As a Software Engineer at Charlotte Staffing, your day-to-day work will involve a dynamic mix of software development, system integration, and collaborative problem-solving. You will be embedded within an Agile team, working closely with product owners, designers, and security professionals to deliver high-quality, working software.

Your primary focus will be designing and implementing scalable backend services and automated data pipelines. This includes writing clean, well-tested code in languages like Python, Go, or Java, and building out automated unit, integration, and performance testing frameworks. You will also be responsible for maintaining continuous integration and continuous deployment (CI/CD) pipelines, ensuring that security controls and monitoring capabilities are built directly into your delivery process.

In addition to technical execution, you will play an active role in refining user stories, conducting spike investigations, and performing proof-of-concept evaluations to mitigate technical risk. As you grow in the role, you will have opportunities to lead moderately complex projects, mentor junior teammates, and contribute directly to the architectural strategy of our platform services.

We look for candidates who possess a strong foundation in computer science, practical software engineering experience, and a collaborative mindset. The competitive candidate profile typically includes:

• Must-have skills – Strong proficiency in Python, Go, or Java; experience building RESTful APIs; familiarity with database technologies (SQL and NoSQL); hands-on experience with version control (Git) and CI/CD tools.
• Nice-to-have skills – Experience with containerization (Docker, Kubernetes); knowledge of cloud-native infrastructure (Terraform, AWS); familiarity with AI/ML frameworks (LangChain, vector databases); and experience with growth experiments or A/B testing.
• Experience level – Typically requires a Bachelor's degree in Computer Science or a related field, combined with 4 to 8+ years of professional software engineering experience (or equivalent practical training).
• Soft skills – Excellent written and verbal communication; strong analytical thinking; ability to work independently in an ambiguous environment; and a collaborative, approachable attitude.

Q: What is the typical interview preparation timeline for this role? Most successful candidates dedicate 2 to 4 weeks to prepare. This allows sufficient time to practice coding challenges, review system design concepts, and structure behavioral examples using the STAR method.
