Elixir Engineer information

What skills and qualifications are needed to thrive as an Elixir engineer?

To thrive as an Elixir Engineer, you need strong programming skills in Elixir and the Erlang/OTP ecosystem, along with a solid understanding of functional programming principles and concurrent system design. Familiarity with version control systems like Git, experience with Phoenix Framework, and knowledge of deployment tools such as Docker are typically required. Excellent problem-solving, collaboration, and communication skills help you work effectively within development teams and address complex technical challenges. These skills and qualities are essential for building scalable, reliable, and maintainable applications in fast-paced software environments.

What is the difference between Elixir Engineer vs Ruby Developer?

AspectElixir EngineerRuby Developer
Required CredentialsBachelor's in Computer Science or related, knowledge of Elixir and functional programmingBachelor's in Computer Science or related, experience with Ruby and object-oriented programming

Industry UsageTelecommunications, messaging apps, distributed systemsWeb applications, SaaS, e-commerce
Common Search IntentElixir Engineer vs Ruby Developer

Elixir Engineers and Ruby Developers often share similar credentials and work environments, but they focus on different programming languages and application types. Elixir Engineers specialize in scalable, real-time systems using Elixir, while Ruby Developers typically work on web applications with Ruby on Rails. Both roles are vital in modern software development, but their industry applications and technical focuses differ.

What is an Elixir engineer?

An Elixir Engineer is a software developer who specializes in building and maintaining applications using the Elixir programming language. Elixir is known for its concurrency, scalability, and fault-tolerance, making it a popular choice for real-time web applications, distributed systems, and backend services. Elixir Engineers often work with the Phoenix framework and are responsible for designing, developing, testing, and deploying high-performance applications. They may also optimize existing code, ensure system reliability, and collaborate with teams to implement best practices.

How does an Elixir engineer typically collaborate with other team members in a software development environment?

As an Elixir Engineer, you will often work closely with backend and frontend developers, DevOps engineers, and product managers to design and deliver scalable applications. Collaboration is usually facilitated through regular stand-up meetings, code reviews, and pair programming sessions, especially when integrating Elixir services with other parts of a system. You may also be responsible for writing technical documentation and assisting in onboarding team members less familiar with Elixir. Open communication and a willingness to share knowledge are key, as Elixir teams often prioritize code quality and functional programming best practices.

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.
