Spec-Driven Full-Stack Engineer (AI-Assisted Development)

About the role

Melior builds AI-powered products used daily by more than 110 European companies across telecom, construction, energy and government. It is looking for an onsite full-stack engineer in Islamabad who already uses AI tooling (Claude Code, BMAD, Cursor) as part of their core workflow, not just someone interested in AI. The company follows a disciplined, specification-driven approach: PRDs, architecture docs and technical specs are written first, then AI tools accelerate implementation. The role suits someone who can take a business problem and deliver a production-ready system end-to-end, solo if needed.

Key responsibilities

• Design, implement, test and deploy full-stack systems, including backend services, frontend UIs, APIs and data flows.
• Own features from specification through deployment, including architecture documents, PRDs, technical specs and implementation plans.
• Build AI-assisted workflows and intelligent agents that automate multi-step processes and respond to real-time data.
• Design and integrate billing, payment and financial systems using processor-agnostic architectures.
• Collaborate directly with domain experts embedded in client operations.
• Own architecture decisions, technology selection, deployment strategy and continuous improvement based on client feedback.
• Ensure solutions are scalable, secure, maintainable and production ready.

Required profile

• 5-8+ years of professional software engineering experience across startup and enterprise environments.
• Ability to own the complete technology stack when needed.
• Hands-on experience with cloud platforms and services.
• Strong experience with PostgreSQL, SQL Server and/or MongoDB, and solid understanding of data modeling, database design and query optimization.
• Experience designing microservices, REST APIs and web or mobile clients.
• Proven use of AI-powered development tools such as Claude Code, BMAD or Cursor, in a disciplined, spec-driven manner.
• Preferred: experience with ERP, CMS, FinTech, billing and payments, payroll or mass-payout systems; real-time systems with WebRTC, SignalR or WebSockets; Azure, AWS, CI/CD pipelines and infrastructure automation; working with European enterprise clients.

Required skills

• .NET / ASP.NET Core (with Design Patterns and Standard)
• ReactJS or AngularJS, Node.js with TypeScript or JavaScript
• Docker and containerized deployment workflows
• Integrating third-party APIs and external platforms

What we offer

• Competitive salary, subject to probation clearance.
• 25 holidays and leave encashment.
• Health insurance covering OPD, IPD and maternity separately.
• Fuel allowance, internet allowance and quarterly performance and annual retention bonuses.
• Referral bonus and opportunities for skills development and recognition.
