About The Position

We are looking for a highly experienced Full Stack Software Engineer to join our onsite team in Islamabad. You will own the full development lifecycle of e-commerce web applications — from database architecture and API design to frontend delivery using Next.js and React. You must have deep MERN stack experience, strong database skills across SQL and NoSQL, and a proven background in the e-commerce space. Experience with ODOO integrations, auto parts platforms, or automotive data standards (ACES / PIES) is a significant advantage.

Requirements

• 5+ years of professional software engineering, with at least 3 years in e-commerce full-stack development.
• Expert in Next.js (SSR, SSG, ISR, App Router) and React — production applications required.
• Strong Node.js and Express.js backend skills — API design, middleware, auth, and performance tuning.
• Hands-on experience with MongoDB (schema design, aggregations, indexes) and Supabase / PostgreSQL (queries, RLS, migrations).
• Comfortable working with both SQL and NoSQL databases — understands when to use each.
• Built and deployed at least one full custom e-commerce website (storefront + backend + database) from scratch.
• Experience with Docker, CI/CD pipelines, and cloud deployment (Vercel, AWS, GCP, or equivalent).
• Excellent written and verbal English communication skills — able to present and document clearly.

Nice To Haves

• Experience with ODOO integrations, auto parts platforms, or automotive data standards (ACES / PIES) is a significant advantage.
• Experience integrating ODOO (ERP) with web applications — product sync, inventory, order management, or customer data flows.
• Familiarity with ODOO's REST or XML-RPC APIs and connecting them to a Next.js / Node.js stack.
• Prior experience building or working on auto parts e-commerce websites — fitment filters, vehicle selectors, part compatibility logic.
• Understanding of ACES (Aftermarket Catalog Exchange Standard) and PIES (Product Information Exchange Standard) data formats.
• Ability to ingest, normalise, and expose ACES/PIES datasets via APIs or database structures for search and fitment filtering.
• Experience handling large automotive parts catalogs with complex taxonomy, fitment tables, and cross-reference data.
• Shopify knowledge is welcomed but not required — we use it as a gauge of e-commerce exposure, not as a job requirement.

Responsibilities

• Build fast, SEO-optimised storefronts and web apps using Next.js (App Router / Pages Router) and React.
• Implement server-side rendering (SSR), static site generation (SSG), and incremental static regeneration (ISR) based on use-case requirements.
• Build reusable component libraries with state management via Redux, Zustand, or Context API.
• Optimise for Core Web Vitals, mobile-first responsiveness, and cross-browser compatibility.
• Design, build, and maintain RESTful and GraphQL APIs using Node.js and Express.js.
• Handle complex business logic: product catalog, cart, checkout, order management, and fulfillment pipelines.
• Implement authentication and authorisation using JWT, OAuth 2.0, and role-based access control (RBAC).
• Write clean, testable Node.js code with solid understanding of the event loop, streams, and async patterns.
• Integrate third-party services: payment gateways (Stripe, PayPal), shipping APIs, and tax engines.
• Design and manage MongoDB schemas for high-volume e-commerce data — products, variants, inventory, orders, and users.
• Set up, configure, and manage Supabase (PostgreSQL) for relational data needs, including row-level security and real-time subscriptions.
• Work confidently with both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases — selecting the right tool based on data shape and access patterns.
• Write efficient queries, design proper indexes, and optimise slow queries in production environments.
• Handle database migrations, seeding, backups, and schema versioning.
• Build custom e-commerce storefronts and backends outside of managed platforms — full ownership of architecture and delivery.
• Integrate and work within headless commerce architectures using Medusa.js or custom-built commerce engines.
• Work with e-commerce tools and platforms (Shopify knowledge is welcomed but not required — we use it as a gauge of e-commerce exposure, not as a job requirement).
• Implement product feeds, catalog sync, pricing logic, discount engines, and multi-currency support.
• Communicate technical decisions clearly to engineers, PMs, and non-technical stakeholders in English.
• Produce technical documentation, API references, and architecture decision records (ADRs).
• Lead and participate in code reviews with a constructive, knowledge-sharing mindset.
• Proactively flag blockers, contribute to sprint planning, and own feature delivery end-to-end.
