What is a full stack software engineer?

A full stack software engineer develops all aspects of a software application, from the user interface to the back-end database. As a full stack software engineer, your job duties include gathering customer requirements, writing the code to develop the application, and troubleshooting the application for any issues. The qualifications to pursue a career as a full stack software engineer include an associate or bachelor’s degree in computer science, software engineering, or a related field and proficiency in a variety of coding languages and frameworks.

What are the key skills and qualifications needed to thrive as a full stack software engineer, and why are they important?

To thrive as a Full Stack Software Engineer, you need strong proficiency in both front-end (e.g., HTML, CSS, JavaScript) and back-end (e.g., Node.js, Python, Java) development, typically supported by a relevant degree or equivalent experience. Familiarity with frameworks (like React or Angular), version control (such as Git), databases (SQL/NoSQL), and cloud platforms is essential, and certifications like AWS Certified Developer can be beneficial. Problem-solving ability, collaboration, and adaptability are vital soft skills that help engineers navigate complex projects and work effectively in teams. These skills ensure the ability to deliver robust, scalable, and user-friendly applications that meet dynamic business needs.

How do full stack software engineers typically collaborate with other team members during a development project?

Full Stack Software Engineers often work closely with front-end and back-end developers, UI/UX designers, product managers, and QA testers throughout the software development lifecycle. Collaboration typically involves participating in agile ceremonies such as daily stand-ups, sprint planning, and code reviews to ensure alignment and progress. They are expected to communicate effectively across disciplines, help troubleshoot issues that span both client and server sides, and contribute to shared documentation. This collaborative environment helps ensure that solutions are cohesive, scalable, and meet user requirements.

What is the difference between Full Stack Software Engineer vs Front End Developer?

AspectFull Stack Software EngineerFront End Developer
Required SkillsProficiency in both front-end and back-end technologies, including HTML, CSS, JavaScript, server-side languages, and databases.Specializes in client-side technologies like HTML, CSS, JavaScript, and frameworks such as React or Angular.
Work EnvironmentWorks on both server and client-side development, often involved in full project lifecycle.Focuses primarily on designing and implementing user interfaces and user experience.
Common UsageUsed in full-stack development teams, startups, and projects requiring versatile developers.Found in teams emphasizing UI/UX, web design, and front-end frameworks.

While both roles require strong JavaScript skills, Full Stack Software Engineers handle both front-end and back-end development, whereas Front End Developers focus solely on the user interface and experience. The choice depends on whether you prefer a broader development scope or specialization in UI design.

Are full stack software engineers in demand?

Full stack software engineers are in high demand due to their ability to work on both front-end and back-end development, making them valuable in many industries. Companies seek these professionals for their versatility, often requiring knowledge of frameworks, programming languages, and tools like JavaScript, Python, and cloud platforms. The demand is expected to grow as digital transformation continues across sectors.

Can I learn full stack software engineer in 3 months?

Becoming a full stack software engineer in three months is challenging, as it typically requires several months to years of consistent learning to gain proficiency in both front-end and back-end development, including skills in programming languages, frameworks, databases, and version control. Intensive bootcamps or self-study programs can accelerate learning, but practical experience and project work are essential for job readiness.

Job description

Description

At CSpring, we believe in the power of people and data to drive real-world impact. We're a purpose-driven consulting firm that helps organizations solve complex problems, gain insights, and achieve measurable results. Our clients span the public and private sectors, and our work - from data strategy and engineering to workforce transformation - improves lives across Indiana and beyond. We're seeking talented professionals who are collaborative, curious, and committed to making a difference.


Why You'll Love Working Here

  • Work that carries real weight. You'll be validating data pipelines that support a state Medicaid system - your attention to detail has a direct downstream effect on how healthcare information reaches the people who need it.
  • A team that takes quality seriously. CSpring has a culture of rigor and care. We don't ship sloppy work, and we hire people who feel the same way - you'll be surrounded by colleagues who hold the same standard.
  • Room to grow your craft. You'll work across a modern, meaningful stack - Informatica PowerCenter, Teradata, Azure DevOps, and Python automation - with the latitude to improve and automate the processes you own.
  • Collaboration without silos. Our teams work in tight Agile cycles with real communication between QA engineers, ETL developers, and business stakeholders. 
  • Purpose-driven clients. Our government and healthcare clients are doing work that matters to their communities. When you support their data infrastructure, you're part of that mission too.

What You'll Do

You'll own the quality of data as it moves through ETL pipelines in a state Medicaid environment - from reviewing requirements all the way through defect resolution, regression testing, and automation.

  • Review Change Requests (CRs) and participate in requirement analysis for new EDW extracts and transformations.
  • Participate in data modeling and requirement gathering sessions to ensure testing stays aligned with business needs.
  • Perform backend testing to compare data in source systems to target Medicaid Enterprise Data Warehouses (EDW); verify source-to-target data mapping and transformation logic for Medicaid datasets.
  • Validate data quality, standardization rules, and loading accuracy across full-load and incremental-load cycles.
  • Write complex SQL queries - multi-table JOINs, aggregations, row counts, null checks, duplicate checks, and referential integrity validation - to validate ETL outputs against business rules.
  • Design test plans, test cases, and test scenarios for ETL processes; execute both manual and automated tests.
  • Identify, document, and track discrepancies using JIRA, HP ALM, or Azure DevOps Test Plans; collaborate with ETL developers to resolve defects and perform regression testing.
  • Develop automated database validation scripts using Python, SQLAlchemy, and Pandas; create shell scripts for ETL monitoring and log analysis.
  • Integrate test automation into CI/CD pipelines in Azure DevOps.
  • Document test results and provide detailed, actionable feedback to stakeholders.

Requirements

  • 5+ years of experience in software testing and quality assurance
  • 5+ years of experience testing backend, database, EDW, or ETL systems
  • 4+ years of strong SQL experience and hands-on work with at least one RDBMS (Teradata, SQL Server, Oracle, or similar)
  • 4+ years of experience in UI, smoke, end-to-end, and integration testing
  • 4+ years of experience in test design and working with at least one test management tool (Azure DevOps, JIRA, HP ALM)
  • Strong understanding of EDW and ETL concepts, including Star/Snowflake schema and Slowly Changing Dimensions (SCD1/SCD2)
  • Direct experience in a Medicaid, healthcare, or government data environment, including familiarity with HIPAA and healthcare data standards (837/835 claims, ICD-9/10, CPT, HL7)
  • Bachelor's degree in Computer Science, Information Technology, Data Analytics, Mathematics, or a related field

Preferred Qualifications

  • Hands-on experience with Informatica PowerCenter
  • Knowledge of Medicaid reporting, encounter data, and data mart validation
  • Familiarity with Medicaid Enterprise Systems (MES) or a state Medicaid agency (e.g., Illinois HFS)
  • Python test automation and GitHub for code management
  • Experience integrating automated tests into CI/CD pipelines

At CSpring, we unlock the potential of people and data. If you're ready to lead meaningful work, collaborate with passionate teams, and grow your career in a people-first consulting environment - apply today!
