Job Description

About CJ Engineering 

Are we a good match for you? 

At CJ, we are passionate about software engineering. We build exciting software, with quality and maintainability in mind. We believe in common sense, simplicity, and efficiency. We practice critical thinking, challenge each other no matter the title, and believe in the wisdom of the team. 

That makes us Engineers and not just developers. Here are some of the principles that set CJ engineers apart.  

• Engineering autonomy: Here, business decisions are made by business people, and technical decisions are made by technical people. 
• Full stack: Expect to be involved and to gain competence in every aspect of software engineering, from frontend, to database, to requirements analysis, to testing, to helping choose technologies. 
• Clean, Maintainable code: Code is read more often than it is written, so we put in the effort to write it well in the first place. 
• Pairing: The highest quality code is produced by close collaboration, so we pair by default. 
• TDD: Quality is baked into our process through Test Driven Development 
• Ownership: Engineers own the full lifecycle of what they build-from design and implementation to deployment, monitoring, production support, and on-call rotations. If we build it, we support it. 
• Operational Excellence: We embrace Infrastructure as Code, CI/CD, automation, and observability to build reliable systems and deliver software safely, efficiently, and at scale. 
• We believe in Agile values, and incremental development. We constantly experiment, retrospect, and adjust. 
• We are committed to finding out how AI can amplify our productivity. We view AI as a force multiplier, not a replacement for good engineering.
