Contract Elixir Developer information

What are Contract Elixir Developers?

Contract Elixir Developers are software engineers who specialize in developing applications using the Elixir programming language, typically on a contract or freelance basis rather than as full-time employees. They are often hired to build, maintain, or optimize scalable and concurrent web applications, leveraging Elixir's strengths for performance and reliability. Their work may involve collaborating with teams, integrating Elixir with other technologies, and writing clean, maintainable code. Contract roles offer flexibility in terms of project length and work arrangements, making them a popular choice for companies needing specific expertise in Elixir for a defined period.

What are the key skills and qualifications needed to thrive as a Contract Elixir Developer, and why are they important?

To thrive as a Contract Elixir Developer, you need strong proficiency in Elixir programming, functional programming principles, and experience with web frameworks like Phoenix, ideally supported by a relevant degree or proven project work. Familiarity with version control systems like Git, CI/CD pipelines, and cloud platforms such as AWS or GCP is often required, along with knowledge of testing frameworks. Excellent problem-solving, communication, and time-management skills set top contractors apart in remote or dynamic environments. These skills ensure the delivery of robust, scalable applications and smooth collaboration with distributed teams under tight deadlines.

What is the difference between Contract Elixir Developer vs Contract Ruby Developer?

AspectContract Elixir DeveloperContract Ruby Developer
Required CredentialsProficiency in Elixir, functional programming, and related frameworksProficiency in Ruby, object-oriented programming, and Rails
Work EnvironmentTypically startups, tech companies, or projects needing scalable, concurrent systemsOften web development, startups, and companies using Ruby on Rails
Employer & Industry UsageEmerging in telecom, fintech, and scalable backend servicesWidely used in web development, e-commerce, and SaaS platforms
Search & Comparison IntentOften compared for backend scalability and functional programming benefitsCompared for web app development and rapid deployment

Contract Elixir Developers focus on scalable, concurrent systems using Elixir, while Contract Ruby Developers specialize in web applications with Ruby on Rails. Both roles require strong programming skills but differ in language, frameworks, and typical industry applications.

What types of projects and team structures can a Contract Elixir Developer expect to encounter?

As a Contract Elixir Developer, you will often work on projects that require scalable, high-performance backend systems, such as real-time applications, APIs, or distributed systems. Teams are typically agile and cross-functional, often including other backend developers, front-end engineers, DevOps specialists, and product managers. You may join projects at various stages, from initial architecture planning to ongoing maintenance or feature development. Collaboration is usually remote, and clear communication is essential to align with client requirements and team goals. The contract nature of the role also means you should be comfortable with quickly adapting to new codebases and workflows.

Staff Developer, Fullstack AI

Healthcare Outcomes Performance Company (HOPCo)

Job description

This role owns the fullstack experiences where clinicians and operators meet Hopper’s AI. That includes the conversational and agentic interfaces (chat, voice, streaming, and tool-calling) that let people interrogate clinical data and drive workflows in natural language, along with the AI-powered features woven directly into HopperOS. The developer turns model output into interfaces that are fast, legible, and trustworthy at the point of care, building across the full stack against Hopper’s clinical data contracts.

ESSENTIAL FUNCTIONS

  • Conversational & Agentic AI Interfaces
    • Own the agent experience across chat and voice interaction, streaming responses, conversation history, and model-generated titles and summaries.
    • Make model reasoning legible by surfacing tool calls, citations, intermediate steps, and uncertainty.
    • Build low-latency, real-time experiences over WebSockets and streaming APIs that stay responsive under clinical conditions.
    • Render dynamic model output into on-the-fly charts, tables, and structured clinical summaries.
    • Partner with the CIE and orchestration team to expose tiered model routing, skills, and reasoning in ways users can trust and act on.
  • AI-Powered Clinical Product
    • Embed AI into HopperOS workflows, including documentation and ambient-scribe surfaces, inline suggestions, and natural-language query over clinical and operational data.
    • Build against Hopper’s data contracts, including the FHIR API surface and Athena-integrated clinical data.
    • Ship the rich, interactive product surfaces where interactivity clearly adds value.
  • Craft, Evaluation & Iteration
    • Own fullstack quality for AI features, including streaming UX, performance, accessibility, and responsiveness across desktop and point-of-care tablet and mobile.
    • Close the loop with evals by measuring the quality of generated UI and agent responses.
    • Work forward-deployed with real clinician and operations users, incorporating feedback into design and build-out.

EDUCATION & CERTIFICATIONS

  • Bachelor’s degree in Computer Science, Software Engineering, or a related technical field. Equivalent professional experience will be considered.
  • Certifications in cloud, AI/ML, or modern web development preferred.

EXPERIENCE

  • 5+ years building and shipping production web frontends or fullstack products, ideally with 0-to-1 ownership.
  • Hands-on AI product experience building chat or agent UIs, tool-calling, streaming responses, and app-layer context and prompt management.
  • Strong frontend craft across component-driven UI, state management, and real-time interfaces (WebSockets, streaming); experience with React is a plus, though craft and adaptability matter more than any specific framework.
  • Experience turning structured and unstructured model output into UI that is dynamic, legible, and trustworthy.
  • Healthcare or clinical software experience, including familiarity with FHIR/HL7 or EHR integration (e.g., Athena), preferred.

KNOWLEDGE

  • Systems-level UX judgment, with the ability to reason about latency, failure modes, and safety in AI experiences.
  • Familiarity with agent architectures and tool-calling systems end to end.
  • Knowledge of LLM evaluation tooling (e.g., Braintrust) and voice interfaces.
  • Understanding of ML and LLM model development; curiosity about Elixir/Phoenix or computer vision a plus.

SKILLS & ABILITIES

  • Strong product instincts, comfortable prototyping live with users and shipping feedback within days.
  • A feel for the model boundary between raw model output and trustworthy, legible UI.
  • Strong collaboration across clinical, product, and engineering stakeholders.
  • Adaptability to work in a fast-paced, greenfield environment and go deep in whatever stack the problem needs.

ENVIRONMENTAL WORKING CONDITIONS

  • Normal office environment
  • May require some travel

PHYSICAL/MENTAL DEMANDS

  • Requires sitting and standing associated with a normal office environment.
  • Manual dexterity using a calculator and computer keyboard.

ORGANIZATIONAL REQUIREMENTS

  • HOPCo Mission, Vision and Values must be acknowledged and adhered to
