Elixir Engineer

Location: Remote – Portugal (Requirement)

Job Overview

We're looking for an Elixir Engineer to join a fast-moving integrations team at a leading SaaS platform. You'll build and operate the connectors that tie the platform to the tools customers rely on daily like Slack, Microsoft Teams, and more across APIs, webhooks, and OAuth. You'll own your work end-to-end, from design through production, and use AI as a natural part of how you engineer.

Responsibilities

Design, build, and ship backend services, APIs, and webhooks that power customer-facing integrations
Maintain highly available, scalable systems across multiple languages and protocols
Integrate with third-party platforms, including Slack and Microsoft Teams
Collaborate with engineers across teams to raise the quality bar throughout the full development lifecycle

Required Skills

4+ years of designing and operating large-scale backend systems
Strong Elixir experience (functional programming mindset essential)
Strong knowledge of React
Solid experience with third-party API integrations, webhooks, and OAuth
Cloud infrastructure experience (AWS preferred)
Proven track record with distributed, highly available systems

Nice to Have

Experience with integrating platforms with Slack, Teams, Jira, or Salesforce
Familiarity with databases and streaming tools (MySQL, Aurora, Kafka, NoSQL)
Experience building public-facing APIs

Mindset & Culture

Ownership-driven: You treat production like it's yours. You built it, you run it, you fix it.
Proactive: You don't wait to be told; you spot problems and improve things before they become issues
Collaborative: You work closely with engineers across teams and communicate clearly
Quality-focused: You care about correctness, observability, and leaving the codebase better than you found it
Continuous learner: New language, new platform, new protocol, you lean in rather than back away
