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! The Division Constellation HomeBuilder Systems is a leading software provider focused exclusively on the homebuilding industry. Its comprehensive suite of software solutions supports production and accounting, new home sales and marketing, home warranty and service, and homebuilder website solutions. The organization provides integrated information‑management solutions designed specifically for homebuilders.

The Position

We are looking for a Senior Database Performance Engineer to join the NX R&D team. The successful candidate will take a hands‑on role in analyzing, troubleshooting, and improving the performance of enterprise applications, with a strong focus on Microsoft SQL Server. The role requires someone who can investigate performance issues across the application stack and identify whether bottlenecks originate within the database, application, IIS, or underlying Windows environment. The ideal candidate will have strong SQL Server performance‑engineering expertise and experience taking ownership of performance analysis and optimization initiatives. The hired candidate will work from the Contour Software Karachi office as an extension of the division‑based R&D team, with working‑hours availability until 3:00 PM Eastern Time.

Responsibilities

Own and drive database and application performance analysis and optimization initiatives. Diagnose and resolve SQL Server performance bottlenecks involving complex queries, stored procedures, and database workloads. Analyze SQL Server execution plans and recommend appropriate indexing and query optimization strategies. Diagnose issues involving statistics, parameter sniffing, blocking, and deadlocks. Use Query Store, Extended Events, Dynamic Management Views (DMVs), and wait statistics to identify and troubleshoot database performance problems. Design, develop, and optimize complex T‑SQL queries, stored procedures, functions, views, CTEs, and window functions. Investigate IIS and Windows Server performance issues using application pools, worker‑process CPU and memory utilization, IIS logs, failed‑request tracing, and Performance Monitor. Trace slow requests end‑to‑end using IIS logs, application logs, and Application Insights. Determine whether performance bottlenecks originate within the application, database, or infrastructure layer. Collaborate with developers, QA, and other technical team members to identify root causes and implement sustainable performance improvements. Assist teams in establishing appropriate performance baselines and identifying opportunities for proactive optimization. Document findings, recommendations, and changes resulting from performance investigations. Work closely with both onshore and offshore team members to deliver high‑quality solutions within agreed timelines.

Qualifications and Skills

Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related field. 4+ years of hands‑on Microsoft SQL Server development, performance engineering, or DBA experience. Hands‑on experience with SQL Server 2022 or later. Expert‑level T‑SQL, including complex queries, stored procedures, functions, views, CTEs, and window functions. Strong understanding of SQL Server execution plans and query optimization. Strong knowledge of indexing strategies, statistics, and database performance tuning. Practical experience diagnosing parameter sniffing, blocking, and deadlocks. Hands‑on experience with Query Store, Extended Events, DMVs, and wait statistics. Working knowledge of IIS and Windows Server diagnostics. Experience with Application Insights and application‑level performance troubleshooting. Ability to trace an application request end‑to‑end and distinguish database‑related bottlenecks from application‑related issues. Strong analytical and root‑cause‑analysis skills. Excellent verbal and written English communication skills. Ability to collaborate effectively with geographically distributed development and QA teams. Experience working with enterprise ERP or other large transactional systems would be an asset. Homebuilding‑domain experience would be an advantage.
