Junior Back End Developer information
What is a junior back end developer?
A Junior Back End Developer is an entry-level software developer responsible for building and maintaining the server-side logic, databases, and APIs of web applications. They work with programming languages like Python, Java, or Node.js and collaborate with front-end developers to ensure seamless integration. Their tasks often include writing code, debugging issues, optimizing performance, and managing databases. Juniors typically work under the guidance of senior developers to improve their skills and gain experience in back-end development.
What are some common challenges faced by junior back end developers in their first role?
Junior Back End Developers often find themselves adjusting to complex codebases and learning how to troubleshoot issues within existing systems. Navigating unfamiliar frameworks, understanding best practices for security and performance, and collaborating effectively with front-end developers and other team members can also be initial challenges. Many juniors spend time improving code review skills and learning to communicate technical issues clearly. Embracing these learning opportunities and seeking mentorship will help you grow quickly and build confidence in your new role.
What are the key skills and qualifications needed to thrive in the junior back end developer position, and why are they important?

With many exciting projects underway, we're driven to generate the next billion-dollar business-so if you're passionate about tackling bold challenges, join us!
We are a close-knit group of engineers of different stripes - developers, designers, and product owners - who are working together to solve interesting e-commerce and supply chain problems around how people eat. Sometimes, this involves implementing features to improve the user
journey and making it easier for our customers to buy amazing food. Other times, this means creating stable software solutions that keep our distribution centers running.

- All other duties, as assigned
Sound a-peeling? Here's what we're looking for
- Hands-on experience working with AI tooling (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents every day. You have a practical sense of how the context you provide to AI tools shapes output quality, and how to set boundaries on AI-generated work.
- Experience: Experience in software engineering, with a strong focus on back-end development and system architecture.
- Technical Skills: Proficiency in back-end technologies and programming languages (e.g., Python, SQL, Go) and a deep understanding of distributed systems and microservices architecture.

- Agile Methodologies: Solid experience in Agile development practices, with an ability to adapt to changing priorities and deliver high-quality results on time.
- Mentorship Skills: Strong mentorship abilities, with a passion for guiding and developing junior engineers while fostering a collaborative team culture.
- Analytical Mindset: Excellent analytical and troubleshooting skills, with a proactive approach to identifying and resolving technical challenges.
- Communication Skills: Effective verbal and written communication skills, capable of articulating complex technical concepts to diverse audiences and collaborating effectively with cross-functional teams.
- You take full ownership. You have a bias to ship. You finish the last twenty percent.
- You have product sense and are opinionated about what should be built and why, and you can back that opinion with data and user evidence.
