What is Elixir?

Elixir is a programming language used on the Erlang virtual machine. This platform offers a framework for fault-tolerant coding and engineering, with a particular focus on web development and software applications. A key feature of Elixir is its focus on lightweight coding and built-in tools for running tests and remote debugging. The focus on web applications also means that Elixir handles topics like scaling to handle many users at the same time. Elixir is a functional programming language that is easy to read and relatively easy to learn, making it a popular choice for companies that want to produce web-based applications outside of a browser environment.

What is an Elixir developer?

Elixir developers are software engineers who specialize in building applications using the Elixir programming language. Elixir is a dynamic, functional language designed for building scalable and maintainable applications, especially for concurrent and distributed systems. Elixir developers often work on backend services, real-time systems, and web applications, leveraging the Erlang VM for fault-tolerance and high performance. They are skilled in writing efficient code, designing systems for concurrency, and often use frameworks like Phoenix for web development.

What are the key skills and qualifications needed to thrive as an Elixir developer, and why are they important?

To thrive as an Elixir Developer, you need strong programming skills in Elixir and functional programming concepts, typically supported by experience in backend development. Familiarity with the Phoenix framework, distributed systems, and tools like Git, Docker, and CI/CD pipelines is commonly expected. Problem-solving abilities, teamwork, and effective communication are standout soft skills in this role. These competencies ensure the development of scalable, reliable applications and smooth collaboration within dynamic engineering teams.

What are some common challenges faced by Elixir developers when working in teams, and how can they be effectively addressed?

Elixir developers often work in environments where concurrent and distributed systems are key, which can lead to challenges in coordinating code changes, managing shared resources, and ensuring clear communication among team members. Effective collaboration often relies on maintaining well-documented code, utilizing version control best practices, and participating in regular code reviews. Teams can further address these challenges by adopting common conventions for structuring Elixir projects and leveraging tools like collaborative chat platforms or pair programming sessions to share knowledge and resolve issues quickly.

What is the difference between Elixir vs Software Developer?

AspectElixirSoftware Developer
Required CredentialsTypically requires knowledge of Elixir language, functional programming, and related toolsRequires a degree in computer science or related field; programming skills in various languages
Work EnvironmentOften in tech companies, startups, or companies using functional programmingVaries widely; tech, finance, healthcare, and more
Industry UsagePrimarily in software development, especially in scalable, concurrent systemsBroad; includes all sectors involving software development
Common Search & ComparisonElixir vs Software Developer

Elixir is a programming language focused on scalable, concurrent applications, often used in specific tech environments. Software Developers have a broader role, encompassing various languages and industries. While Elixir specialists focus on functional programming, Software Developers may work with multiple languages and technologies across different sectors.

Job description

CollX is changing the face of card collecting, bringing computer vision, machine learning, and other technology to the Hobby. We began by solving a very simple and age-old problem: helping collectors figure out what their cards are worth. The CollX app, launched in early 2022, enables anyone to snap a photo of a trading card, instantly ID it, and get the current market value. From there you can scan your collection, follow your friends, and buy, sell or trade with others. The app has quickly grown to more than 3.6M users, who have scanned over a billion cards.

Job Description

We’re looking for a Senior Elixir Developer to join our growing team. We've hit the limits of horizontal scaling and batch processing. We're dealing with billions of entities, streaming data across auto-scaling clusters, and every architectural decision has real consequences. This isn't about building faster CRUD apps—it's about fundamentally different engineering challenges.

We’re Looking For Someone who:

  • Has been here before. You've debugged distributed systems in production, planned migrations that can't have downtime, and built things that handle massive load.
  • Has built systems that don't fit on one machine. You understand why consistent hashing matters, why you can't just "add more servers," and when eventual consistency is your friend (and when it's your enemy).
  • Thinks in streams, not batches. Real-time data processing across distributed systems is your wheelhouse. You've debugged backpressure issues, dealt with partitioning strategies, and know why ordering guarantees are harder than they look.
  • Has made the hard architectural choices. You understand the tradeoffs between consistency, availability, and partition tolerance—not just as theory, but as daily reality.

Our Stack & Scale

  • Continuous deployment with zero-downtime requirements
  • Billions of entities requiring careful data modeling
  • Streaming architectures where batch processing isn't an option
Job Responsibilities
  • Design systems that work at scale. Every table change, every new feature requires serious architectural consideration. You'll be making decisions that affect performance and reliability for years to come.
  • Support the software delivery lifecycle from design to implementation
  • Collaborate with interdisciplinary teams to conduct automation testing and check for performance bottlenecks
  • We’re a small company, so whatever else may come up that you can help with!
Job Requirements
  • Degree in Engineering, Computer Science (or equivalent experience)
  • Mastery of Elixir
  • Solid understanding of GraphQL
  • 8+ years of relevant experience as a software developer
  • Prior experience developing mobile applications is a plus
  • Demonstrable experience in building marketplace facilitation systems is a plus
  • Excellent communication and collaboration skills
Why Join CollX?
  • Be part of a small, nimble, and fast-growing company that’s reshaping the sports card industry.
  • Work alongside passionate collectors, entrepreneurs, and industry leaders.
  • See the impact of your work consistently and quickly, operating with increased autonomy and decision-making.
