What is a full stack software engineer?

A full stack software engineer develops all aspects of a software application, from the user interface to the back-end database. As a full stack software engineer, your job duties include gathering customer requirements, writing the code to develop the application, and troubleshooting the application for any issues. The qualifications to pursue a career as a full stack software engineer include an associate or bachelor’s degree in computer science, software engineering, or a related field and proficiency in a variety of coding languages and frameworks.

What are the key skills and qualifications needed to thrive as a full stack software engineer, and why are they important?

To thrive as a Full Stack Software Engineer, you need strong proficiency in both front-end (e.g., HTML, CSS, JavaScript) and back-end (e.g., Node.js, Python, Java) development, typically supported by a relevant degree or equivalent experience. Familiarity with frameworks (like React or Angular), version control (such as Git), databases (SQL/NoSQL), and cloud platforms is essential, and certifications like AWS Certified Developer can be beneficial. Problem-solving ability, collaboration, and adaptability are vital soft skills that help engineers navigate complex projects and work effectively in teams. These skills ensure the ability to deliver robust, scalable, and user-friendly applications that meet dynamic business needs.

What is the difference between Full Stack Software Engineer vs Front End Developer?

AspectFull Stack Software EngineerFront End Developer
Required SkillsProficiency in both front-end and back-end technologies, including HTML, CSS, JavaScript, server-side languages, and databases.Specializes in client-side technologies like HTML, CSS, JavaScript, and frameworks such as React or Angular.
Work EnvironmentWorks on both server and client-side development, often involved in full project lifecycle.Focuses primarily on designing and implementing user interfaces and user experience.
Common UsageUsed in full-stack development teams, startups, and projects requiring versatile developers.Found in teams emphasizing UI/UX, web design, and front-end frameworks.

While both roles require strong JavaScript skills, Full Stack Software Engineers handle both front-end and back-end development, whereas Front End Developers focus solely on the user interface and experience. The choice depends on whether you prefer a broader development scope or specialization in UI design.

How do full stack software engineers typically collaborate with other team members during a development project?

Full Stack Software Engineers often work closely with front-end and back-end developers, UI/UX designers, product managers, and QA testers throughout the software development lifecycle. Collaboration typically involves participating in agile ceremonies such as daily stand-ups, sprint planning, and code reviews to ensure alignment and progress. They are expected to communicate effectively across disciplines, help troubleshoot issues that span both client and server sides, and contribute to shared documentation. This collaborative environment helps ensure that solutions are cohesive, scalable, and meet user requirements.

Job description

About Pure
Pure is building the future of rare coin and precious metal trading. We believe collectors and investors deserve financial infrastructure that matches the standards of modern markets. That is why we are creating a new kind of order book marketplace that brings transparency, efficiency, and trust to an industry still rooted in legacy systems.
Started in 2023, Pure is one of the fastest growing marketplaces for tangible assets. We currently process over $45 million in transactions each month and are expanding rapidly. Our mission is to modernize an old industry by combining the reliability of traditional trading systems with the innovation of cutting-edge technology.
What You Will Be Doing:
  • Lead and own critical features and subsystems end-to-end - from design through to deployment. You will make key technical decisions, set priorities, and deliver fast without sacrificing quality.
  • Build, maintain, and scale our marketplace backend including order matching / order-book logic with concurrency, correctness, and speed in mind; transaction flows, payments, reconciliation; ensuring data integrity, auditability, resilience.
  • Build and refine our frontend / UI/UX using TypeScript + Next.js: translate designer UX flows into high quality components; optimize performance (SSR vs client side, code splitting, lazy loading, etc.).
  • Work deeply with PostgreSQL: data modeling, query optimization, indexing, schema design, ensuring performance as data and load grow.
  • Develop and improve internal tools ("Nimbus") for accounting, logistics, operations dashboards, fraud detection, monitoring, etc.
  • Lead small teams or mentor other developers: provide code reviews, help unblock teammates, set best practices.
  • Drive process improvements, technical architecture, testing strategy, observability. Be hands-on in incidents or urgent problems.

Who You Are:
  • Have 3+ years of full stack engineering experience (or equivalent), especially in startup or fast-paced environments.
  • Are comfortable leading yourself and others - owning features / systems, guiding teammates, making decisions.
  • Are hands-on: you write and ship code, prototype, fix bugs, and also think about architecture and scalability.
  • Strong front-end experience with TypeScript + Next.js, good eye for UX / UI, performance, accessibility.
  • Strong backend experience: Node.js (or similar), working with PostgreSQL, comfortable with designing schema, writing efficient queries, handling transactions and consistency.
  • Excellent problem solver: you understand trade-offs between speed, maintainability, architecture, and are pragmatic.
  • Good communicator: able to translate business / operations / design needs into technical work, and explain trade-offs.
  • Self-driven, independent: you do not need constant supervision; you push things forward, and also know when to ask for feedback.

Bonus:
  • Experience building marketplaces, matching engines, or financial or trading systems.
  • Experience working with design systems, component libraries, or UI frameworks.
  • Experience with scaling backend services, optimization, monitoring, observability.

What We Offer:
Flexible work arrangements: Remote, hybrid, or in-office in L.A.
Health coverage & insurance: Medical, dental
Retirement: 401(k) with employer match
Extras & perks: Daily lunches, Wellness stipend
We move fast. We prioritize shipping with quality, reliability, and correctness.
Ownership matters. You will have autonomy and be expected to lead and follow through. If you are excited and can do core things well, even if you do not match every box, apply.
