We’re looking for a focused and experienced Software Developer to help maintain and evolve a mature, math- and data-intensive Windows application built on .NET Framework 4.8. The current product is a Windows client backed by a cloud-hosted SQL Server database (AWS), and we’re planning a strategic migration to a future web-based architecture. This role requires deep C# expertise, an eye for performance, and strong software engineering fundamentals—not a jack-of-all-trades, but a disciplined practitioner.

• Maintain and enhance a .NET Framework 4.8 Win Forms desktop application.
• Windows Communication Foundation.
• Optimize performance of MS SQL Server database.
• Hosting services on AWS.
• Ensure software meets GDPR compliance and cybersecurity best practices.
• Design and implement modern authentication approaches (OAuth2, OpenID Connect, etc.).
• Lead architectural planning and migration strategy for a future web-based application.
• Build or extend a CI/CD pipeline to improve testing and delivery workflows.
• Develop and maintain reusable code modules serving similar workflows across multiple user types.
• Produce clear, high-quality graphical outputs and data visualizations.
• Apply A/B testing and user feedback mechanisms to simplify and refine user workflows.
• Integrate AI-assisted tools to improve developer productivity.
• Utilize OpenCV or similar tools for image processing tasks as needed.
• Experience in Material UI, React or similar providing a modern web app experience.

Founded in 2007 and headquartered in Danvers, Massachusetts, Techkon USA is a leading provider of color measurement and quality control solutions for the global printing and packaging industries. We help offset, flexographic, and digital printers streamline their workflows, reduce waste, and deliver consistent, accurate color—ensuring printed products maintain brand integrity and visual impact.

Our tools support mission-critical operations for organizations that depend on high-speed, high-precision color accuracy every day.

Techkon USA has been honored with back-to-back FTA Technical Innovation Awards—a rare achievement in our industry:

• 2024:
  For ChromaQA5 with Smart Ink, an AI-based ink toning solution that dramatically reduces press-side color matching time.
• 2025:
  For Spectro Vision, our inline color measurement system delivering thousands of readings per second across live production.

We continue to invest in new technologies that empower our customers with actionable insights and production control, setting a high bar for quality and innovation in the industry.

This role is ideal for a developer who brings a clear vision for continuous innovation and improvement. You should be comfortable working within a well-defined tech stack while identifying long-term opportunities to modernize and scale the product. We’re looking for someone who can architect our next generation of software, develop an actionable and predictable execution plan, and lead a migration strategy that both supports our current users and positions the product to attract new ones.

A thoughtful, systems-level mindset and a strong sense of ownership are essential for success in this role.

• 5+ years of professional experience in C# and the .NET ecosystem.
• Skilled in SQL Server development, performance tuning, and cloud-based deployments (preferably on AWS).
• Familiar with security compliance standards such as GDPR and secure coding practices.
• Experience with modern identity and access management (OAuth2, SSO, etc.).
• Strong architectural thinking, with experience planning migrations or long-term application transitions.
• Exposure to CI/CD tooling and implementation strategies.
• Comfortable analyzing and visualizing numerical data with graphical accuracy.
• Familiarity with OpenCV or similar image processing tools.
• Clear, pragmatic communication skills and team-oriented mindset.
