Junior Developer information

What is a junior developer?

A Junior Developer is an entry-level software professional who assists in creating, testing, and maintaining software applications. They typically work under the supervision of more experienced developers, learning best practices and acquiring new technical skills on the job. Junior Developers are expected to write code, fix bugs, and contribute to project documentation while gradually gaining experience in software development processes. This role is ideal for recent graduates or individuals transitioning into the tech industry.

What are the key skills and qualifications needed to thrive as a junior developer, and why are they important?

To thrive as a Junior Developer, you need a solid understanding of programming fundamentals, basic knowledge of software development life cycles, and ideally a degree in computer science or a related field. Familiarity with coding languages like JavaScript, Python, or Java, as well as version control systems such as Git, is commonly expected. Strong problem-solving abilities, eagerness to learn, and effective communication help you integrate into teams and adapt to new challenges. These skills are crucial for producing quality code, collaborating with colleagues, and growing within the fast-paced tech environment.

What are some common challenges faced by junior developers during their first year, and how can they overcome them?

Junior Developers often face challenges such as adapting to new codebases, understanding company workflows, and bridging the gap between academic knowledge and real-world applications. It’s common to feel overwhelmed by unfamiliar technologies or debugging complex issues. Overcoming these challenges involves proactively seeking mentorship, participating in code reviews, and consistently asking questions to clarify concepts. Building strong communication skills and collaborating with more experienced team members can also accelerate the learning process and help you grow more confident in your role.

Job description

About Limina

Limina is the contextual data intelligence platform built for the AI era. Evolved from Private AI, the world's most accurate PII and PHI de-identification engine, Limina has expanded into a full platform play that governs sensitive data across the entire enterprise AI lifecycle: from classification and redaction through to agentic workflows, RAG pipelines, and real-time data security.

Brands like RBC,  Deepgram, and Boehringer Ingelheim already rely on our platform to build on, govern, and deploy AI against their most sensitive datasets. We've been recognized as a Gartner® Cool Vendor™ in Privacy and a World Economic Forum Technology Pioneer, and we’re backed by investors in Toronto, New York, Seattle, and San Francisco. 


What is the opportunity

As a Junior Software Developer at Limina, you'll join our engineering team building and maintaining the services that power our data privacy platform. This is a hands-on role where you'll work across a modern backend architecture, contributing to the systems our customers and internal teams depend on every day.

You'll be supported by an experienced team of backend engineers, and this role is designed to help you grow quickly. You'll get real ownership over features and fixes from day one, with plenty of guidance along the way.


What does the day to day look like?

Our platform is built from independently deployable services, including a web API layer and a configurable background processing system, along with shared code for data models, caching, and job handling. As a junior developer, you'll get exposure to the full lifecycle of a production service, from API design to background job orchestration to database changes.

Responsibilities include:

  • Building and maintaining API endpoints and the business logic behind them
  • Contributing to asynchronous and background processing solutions that help our systems scale
  • Participating in database design and management, including schema changes over time
  • Writing and maintaining tests across unit, integration, and performance levels
  • Supporting analytics and observability efforts so we can understand how our systems behave in production
  • Participating in our CI/CD workflows, from code review through deployment
  • Contributing to user facing documentation and guides as you learn the system, so the next person ramps up faster than you did
  • Working with senior engineers on authorization design and other architectural decisions
  • Collaborating with other teams across the company to help design solutions based on customer requests and feedback


Required skills

  • Solid foundation in Python
  • Understanding of REST API concepts and basic backend architecture
  • Familiarity with relational databases (SQL, schema design)
  • Some exposure to Git and collaborative development workflows
  • Comfortable reading and learning from an existing codebase and documentation
  • Strong problem solving instincts and a willingness to ask questions


Nice to have

  • Exposure to a Python web framework (such as FastAPI, Flask, or Django)
  • Familiarity with Docker and containerized development environments
  • Some experience with background job or queue systems
  • Familiarity with caching or session stores such as Redis
  • Exposure to an ORM or database migration tools
  • Understanding of authentication, authorization, or access control systems
  • Experience with cloud platforms such as AWS
  • Familiarity with project management tools such as Jira
