About the Role
As a Software Engineer I on the Martech Intelligence Pod, you'll be starting your engineering career working on real customer-facing applications across both frontend and backend, learning the foundations of professional software development in a supportive environment. You'll also have the opportunity to explore and learn about AI tools and AI-centric solutions that are becoming central to how we build products.
Your primary focus will be maintaining and improving the customer-facing websites we host while gradually learning about infrastructure and integration challenges the Intelligence Pod tackles. Importantly, you'll also have dedicated time to explore AI tools, experiment with LLM APIs, understand how agents work, and think about where AI can solve problems better than traditional approaches.
This is a structured onboarding role: you'll work closely with senior engineers who will mentor you through the full development lifecycle — from understanding requirements, to writing frontend components and backend services, to testing, debugging, and deploying to production. You'll start with well-scoped, low-risk tasks on both frontend and backend, and gradually take on more responsibility as you gain confidence and expertise. You'll also spend time experimenting with AI tools, building small proof-of-concepts, and learning how modern AI capabilities can be integrated into applications.
The role demands intellectual curiosity, a willingness to ask questions, and genuine interest in learning how real systems work — both traditional software and AI-powered systems. Success is measured by your growth as a full-stack engineer, the quality of code you write, your reliability, your ability to communicate what you're learning, and your engagement with exploring AI as a tool and mindset. This is a fully-supported entry point into professional full-stack software engineering at a global scale, with exposure to cutting-edge AI capabilities.
Who You Are
We're optimizing for learning potential, solid fundamentals, and genuine engagement with engineering. You don't need years of experience — you need to be curious, humble about what you don't know, and eager to grow.
You have a Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent bootcamp/self-taught experience with a portfolio demonstrating competency
You are proficient in English, both written and verbal, sufficient for success in a remote and largely asynchronous work environment
You have 0-2 years of professional software engineering experience, or are a recent graduate with solid foundational knowledge
You have hands-on experience writing code in C# or Java (through academic projects, bootcamp, or personal projects) and understand the basics of how programs work
You have some experience with React and TypeScript or are eager to learn them quickly — through academic projects, bootcamp, tutorials, or personal projects; you understand the basics of components and JSX
You know the basics of HTML, CSS, and JavaScript — you understand how the browser works and can build simple web pages and interactive elements
You understand the fundamentals of object-oriented programming: classes, objects, inheritance, and interfaces
You can debug code in multiple environments: backend (logs, IDE debugger) and frontend (browser developer tools, console logs)
You've written code that other people have read and reviewed — you're comfortable receiving feedback and iterating
You know the basics of relational databases and can write simple SQL queries (SELECT, INSERT, UPDATE); you're learning to think about data
You've worked with Git and understand the basics of version control, branching, and merging
You can debug code systematically: read error messages, add logging, trace through code, form hypotheses about what's wrong
You're genuinely curious about how things work and you ask good questions when you don't understand something
You're interested in and curious about AI tools (LLMs, generative AI, agents) — you've probably experimented with ChatGPT, Claude, or similar tools and think about how they could be useful
You're open to exploring AI-centric solutions to problems and willing to experiment with new approaches that leverage AI capabilities
You can explain what you've learned in writing: you're comfortable documenting decisions, asking for help in PRs, and sharing what you discovered
You're reliable and follow through: you finish what you start, communicate when you're blocked, and ask for help before getting stuck for too long
You're humble about what you don't know and genuinely want to learn from more experienced engineers
You make an effort to include others and appreciate feedback as a gift, not a criticism
What You'll Do
Learning & Foundational Work:
Work on small, well-scoped tasks with clear acceptance criteria: bug fixes, simple feature additions, documentation improvements (both frontend and backend)
Get hands-on with the tools and technologies we use: C#/Java backend, React/TypeScript frontend, SQL, Git, our test frameworks, our deployment processes
Learn how our customer-facing applications work: what AEM is, how WordPress sites are structured, how they serve customers, how frontend and backend work together
Understand the full development lifecycle: from understanding a requirement, to writing code (frontend components and backend services), to testing, to deploying to production with safety
Frontend Development:
Fix simple bugs in our React/TypeScript applications: layout issues, component state problems, missing features
Implement small features: simple forms, content displays, UI improvements requested by stakeholders
Learn React fundamentals: components, hooks, props, state management
Debug frontend issues using browser developer tools: understand CSS problems, trace JavaScript execution
Help improve frontend test coverage: write simple unit tests for components
Learn how to consume backend APIs from the frontend: understand requests, responses, error handling
Backend Development:
Help fix bugs in our C# or Java backend services: simple issues with clear reproduction steps
Implement small backend features: API endpoints, database queries, business logic
