Typescript React Developer Junior information

What is a Typescript React developer junior?

Typescript React Developer Juniors are entry-level software developers who specialize in building web applications using React, a popular JavaScript library for user interfaces, and TypeScript, a typed superset of JavaScript. They typically have foundational knowledge of these technologies and work on tasks such as developing components, fixing bugs, and collaborating with more experienced developers. Junior developers are expected to learn best practices, write clean and maintainable code, and gradually take on more complex responsibilities as they gain experience.

What are the key skills and qualifications needed to thrive as a junior Typescript React developer?

To thrive as a Junior TypeScript React Developer, you need a solid understanding of JavaScript, TypeScript, React fundamentals, and basic web development principles, often supported by a relevant degree or coding bootcamp experience. Familiarity with version control systems like Git, package managers (npm/yarn), and front-end build tools is typically required. Strong problem-solving skills, attention to detail, and effective communication help you collaborate and learn within development teams. These skills and qualities are crucial for building reliable, maintainable user interfaces and for growing professionally in a fast-paced tech environment.

What are some common challenges junior Typescript React developers face when joining a new team, and how can they overcome them?

Junior Typescript React developers often encounter challenges such as understanding established codebases, adapting to team coding standards, and effectively using TypeScript’s type system. To overcome these, it’s helpful to actively participate in code reviews, seek feedback from senior developers, and make use of available documentation. Regularly pairing with teammates and practicing writing typed components can also accelerate learning and ease the transition into collaborative workflows.

What is the difference between Typescript React Developer Junior vs Typescript React Developer Mid-Level?

CriteriaTypescript React Developer JuniorTypescript React Developer Mid-Level
Experience0-2 years2-5 years
SkillsBasic understanding of React and Typescript, limited project experienceProficient in React and Typescript, able to handle complex projects
ResponsibilitiesAssist in development, bug fixing, learning best practicesLead small features, optimize code, mentor juniors
Work EnvironmentEntry-level teams, supervised tasksCollaborative teams, independent task management

The main difference between a Typescript React Developer Junior and a Mid-Level is experience and responsibility. Juniors are typically new to the field, focusing on learning and assisting, while Mid-Level developers handle more complex tasks and contribute more independently.

Job description

We are looking for a product-focused AI Software Engineer to turn advances in AI into restaurant products that work reliably in the real world. You will build across customer-facing experiences, backend services, agent workflows, integrations, and evaluation systems. The job begins with a customer or product problem and ends when the solution is operating successfully in production-not when a model call works locally.

You may work on voice ordering, reservations, catering, restaurant operations, client configuration, analytics, or entirely new agent capabilities. You will collaborate directly with product, design, customer-facing teams, and restaurant operators; make fast product and technical tradeoffs; and own the quality of the resulting experience.

Our stack includes Python and FastAPI services, PostgreSQL, TypeScript, React and Next.js applications, real-time voice agents built with LiveKit, cloud infrastructure on AWS, and modern LLM, speech, and multimodal providers. Exact stack match is less important than full-stack range, product judgment, and a record of shipping.


What you'll own
  • Build and ship end-to-end AI product experiences from problem discovery and prototype through launch, measurement, and iteration.
  • Develop customer-facing interfaces, backend APIs, data models, agent tools, and integrations as one coherent product.
  • Design agent workflows that combine models, context, memory, business rules, deterministic services, and human escalation.
  • Work directly with restaurant and internal users to understand failures, uncover unmet needs, and convert feedback into reusable product capabilities.
  • Integrate with POS, reservation, messaging, telephony, and other external systems while handling imperfect data and real operational constraints.
  • Build evaluations, instrumentation, guardrails, and feedback loops so probabilistic behavior can be measured and improved.
  • Improve latency, reliability, accuracy, usability, and cost across the full experience-not only within one layer of the stack.
  • Use AI-native development workflows to prototype and deliver quickly while retaining ownership of architecture, tests, security, and correctness.
  • Participate in product and technical planning, make tradeoffs explicit, and drive decisions when the path is ambiguous.
  • Raise the quality of nearby systems through code review, documentation, design discussion, and pragmatic refactoring.

Requirements

  • 3+ years of industrial experience in relevant technical domain.
  • Strong software engineering fundamentals and experience shipping production web or platform products.
  • Depth in either Python/backend engineering or TypeScript/React frontend engineering, plus the ability and desire to work effectively across the full stack.
  • Experience building with LLMs, speech models, computer vision, or agent systems beyond a toy prototype.
  • Product judgment: you can simplify scope, identify the highest-leverage user problem, and distinguish an impressive demo from a valuable product.
  • Experience designing APIs, data models, asynchronous workflows, and integrations with external systems.
  • A strong quality bar for testing, observability, security, reliability, and user experience.
  • Comfort working directly with users and operating in a fast-changing startup environment.
  • AI-native working habits paired with independent technical judgment.

Benefits

  • Competitive Salary and Stock Option Plan.
  • Medical, dental, vision, retirement, leave, and disability benefits as applicable.
  • Family Leave
  • Short Term & Long Term Disability
  • Paid time off and company holidays.
  • Learning and development support.
