• Develop and extend a Phoenix LiveView admin portal that enables non-technical teams to manage content, communications, and operational workflows.
• Partner closely with the React Native mobile team to design, version, and ship JSON-based APIs that are reliable and ergonomic for mobile use.
• Design secure authentication/authorization patterns and ensure data is handled securely end-to-end.
• Instrument services for observability (logs/metrics/tracing) and use production signals to drive reliability and performance improvements.
• Collaborate with the Tech Lead and stakeholders to refine requirements, contribute to scoping/estimation, and deliver work in a phased plan.

Requirements

• Proven experience shipping Elixir/Phoenix applications to production, including meaningful ownership of backend features.
• Strong experience with Phoenix LiveView and comfort building server-rendered interactive UIs.
• Strong API design fundamentals for mobile clients: auth, versioning/backward compatibility, rate limiting, retries/idempotency, and well-structured error handling.
• Experience with relational data modeling (e.g., Postgres), background jobs/queues, and operationally safe migrations.
• Practical experience with observability tooling (Telemetry, OpenTelemetry, tracing/monitoring, structured logging).
• Strong written and verbal communication skills; comfortable collaborating in a client-facing environment.

Nice to have

• Experience collaborating with mobile teams (React Native or native) on API contracts, performance, and offline/poor-network behaviors.

• Familiarity with admin UX patterns and building “safe by default” internal tools (audit trails, approvals, permissioning).
• Frontend comfort for LiveView (HTML, CSS, Tailwind).
• Prior consulting/freelance experience.
• Experience with AI-assisted development tools (e.g., Cursor, Claude Code, Copilot).
