Junior Software Engineer (SWE)

Every single modern software engineer needs these basic skills to be IT career/job/work-ready:

Linux cmd (command line) basics for directory navigation (cd), listing files (ls), cat, vi, rm, mkdir, ssh (for secure FTP), etc. which has carryover in all environments; UNIX console commands, Linux bash/shell, Mac iTerm/terminal
Some exposure to Adobe Photoshop for simple icon editing, transparency/png/webp graphics manipulation
Java fundamentals which can translate to JavaScript functional programming for modern web/native development (React/Angular/Vue), or classical Java/Spring Boot
SQL (structured query language) is an absolute must for basic table joins on data retrievals, updates, or deletes (these skills will translate easily between dev stacks using MySQL, MS-SQL Server, Oracle or PostgreSQL)
Python scripting is also functional for machine learning (ML) and will also be helpful for PySpark (Apache Spark) and data lakehouses
Scala/Spark SQL for the manipulation of Hadoop data lakes, Kafka message queues & real-time streaming data pipelines
Go scripts for microservices & serverless
GraphQL query experience for data visualizations
Terraform (HashiCorp), AWS CloudFormation, Ansible (Red Hat) YAML config files for "cloud provisioning" or Infrastructure as Code (IaC) are becoming a must to advance to Intermediate/Senior

How do I advance beyond Jr. to more Sr. & Intermediate roles?

You'll need to work well with the product designers, marketing teams or internal users to understand what client requirements are important to build in to your product(s). Depending on the setup of your company, it usually happens in two (2) ways; A) product/marketing is your business user (as they have gathered user-generated requests for you) or; B) your business is bigger and you'll have internal clients where IT & marketing will sit in the same meetings with internal users of your products. We see a path of a junior SWE to senior by either transitioning to pre-sales advocacy (tech evangelism) of your products which will include hiring new developers as a principle SWE (software engineer) of sorts, or taking the operations path and becoming an expert in DevOps, code pipelines with CI/CD such as Jenkins, Chef, Puppet, etc. and managing cloud software containers on-prem, or in one of the many platforms AWS, Azure, GCP, IBM Cloud, Oracle, etc. that we call "big cloud". This could also include managing agile/Scrum teams, systems design & database administration, setup of hardware/specs/systems for developers, doing product releases, mentoring other dev/team members.
