Junior Software Programmer information

What is a junior software programmer?

A Junior Software Programmer is an entry-level professional responsible for writing, testing, and maintaining code under the guidance of more experienced developers. They typically work on specific tasks or small projects, learning industry practices and programming languages on the job. Junior programmers often collaborate with other team members to develop software solutions and resolve bugs, gaining experience as they grow into more advanced roles.

What are the key skills and qualifications needed to thrive as a junior software programmer?

To thrive as a Junior Software Programmer, you need a solid understanding of programming fundamentals, typically demonstrated by a degree in computer science or related field and experience with languages like Python, Java, or C++. Familiarity with version control systems (such as Git), basic debugging tools, and integrated development environments (IDEs) is also important. Strong problem-solving abilities, attention to detail, and effective communication are essential soft skills that help you learn quickly and collaborate with team members. These skills ensure you can contribute to codebases efficiently, adapt to new technologies, and support team goals in a fast-evolving technical environment.

What are some common challenges a junior software programmer might face during their first year on the job?

In their first year, Junior Software Programmers often encounter challenges such as adapting to new codebases, understanding development workflows, and balancing learning with productivity. They may also find it difficult to communicate technical issues clearly to team members or to estimate how long a task will take. However, most teams provide mentorship and regular feedback to help new programmers grow and integrate smoothly with the team’s processes.

What is the difference between Junior Software Programmer vs Junior Web Developer?

AspectJunior Software ProgrammerJunior Web Developer
Required SkillsProgramming languages (e.g., Java, C++, Python), software development fundamentalsHTML, CSS, JavaScript, basic backend knowledge
Work EnvironmentSoftware companies, tech firms, development teamsWeb agencies, tech startups, freelance projects
Common UsageDeveloping software applications, system toolsBuilding websites, web applications

Junior Software Programmers focus on developing software applications and systems using programming languages, often working in software or tech companies. Junior Web Developers specialize in creating websites and web-based applications, typically working in web agencies or startups. While both roles require basic coding skills, their focus areas and tools differ, making each suitable for different career paths within the tech industry.

Job description

Join our Framework team: the engineering foundation that makes Achievers scale.  

This team owns authentication, API gateways, interservice communication, caching, feature flag management, and the base libraries that every Go and Python service at Achievers is built on - all sitting at the critical path of everything we ship. 

 Your work here has a multiplier effect.  

The libraries, platforms, and tooling you build are used by roughly 100 engineers across the company.  

When you raise the floor - better DX, faster onboarding, more consistent patterns, AI-first tooling - the whole engineering organization moves faster.

Please note that this is a back-end focused role. Successful candidates will be able to bring a strong backend engineering background and be excited about continuing to deepen their expertise in backend and platform development. At this time, this role is not intended as a transition role for engineers whose primary experience and career interests are front-end-focused.

Why you'll love this role:

What makes this team unique is the breadth of its perspective.  

  • Framework is the one team that holds end-to-end understanding of how base libraries must interact with the infrastructure layer and the CI/CD pipeline.
  • That bird's-eye view of the platform means this team is where platform-wide challenges land - and where the solutions that unblock everyone else originate. 

Right now, the team is in the middle of some of the most technically interesting work in the company: modernizing our authentication and API gateway architecture. 

  • These are high-stakes architectural shifts that require both deep technical judgement and the ability to drive alignment across teams.
  • If you're energized by building for builders - designing systems that are secure, highly available, and genuinely pleasant to work with - and you want your architectural decisions to have company-wide reach, this is the team. 
How you'll shape our software engineering practices:
  • Provide guidance and mentorship to a team of software developers with varying experience levels, fostering an environment of continuous learning and improvement.
  • Design, build, and maintain innovative product features that enhance the Achievers platform.
  • Work closely with product managers, designers, and other engineering teams to define requirements and translate them into technical solutions. Actively participate in cross-functional planning sessions to align on priorities and dependencies.
  • Be hands-on with the codebase, actively engaging in code reviews and ensuring best practices are followed.
  • Utilize a wide range of modern tools and technologies, including Python, Go, Kubernetes, Docker, Drone, Google PubSub, GraphQL, MySQL, PostgreSQL, and Microservices, to solve complex challenges.
  • Architect high-performance, highly available, and secure software solutions that scale to millions of users.
  • Ship code regularly-multiple times a day, enabling continuous improvement and rapid delivery of new features.
  • Take full ownership of features or modules from design through deployment, ensuring the quality and reliability of the codebase.
  • Monitor application performance and optimize code to ensure it meets scaling, performance, and security requirements as the product grows.
  • Contribute to and enforce engineering best practices, standards, and guidelines for coding, testing, and infrastructure across the team. Lead and initiate engineering improvements, whether it's through tooling, processes, or adopting new technologies, to ensure the team is working effectively.
  • Ensure that systems, designs, and decisions are well-documented, making it easier for other engineers to understand, maintain, and expand upon your work.
  • Continuously learn and stay up-to-date with industry trends, emerging technologies, and software engineering practices to bring fresh perspectives and ideas to the team.
  • Guide junior engineers not only on technical solutions but also on career development, helping them set goals, identify growth areas, and improve their soft skills.
Experience we feel will set you up for success:
  • 8+ years of relevant back-end software development experience leading projects and especially system design, with at least 3 of them in a Senior/Staff capacity. 
  • Excellent written and verbal communication skills
  • Strong programming skills in Python or Go are highly advantageous. 
  • Comfortable working in a UNIX/Linux environment
  • Experience with Docker and Kubernetes.
  • Strong understanding of microservices architecture.
  • Experience with distributed systems.
  • Experience with API gateway design, gRPC, and service-to-service communication patterns
  • Experience designing authentication and authorization systems (OAuth2, OIDC, PKCE, JWT)
  • Ability to analyze business requirements and create technical design documents aligned with architecture standards
  • Passion for performance profiling and benchmarking. 
  • Experience executing large-scale migrations with zero downtime in production systems
  • Track record of building shared libraries or SDKs used across large engineering organizations
  • Bachelor's or Master's degree in Computer Science or a related field
  • Experience working in Agile teams
