About Contour

Contour Software has grown from a dozen people to over 2,000 staff across 3 cities, in less than 14 years. As a subsidiary of Constellation Software Inc., we are proud to be part of a global enterprise software conglomerate that has grown to become one of the top 10 software companies in the world, with employees and customers in 100 countries. With a broad-based and ever-growing portfolio of market-leading, vertical-market enterprise solutions covering more than 100 industry domains in predominantly mature markets, CSI's recipe creates the perfect environment for professionals to build fulfilling, long-term careers. What started as an R&D & Accounting back-office, has progressed into a full-service Global Centre serving all functions and departments, at the divisional as well as operating group/corporate level. Today Contour employees, located in Karachi, Lahore & Islamabad, are serving CSI divisions located in time zones spanning the globe, from Sydney to Vancouver. With the global growth of Constellation as the wind in our sails, we are only just getting started!

We're hiring a senior developer to help build our new web products, from the user interface to the services and database behind it.

This is a hands-on role for an engineer who already uses AI tools every day and wants to help shape how a modern product team works. We're adopting an AI-Driven Development Lifecycle (AI-DLC) approach, where AI takes on more of the planning and building while engineers set direction, review the work, and make the decisions that matter. You'll help us do this well: shipping quality product, keeping human judgment in the right places, and sharing what works with the team. You'll report to our Dev Manager and work with the Modernization development team, with Product, and with Infrastructure & IT on deployment and cloud needs.

Our tech stack

• Back end: .NET/C#, ASP.NET Core APIs
• Front end: React, TypeScript
• Data: SQL Server
• Cloud: Azure
• Delivery and tooling: GitHub, GitHub Actions, Linear, Claude Code

What You'll Accomplish In Your First Year

• First 90 days: Get up to speed on our codebase and architecture. Ship your first features with Claude Code inside an AI-DLC workflow, with clear review in GitHub. Start sharing what works with the team.
• By 6 months: Own a significant feature area from planning through release. Help the Modernization team set consistent practices for AI-assisted development, including how we use Claude Code, review AI-generated code, and track work in Linear.
• By 12 months: Lead design decisions for major parts of the new web products, including data model design and database performance. Help the team grow its AI-DLC practice.

Responsibilities

Product development

• Design, build, and test features across the full stack: back-end APIs, the data layer, and the user interface.
• Turn product requirements into clear, buildable work with Product and the Dev Manager.
• Keep code clean, tested, and maintainable, so the next engineer can work in it with confidence.

AI-assisted development

• Use Claude Code as a regular part of your daily work: planning, implementation, tests, refactoring, and code review.
• Apply AI-DLC practices, with AI handling much of the planning and building and clear human checkpoints.
• Review AI-generated code critically, and catch mistakes before they reach production.
• Help create shared team guidance, such as reusable instructions, workflows, and standards for AI-assisted work.

Collaboration and delivery

• Work in GitHub for source control, branching, pull requests, and code review.
• Track work in Linear, keeping status current and scope clear.
• Partner with Infrastructure & IT on deployments, environments, and production issues.
• Mentor teammates and raise the bar on code quality and design.

Required Qualifications

• 6 years of professional software development, including at least 3 years building production APIs and services in C# and ASP.NET Core.
• Hands-on experience building production user interfaces in React and TypeScript.
• Strong database skills in SQL Server, including schema design, complex queries, and performance tuning.
• Experience writing automated tests for back-end and front-end code, such as xUnit and Vitest.
• Daily, hands-on use of Claude Code or a comparable agentic coding tool, with examples you can walk us through.
• A working understanding of AI-DLC and how it changes planning, review, and team workflows.
• Strong Git and GitHub experience, including pull requests and code review.
• Experience with CI/CD pipelines, ideally GitHub Actions.
• Senior-level ownership: you can scope work, make tradeoffs, and see a feature through to release.
• Good judgment about where AI helps and where it doesn't, with a habit of testing and verifying AI output.

Nice to have

• Experience moving customers or products from legacy desktop software to web applications.
• Experience building AI-assisted workflows for a team, such as custom skills, agents, or MCP integrations.
• Experience with Linear or similar work-tracking tools.
• Azure experience, since our cloud environment runs on Azure.
• Experience choosing and adopting proven open-source libraries and tools, so we move faster and only write the code we truly need.
• Enough Terraform to read our infrastructure code and make small changes alongside our infrastructure team.
• Familiarity with OAuth and OpenID Connect (OIDC) for authentication and authorization.
• Experience working in a monorepo.
• Experience with end-to-end and browser testing, such as Playwright.
• Experience at a company with long-lived products that are being modernized.
