As a Software Engineer, your day-to-day work centers on the full development lifecycle. You will be responsible for writing high-quality code, conducting code reviews, and collaborating with your peers to ensure that system architecture remains scalable and secure. You will often act as a bridge between technical requirements and business outcomes, ensuring that the software you build directly serves the needs of the organization.

Collaboration is a cornerstone of this role. You will work closely with other engineers and potentially operations teams to deploy features and troubleshoot issues. Whether you are building new modules for internal tools or maintaining existing infrastructure, your focus will be on delivering reliable, performant solutions that support the company's broader objectives in the energy market.

• Nice-to-have skills: Experience with cloud-based hosting environments and familiarity with security best practices in enterprise applications.
• Experience level: Mid-level experience is typically preferred, though the ability to demonstrate clear logical reasoning during technical assessments is often weighed as heavily as years of experience.
