What are the responsibilities and job description for the Senior Backend Developer (C# / .NET) position at Clemens Food Group?

Why Join Clemens Food Group

This role sits at the center of one of the most critical technology initiatives in the company. Instead of buying an off-the-shelf application, Clemens chose to build an internal forecasting and availability platform that has become essential to the Fresh Sales team's day-to-day operations. You will help shape the next evolution of this system, influence technical design decisions, and see your work drive real business outcomes.

Clemens invests in its people and expects them to grow. The culture emphasizes measurable results, learning agility, curiosity, integrity, accountability, and doing the right thing.

The Impact You Will Make

You will own and extend the backend services that power forecasting, risk reduction, and availability planning across Fresh Sales. This platform influences pricing, production decisions, customer commitments, and revenue stability. When the business needs answers, your work will enable them to act quickly and confidently.

What You Will Do

  • Build and maintain backend services and APIs using C# and .NET
  • Architect and design new features that support Fresh Sales forecasting and availability planning
  • Manage and compute against very large datasets with an emphasis on performance and asynchronous processing
  • Integrate with SAP, JDA Warehouse Management, and other internal systems
  • Troubleshoot issues and stabilize the application as the team moves toward a steady state
  • Translate business needs into technical design by working directly with Fresh Sales and cross functional teams
  • Participate in three week iterative development cycles and daily stand ups
  • Document code, data flows, and architectural decisions
  • Identify ways to improve performance, optimize data processing, and modernize patterns as needed

What Makes This Role Exciting

  • Ability to architect new backend features from scratch
  • Highly complex computational challenges at meaningful scale
  • Opportunity to propose and use new technologies when they solve real problems
  • Direct partnership with business users who rely on the system every day
  • Clear visibility into how your work affects revenue, forecasting accuracy, and risk reduction
  • Internal ownership of code, not vendor dependency

What We Are Looking For

  • Strong C# /.NET experience and comfort working in API driven services
  • Experience with large data models, asynchronous processing, and performance tuning
  • Strong SQL and understanding of relational data structures
  • Experience integrating with enterprise systems
  • Ability to design backend architecture and reason through tradeoffs
  • Clear communicator who can explain technical decisions to non-technical partners
  • Curiosity, ownership, learning agility, and bias for action
  • Ability to think ahead, anticipate issues, and write defensive code
  • 3 to 6 years of backend engineering experience

Skills And Mindset

  • Delivers measurable outcomes and takes ownership of results
  • Learns quickly and adapts to new tools, domains, and constraints
  • Collaborates well with peers and business partners
  • Demonstrates integrity and alignment with The Clemens Way fundamentals
  • Approaches problems with curiosity, resilience, and disciplined thinking

Your Future at Clemens

You will help mature a high impact internal application, deepen your expertise in backend engineering, and influence architecture for future systems. As the Fresh Sales forecasting tool evolves, you will have opportunities to take on ownership areas, mentor others, and grow into larger responsibilities within Engineering or Product.
