Full Stack Software Engineer Mid Senior Level

This role is not open to fresh graduates or entry-level applicants

We are exclusively looking for engineers with hands-on production experience. If you are a recent graduate, have under 5 years of professional experience, or have not shipped real e-commerce applications — please do not apply.

✕ Less than 5 years of professional engineering experience

✕ No production experience with Next.js, React, or Node.js

✕ Never built or owned a full e-commerce storefront and backend

✕ No hands-on database work — MongoDB, Supabase, SQL, or NoSQL

✕ Unable to design, build, and manage APIs from scratch

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.

Key Responsibilities

• Frontend — Next.js & React

• 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.

• Backend — Node.js & API Development

• 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.

• Database Architecture & Management

• 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.

• E-Commerce Platform & Integrations

• 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).Context

• Implement product feeds, catalog sync, pricing logic, discount engines, and multi-currency support.

• Collaboration & Communication

• 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.

Skills, Knowledge and Expertise

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.

ODOO Integration Experience

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.

Auto Parts & Automotive E-Commerce

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.
