as an embedded member of KTG’s team with U.S. time-zone overlap.

What You’ll Own

Shopify & Front End

• Build and customize Shopify storefronts, including themes, cart and checkout logic, and account and subscription experiences.
• Implement front-end designs from Figma with attention to accessibility, performance, and mobile.

Backend, Integrations & Automation

• Build and maintain backend services and APIs, including webhook-driven workflows and background jobs.
• Integrate third-party platforms such as subscription, payments, reviews, loyalty, search, and project management tools.
• Build data pipelines, reporting, and automation, including LLM-powered workflows where they fit.

Maintenance & Delivery

• Maintain and improve existing applications, including inherited codebases: fix defects, pay down technical debt, and manage hosting migrations.
• Turn ambiguous requests into clear technical questions, flag risks early, and document decisions.
• Take part in estimation, code review, and release planning.

Technical Requirements

Required

• 4+ years of full stack experience, with real production ownership.
• Strong JavaScript/TypeScript, with Node.js on the backend and React on the front end.
• Hands-on Shopify development: Liquid themes, the Admin and Storefront GraphQL APIs, webhooks, and metafields and metaobjects. Experience with Shopify Functions, Checkout or Admin UI Extensions, or Shopify Flow is a plus.
• Experience integrating third-party APIs, and the judgment to anticipate where an integration can fail silently.
• Solid backend fundamentals: PostgreSQL, caching, and designing for at-least-once webhook delivery (idempotency, retries, race conditions).
• Working knowledge of AWS and CI/CD. Infrastructure as code is a plus.
• Clear written and spoken English, and comfort working directly with clients.

Nice to Have

• Experience with subscription or B2B commerce.
• Experience building LLM-powered agents or automations.
• Data engineering experience, such as warehouses, BI tools, and ETL connectors.
• Experience with compliance-sensitive flows, such as consent capture, OTP or passwordless login, and regulated products.
• Experience taking over and stabilizing inherited codebases.

AI-First Engineering Culture

At NearShift, AI isn’t a side project — it’s how we work. In this role you’ll use AI tools to move faster across storefront, backend, and integration work, and you’ll build LLM-powered workflows and automations for clients where they add real value. We look for engineers who are curious about where commerce engineering and AI meet.

Core Competencies

• Ownership — from the first requirements conversation to production support.
• Judgment about failure modes: you think about what happens when a webhook arrives twice, late, or never.
• Turning ambiguity into clear questions and documented decisions.
• Clear, direct communication with clients, designers, and engineers.
• Care for accessibility, performance, and the mobile experience.
• Proactivity, continuous improvement, and AI-first thinking.

What We Offer

Compensation & Benefits

• Competitive salary based on your experience and skills.
• Full-time employment contract with NearShift S.A.S. under Colombian labor law.
• Prepaid health plan (Sura).
• A day off on your birthday, plus the Colombian holiday calendar.
• Flexibility in vacations, schedules, and work policies.
• USD 300 referral bonus for every referred candidate who joins NearShift.
• Fully remote work with U.S. time-zone overlap, and access to cutting-edge AI tools and platforms.

Career Growth

• Long-term placement with Kaldway Technology Group and the clients it serves.
• Direct work with U.S. client stakeholders and design partners.
• Variety across storefronts, custom apps, integrations, and data work.
• A path to grow into senior and tech-lead roles.

Hiring Process

• Intro call (30 min). Get to know each other, the role, and KTG.
• Technical conversation (60 min). Walk us through a Shopify build or third-party integration you took to production, and how you handled the ways it could fail.
• Final conversation with the KTG team.
