How to apply for Senior Engineer

About ICAP Energy AS

ICAP Energy AS is a leader in driving sustainable markets through innovative energy and commodities brokering. Their focus on sustainability and cutting-edge technology makes them a unique place to work for engineers passionate about green finance and global impact.

About the role

As a Senior Engineer, you will design and build scalable software solutions that power the company's trading platforms. Your work will directly influence market efficiency and client success, with ownership of features from concept to delivery.

A typical day

You'll start by reviewing code from junior engineers, then dive into designing a new feature for the trading platform. After a stand-up, you might debug a client's API integration issue, then spend the afternoon coding and testing a database optimization. The day ends with a mentoring session and planning for the next sprint.

Who ICAP Energy AS is looking for

• Proven expertise in C#, Java, or C++ with a track record of delivering production-grade systems.
• Strong Unix/Linux and Windows development skills, including cross-platform deployment.
• Experience with both relational (Oracle) and non-relational (MongoDB) databases in high-performance contexts.
• Excellent communication skills to mentor juniors and support external clients using proprietary APIs.

Tips for this application

• Highlight any experience with financial or trading systems, especially real-time data processing.
• Showcase cross-platform development projects (Linux + Windows) in your resume or portfolio.
• Demonstrate API design and client support experience, as this role involves external client interaction.
• Use keywords from the job description (e.g., scalable, mentor, proprietary API) in your resume.
• Tailor your cover letter to mention ICAP's sustainable market focus and how your skills align.

What to cover in your cover letter

['Your ability to own features end-to-end and deliver high-quality outcomes.', 'Experience mentoring junior engineers and fostering technical excellence.', 'Proficiency with the specific tech stack (C#/Java/C++, Unix/Linux, Oracle/MongoDB).', 'Interest in sustainable energy markets and how your work contributes to that mission.']

Research before applying

• ICAP Energy's role in sustainable energy markets and key clients.
• Their proprietary trading platforms and any public API documentation.
• Recent news about ICAP's technology initiatives or partnerships.
• The company's engineering culture and any blog posts about their tech stack.

Likely interview topics

Based on the job description, expect questions about:

• Design a scalable system for real-time energy trading data.
• How do you optimize database queries for both Oracle and MongoDB?
• Describe a time you mentored a junior engineer and improved their performance.
• Explain how you would handle a client struggling with your API integration.
• Walk us through a cross-platform deployment challenge you solved.

Common mistakes to avoid

• Failing to mention cross-platform experience when it's explicitly required.
• Overlooking the client-facing aspect of the role (API support) in your application.
• Not demonstrating ownership of features or lack of concrete examples of end-to-end delivery.
