How to Apply for Principal Engineer

at ICAP Energy AS

🏢 About ICAP Energy AS

ICAP Energy AS is a specialized energy and commodities broker focused on driving sustainable markets through innovation. Unlike traditional brokers, they combine deep market expertise with technology-driven solutions, positioning themselves at the intersection of finance, energy transition, and high-performance systems. Working here offers the chance to impact global energy markets while solving cutting-edge technical challenges in a mission-critical environment.

About This Role

As Principal Engineer, you'll be the technical linchpin for strategic R&D, algorithmic optimization, and cross-team leadership at ICAP Energy. This role specifically owns the Pricing Distribution layer architecture, requiring microsecond-latency optimizations and deep audits of C++ execution algorithms in trading systems. You'll influence technical direction across regions without direct authority, making this a high-impact position for someone who thrives on solving complex problems in fast-paced financial environments.

💡 A Day in the Life

Your day might start with a deep dive into CLR performance metrics from overnight trading sessions, followed by reviewing a Proof of Concept for a new pricing distribution mechanism. You'd spend midday collaborating with teams in different regions to align on engineering standards, then audit a complex C++ algorithm showing latency issues. The day would wrap with preparing data-backed recommendations for a 'Build vs. Buy' decision on a new market data technology.

Practice questions for this role

🎯 Who ICAP Energy AS Is Looking For

  • A senior engineer with 8+ years experience evolving complex, low-latency systems in financial services or trading environments, not just general software development
  • Deep expertise in C#/.NET Core CLR internals, garbage collection optimization, and the ability to audit complex C++ pricing algorithms—this requires true polyglot proficiency
  • Proven ability to conduct data-driven 'Build vs. Buy' analyses with concrete performance benchmarks for leadership, not just theoretical recommendations
  • Strong quantitative background with experience understanding pricing flows and trading strategies, bridging the gap between pure engineering and quantitative finance

📝 Tips for Applying to ICAP Energy AS

1

Highlight specific examples where you optimized .NET Core CLR performance or garbage collection in low-latency systems—quantify the latency improvements

2

Demonstrate your experience with pricing distribution systems or similar financial data dissemination layers, emphasizing microsecond-level optimizations you've implemented

3

Showcase your 'scout' capabilities by mentioning specific frontier technologies you've evaluated through Proof of Concepts in financial contexts

4

Provide concrete examples of influencing technical decisions across teams without direct authority, especially in multi-region environments

5

Include metrics from your 'Build vs. Buy' analyses—actual performance comparisons, cost savings, or risk assessments you've presented to leadership

✉️ What to Emphasize in Your Cover Letter

['Your experience with pricing distribution systems and microsecond-latency optimizations in financial environments', 'Specific examples of auditing complex C++ algorithms and improving execution performance in trading systems', "How you've acted as a technology scout, evaluating emerging tools with Proof of Concepts that led to data-backed recommendations", 'Your approach to establishing engineering standards and ensuring technical consistency across distributed teams without direct management authority']

⚠️ Common Mistakes to Avoid

  • Presenting generic software architecture experience without specific examples from financial/trading systems or low-latency environments
  • Focusing only on management experience when this role requires technical influence without authority—they want a hands-on technical leader
  • Claiming C++ or quantitative expertise without being able to discuss specific algorithmic optimizations or pricing model audits in detail
