Interns are usually paired with a mentor and integrated into agile teams, where they are encouraged to take ownership of their assigned tasks and present their solutions. While guidance and code reviews are standard, interns are trusted to design, implement, and test their code, allowing for meaningful hands-on experience and a direct impact on product outcomes.

What does a software development engineer intern do?

A Software Development Engineer Intern assists in designing, coding, testing, and maintaining software applications under the guidance of experienced engineers. Interns typically work on real projects, write code, debug issues, and collaborate with team members to learn the software development lifecycle. This role helps interns gain practical experience, improve programming skills, and understand how software teams operate in a professional environment.

Magnet Forensics is a global leader in the development of digital investigative software that acquires, analyzes, and shares evidence from computers, smartphones, tablets, and IoT-related devices. We are continually innovating so our customers can deploy advanced and effective tools to protect their companies, communities, and countries.
 
Serving thousands of customers globally, our solutions are playing a crucial role in modernizing digital investigations, helping investigators fight crime, protect assets, and guard national security.
 
With employees based around the world, Magnet Forensics has been expanding our global presence. As a part of Magnet Forensics, you can expect to make a difference in the world, no matter what role you play. You'll be supported through learning and development, not to mention an incredible team with unbelievable talent and integrity.
 
If you think you would be the right person to join our team working towards this goal, we would love to hear from you! 

Role Overview 

We are seeking a highly skilled and experienced Senior Software Development Engineer in Test (SDET) to join our engineering team, supporting the development and deployment of our next-generation AI-powered products. In this role, you will architect, build, and maintain production-grade test infrastructure and automation frameworks to ensure the reliability and performance of our cloud platform. You will write high-quality, maintainable code for testing tools, CI/CD pipelines, and validation systems that serve as critical engineering infrastructure. You will work closely with developers, product managers, and other SDETs to design and implement robust cloud test strategies, automation frameworks, and validation tools.

The successful candidate will flourish making meaningful contributions and elegant solutions, be determined, and manage major turning points independently in a fast-paced environment. You'll approach test automation as a software engineering discipline, applying the same rigor to test code that you would to production code, treating test infrastructure as a product that serves internal customers (developers) with the same care as customer-facing features.

What You'll Do

  • Architect and build reusable test frameworks and libraries that serve as shared infrastructure across teams;

  • Design and implement testing SDKs and tools that enable other engineers to write better tests faster;

  • Contribute to the product codebase by improving testability, instrumentation, and observability;

  • Conduct code reviews for test automation pull requests, ensuring best practices and maintainability;

  • Apply software engineering principles (design patterns, SOLID) to test automation architecture;

  • Define and maintain an automation roadmap aligned with team goals and product evolution;

  • Act as a subject matter expert in test strategy and tooling within your domain;

  • Mentor and coach other SDETs or SWEs on Quality Engineering best practices;

  • Engineer end-to-end CI/CD pipelines including build orchestration, deployment automation, and infrastructure-as-code for test environments;

  • Validate deployments across multiple cloud environments;

  • Work closely with development to improve the quality of the product.

What We're Looking For

  • 5+ years of experience in Software Development in the Quality Engineering field with a strong focus on cloud automation;

  • Strong software engineering skills with demonstrated proficiency in at least one programming language (e.g., Python, C#, Java), including:

    • Object-oriented design and design patterns

    • Writing clean, maintainable, well-documented code

    • Version control (Git) and code review practices

    • Software architecture and system design principles

  • Experience with or strong interest in AI-powered development workflows;

  • Experience building production-quality automation frameworks, testing libraries, or developer tools from scratch;

  • Strong understanding of software architecture, APIs, SDKs, and system integration testing with hands-on experience designing and implementing APIs for test frameworks or validation tools;

  • Familiarity with CI/CD pipelines and cloud-based testing environments;

  • Excellent problem-solving skills and attention to detail;

  • Strong communication and collaboration skills.

Nice to Have Skills

  • Familiarity with testing LLM-powered applications and agentic systems;

  • Experience with infrastructure-as-code (CDK, Terraform, CloudFormation);

  • Familiarity with software design patterns and refactoring techniques;

  • Background in distributed systems or cloud architecture;

  • Knowledge of observability patterns (structured logging, distributed tracing, metrics instrumentation);

  • Familiarity with monitoring and alerting tools (e.g., Grafana, DataDog, CloudWatch);

  • Experience with BDD, contract testing (Pact);

  • Familiarity with AWS: S3, DynamoDB, OpenSearch;

  • Exposure to security testing, performance testing, and regression strategies;

  • Knowledge of Docker containers.

Indicators of Success
 
We're looking for someone who checks off most, but not all, of the boxes listed in "skills and experiences".  It's more important to us to find candidates who can display indicators of success through skills they have developed and experiences they have been a part of, than to find folks who have "been there, done that".  We want to be part of your development journey, and we'll learn as much from you as you learn from us. 
 
How We Work
 
At Magnet Forensics, we take a hybrid-flexible approach to support your productivity and work-life balance. If you're within a comfortable travel distance to one of our offices, you'll occasionally join us in person. How often you'll come in depends on your department and team needs, typically ranging from weekly to monthly. These in-person moments help us build stronger connections, spark new ideas, and celebrate our successes together. Most days, you can choose what works best for you, while staying in tune with your team's goals.
 
We're excited to welcome you to our team and look forward to achieving great things together - both in the office and wherever you work best!
 
The Most Important Thing
 
We're looking for candidates that can provide examples of how they have demonstrated Magnet CODE in their previous experiences:
 
CARE - We care about each other and our mission to make a difference in the world.
OWN - We are accountable for our results - while never forgetting to act with integrity, empathy, and respect.
DEDICATE - We put our heart and soul into meeting the needs of our customers and helping them serve the people they protect.
EVOLVE - We are constantly innovating and exploring new ways to work together to make an impact with our work.
 
Here at Magnet Forensics, we are committed to continuous learning and are focused on building a diverse and inclusive workforce. This commitment will be reflected in our hiring processes and embedded in our values and how we treat one another. If you're interested in this role, but do not meet all of the qualifications listed above, we encourage you to apply anyways.

We are committed to providing an inclusive, accessible recruitment process and work environment. Accommodation is available to all applicants upon request throughout the hiring process.
