Role Description As a Spring Boot Software Engineer , you will be working with our team to create and maintain web applications that our clients use to interact with our machine learning solutions and data platforms. Throughout the engagement, your goal will be to deliver reliable, maintainable, and high-quality solutions that create meaningful value for our clients. You will be involved in designing, developing, and maintaining both frontend and backend components . While this role has a strong emphasis on Spring Boot development and maintenance , you should be comfortable working across the application stack to support client solutions . You must be comfortable working with APIs — expect to build applications that consume both internal and external APIs. Throughout the engagement, you may work on: - Building new features - Maintaining existing applications - Enhancing system capabilities - Resolving production issues - Improving the reliability and performance of established systems Across the board, you are expected to have great code hygiene. Readable, documented code is at the core of our collaborative projects. Even better if you are already routinely testing your code. Finally, it is very important that you are comfortable using version control systems (ideally git) and contributing to codebases that are actively maintained by multiple engineers. This opportunity is offered as a fixed-term contract engagement. Qualifications - Has 3+ years of hands-on experience developing and maintaining applications using Spring Boot. - Is a strong independent contributor who can take ownership of work, navigate ambiguity, and deliver with minimal supervision. - Has experience developing and maintaining both frontend and backend components of web applications. - Enjoys coding and has great code hygiene: You must be very comfortable with writing and explaining code. In addition, you must be able to write clean, clear, and maintainable code as you are not the only one who will read and work on your code. - Has demonstrated experience working with: - Spring Boot - some or all of our usual tech stack (i.e., Python, JavaScript, React, Django, Flask, FastAPI, Airflow, Dagster) - any SQL/NoSQL databases (e.g., PostgreSQL, Elasticsearch) - cloud computing platforms (e.g., AWS, GCP, or Azure) - APIs and system integrations - git - Has strong communication skills: You'll be explaining things during most conversations either internally or externally, and with both technical and non-technical audiences. Therefore, you need to know how to communicate clearly depending on who you're talking to. Documenting your code is a given, and you should be comfortable writing technical documentation when needed. - Makes things fast: Time is our most precious resource. You can always throw money at things to make them faster, but that's not very engineer-y. - Builds sustainably: It's okay to labor over a new thing once or twice, but if we have to do it a third time, we need to think about how to scale it with less effort. Suggest best practices, create reusable patterns, and contribute to maintainable solutions. - Has high initiative: Sometimes, the team won't know that they need you. You need to be aware of the projects people are working on, proactively identify issues and opportunities, and support the team when applicable. Engagement Terms - Competitive professional fee — the fee amount is positively correlated with the difficulty of the job, relevant experience, fit, and skill factors. - Remote Set-Up — fully remote, with a strong emphasis on ownership, asynchronous collaboration, and output-driven work. - Opportunity to collaborate closely with our engineers and subject matter experts throughout the engagement.
