Mastering these skills ensures you can contribute to data-driven projects and grow into more advanced roles in the field.

What is a Data Science Apprentice?

A Data Science Apprentice is an entry-level professional who is learning the skills required to become a data scientist, often through a structured apprenticeship program. They work under the guidance of experienced data scientists to gain hands-on experience in analyzing data, building models, and using data science tools and techniques. Apprenticeships typically combine on-the-job training with classroom instruction, allowing apprentices to develop both practical and theoretical knowledge. The goal is to prepare apprentices for a full-time role in data science by the end of the program.

How do Data Science Apprentices typically collaborate with senior data scientists and other departments?

As a Data Science Apprentice, you'll often work closely with senior data scientists through mentorship and project-based tasks. Collaboration usually involves assisting with data cleaning, exploratory analysis, and supporting model development under supervision. You'll also interact with team members from engineering, product, or business departments to understand project goals and present findings. This cross-functional teamwork helps you build both technical and communication skills, preparing you for more independent roles in the future.

Responsibilities
  • Design, build, test, and release our web-based operational dashboards, electronic procedure tools, and a suite of specialized software solutions to support various space missions
  • Create software to support simple and complex computation on datasets for decision-making and autonomous execution
  • Build and deploy high-quality code on a daily basis for rapid iteration and testing with users
  • Design APIs and integration solutions for various proprietary and open-source telemetry and command and control systems
  • Rapidly prototype demos and proof-of-concepts for customer meetings
  • Join and actively participate in customer discovery calls and technical demonstrations
  • Analyze and enhance the efficiency, stability, and scalability of software systems
  • Support software QA and user testing
  • Assess third-party and open-source software and develop integrations

Qualifications
  • 3+ years of experience as a Software Engineer
  • Proficiency with TypeScript and with JavaScript frameworks like React, Vue, Angular, or Svelte
  • Strong foundation in computer science concepts (algorithms, data structures, object-oriented programming, design, testing, etc.)
  • Self-starter and able to navigate ambiguity and assess rapidly evolving priorities
  • Strong team player with great communication skills and collaborative work ethic
  • Love of learning (technical and otherwise)
  • Experience at fast-growing tech startups is a plus
  • Experience with Lean Startup & Agile software development methodologies is a plus
