What are some common challenges Elixir developers face when building scalable applications?

Elixir developers often encounter challenges related to designing and maintaining distributed, fault-tolerant systems, especially as applications scale. Managing process supervision, optimizing for concurrency, and ensuring reliable message passing can require careful architectural decisions. Additionally, integrating Elixir with existing systems or third-party services may present learning curves, particularly when working with legacy technologies or databases. Collaboration with DevOps and QA teams is also essential to ensure smooth deployments and ongoing system reliability.

AspectElixir DevelopmentRuby on Rails Developer
Required CredentialsBachelor's in Computer Science, knowledge of Elixir and OTPBachelor's in Computer Science, knowledge of Ruby and Rails
Work EnvironmentDistributed systems, scalable backend servicesWeb application development, startup and enterprise web apps
Employer & Industry UsageTech companies focusing on real-time, concurrent systemsWeb development agencies, e-commerce, SaaS companies
Common Search & ComparisonElixir DevelopmentRuby on Rails Developer

Elixir Development and Ruby on Rails Developer roles share similarities in web and backend development but differ in technology focus. Elixir is ideal for scalable, concurrent systems, while Ruby on Rails is popular for rapid web application development. Both roles require programming skills and are in high demand across tech industries.

What is Elixir development?

Elixir development refers to the process of creating software applications using the Elixir programming language, which is known for its scalability, fault-tolerance, and functional programming features. Elixir runs on the Erlang Virtual Machine (BEAM) and is widely used for building distributed, real-time, and high-performance systems such as web applications, APIs, and messaging platforms. Elixir developers leverage frameworks like Phoenix to build robust and maintainable applications, particularly when concurrency and reliability are important. The language's syntax is friendly and its ecosystem offers powerful tools for testing, deployment, and monitoring.

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 a strong background in functional programming, proficiency with Elixir and the Phoenix framework, and a solid understanding of concurrent and distributed systems. Familiarity with tools such as Mix, Ecto, and version control systems like Git is typically required, and experience with cloud platforms or Docker can be beneficial. Strong problem-solving skills, attention to detail, and effective communication are essential soft skills for collaborating with teams and building scalable applications. These qualities are crucial for developing reliable, maintainable software that leverages Elixir’s strengths in performance and fault-tolerance.

Userpilot

Austin, TX • On-site

Full-time

Re-posted 9 days ago

Job description

About Userpilot
Userpilot is a leading product analytics and user engagement platform used by product teams at hundreds of companies to understand, segment, and activate their users. The product spans a performant JavaScript SDK that runs inside customers' web apps, a Chrome Extension for building in-app UI without code, and a React dashboard that handles complex real-time data - all backed by a distributed Elixir/Phoenix backend that sustains hundreds of thousands of concurrent WebSocket connections, high-throughput Kafka event ingestion, and real-time content delivery at scale.
We move fast, we ship often, and we believe the best engineers care as much about the product they're enabling as the systems and interfaces they build.
The Role
This is a full-stack, AI-native role. You'll work across the entire product from the React dashboard and embedded SDK down to the Elixir services and real-time pipelines, and you'll do it in a spec-driven, agent-assisted way. You'll also help build the AI-powered features our customers use, not just use AI to build everything else.
We've stopped treating frontend and backend as separate jobs. We hire engineers who can follow a problem wherever it leads, and who use AI tooling to go deeper and faster rather than to paper over gaps in judgment.
What You'll Work On
  • The Userpilot dashboard: a React monorepo (Nx + Vite + Yarn Workspaces) with 50+ product domains, shared design-system components, and live analytics views
  • The JavaScript SDK: a lightweight, performance-critical script embedded in customer applications that renders personalized UI experiences
  • Real-time backend services: the Elixir/Phoenix channels, Kafka consumers, ClickHouse write buffers, and RabbitMQ-backed integrations that ingest analytics events and make them available for queries and engagement triggers in near real-time
  • WebSocket infrastructure: the persistent connections that keep hundreds of thousands of concurrent users in sync
  • AI-powered product features: LLM-driven personalization, streaming experiences, and in-product intelligence, including the non-deterministic UI and backend states they require
  • Agentic development infra: the AGENTS.md, CLAUDE.md, DESIGN.md, slash commands, and architectural rules that make AI coding tools safe and effective across both a complex React codebase and a strict Elixir/OTP one

What You'll Do
  • Design, build, and operate features end-to-end - from accessible React/TypeScript UI through to the Elixir/Phoenix services, pipelines, and data stores behind them
  • Build AI-powered product features and the infrastructure around them - streaming responses, AI-driven personalization, and the guardrails that make non-deterministic behavior safe in production
  • Care about performance on both sides - bundle size, rendering efficiency, and Core Web Vitals on the frontend; throughput, correctness, and reliability in distributed real-time backends
  • Translate product specs and design mockups into production features, using the right tool for the job - React Query, Redux, and Saga on the client; OTP patterns, queues, and write buffers on the server
  • Work in a spec-driven flow - read and contribute to PRDs that drive both human and AI-assisted implementation
  • Contribute to the team's agentic infrastructure - AGENTS.md, CLAUDE.md, DESIGN.md, slash commands, and .rules/ - so AI tooling understands our codebase as well as the humans do
  • Review code for architectural consistency and maintainability across the stack - including making sure agent-generated code respects the same boundaries human-written code does - and expect the same in return

What We're Looking For
Required
  • 3+ years building and shipping production software, with hands-on experience on both the frontend and backend of real applications
  • Frontend: production React + TypeScript - solid component design, hooks, rendering behavior, and experience with server/client state management (React Query, Redux, or Redux-Saga)
  • Backend: strong CS fundamentals (data structures, algorithms, software design) and professional experience building services in a high-level language (Elixir, Ruby, Python, Go, or similar), including work with databases, queues, or real-time systems
  • AI features: experience building or integrating LLM-powered features - streaming responses, AI-driven personalization, or otherwise designing for non-deterministic behavior
  • AI-native workflow: you use AI coding agents (Claude Code, Cursor) as a real part of how you build - prompting for scaffolding, reviewing output critically, and knowing when to push back
  • Strong product sense and judgment - you care about the user experience and about system correctness in equal measure
  • Self-management and a continuous-improvement mindset - we don't over-prescribe how the work gets done

Bonus Points
  • Elixir and the Phoenix framework with OTP - it's what our backend runs on, and its patterns (supervision trees, cache invariants, channel rules) exist for good reasons
  • Building and operating reliable real-time systems at scale and knowing what "reliable" actually means in production
  • Kafka, RabbitMQ, ClickHouse, Broadway, or similar high-throughput data tooling
  • MUI or design-system experience - we build on top of MUI with a custom layer (Blueprint)
  • Monorepo tooling (Nx, Turborepo, or similar)
  • Chrome Extension development, or SDK / embeddable-script work with size and performance constraints
  • Familiarity with spec-driven development - writing or working from specs that drive both human and AI implementation, and knowing what makes a good one
  • Contributing to developer experience or agentic infra - agent context files (AGENTS.md, CLAUDE.md), runbooks, architectural decision records, slash commands, linting rules, scaffolding
  • Optimizing cloud and infrastructure costs through caching or more efficient data processing
  • Technical leadership on an engineering team
  • Open source contributions
  • Writing tests (unit, integration, e2e) - we won't gate on it, but we'll notice

Our Stack
  • Frontend: React 18, TypeScript, Vite, Nx, Yarn Workspaces
  • State management: React Query, Redux, Redux-Saga
  • Design system: MUI-based component library with a custom layer (Blueprint) on top
  • Backend: Elixir 1.14+, OTP, Phoenix 1.7
  • Databases: ClickHouse (analytics), MySQL (primary)
  • Messaging: Kafka (kafka_ex), RabbitMQ (amqp), Broadway
  • Infrastructure: AWS, Kubernetes, Docker
  • Background jobs: Oban
  • AI: LLM-powered product features (streaming, AI-driven personalization); Claude Code / Cursor for agentic development
  • CI: GitHub Actions

What "Agentic Engineering" Means Here
We're not just using AI to write code faster; we're changing how we build, and AI-powered features are part of the product itself. Two things are true at once: coding agents help us ship, and our customers increasingly use AI features we've built. Both demand the same discipline.
  • Features start with a written spec - a PRD that captures intent and constraints - not a two-line ticket, whether the implementer is a human or an agent
  • Coding agents (Claude Code, Cursor) do the scaffolding; engineers own the architecture, the review, and the judgment calls
  • Our patterns are encoded explicitly. Every umbrella app and product domain has an AGENTS.md capturing what it does, the patterns it uses, and the mistakes to avoid - so an agent working on core doesn't violate a cache invariant or write directly to ClickHouse, and an agent on the dashboard doesn't break a design contract
  • Code review isn't only about correctness - it's about making sure agent-generated code respects architectural boundaries the same way human-written code has to, on both the React and Elixir/OTP sides
  • DX is a product: if a new engineer (or an AI agent) can't understand a domain from its documentation and rules, that's a bug we fix
  • Building AI features means designing for non-determinism - streaming, retries, evals, and graceful failure - and holding it to the same reliability bar as the rest of the platform

You don't need to have done all of this at your last job. But you should be genuinely curious about it, comfortable moving across the whole stack, and excited to help shape how we build.
