About the role

Senior Elixir engineer role at Sona, remote-first in Europe, embedded in product teams, leveraging AI tooling to direct and correct agent-produced code, with opportunities to rotate across product domains (scheduling, payroll, HR, staff engagement).

Responsibilities

  • Own features end-to-end across Sona's platform, from scoping through to delivery, including in the mobile app
  • Use AI development tooling as your primary workflow - directing and evaluating agent-produced code, not writing everything from scratch
  • Work directly with customers through workshops, feedback sessions, and discovery conversations to ensure what you build solves real problems
  • Collaborate closely with Product Managers and Product Designers to shape solutions from vague requirements and kick-off outputs
  • Contribute to multiple product domains across the year, building deep understanding of workforce management challenges
  • Participate in the product development process - challenging scope, suggesting approaches, and making pragmatic trade-offs between the ideal solution and the right one for now

Qualifications

  • You're a senior engineer who's comfortable owning features from scoping to production - not just executing against a spec
  • You have professional Elixir experience - enough to evaluate and correct agent-produced code in a production codebase
  • AI development tooling is already embedded in how you work, not something you've experimented with once or twice. You can articulate your workflows and demonstrate them under pressure
  • You care about understanding customer problems as much as solving technical ones, and you're comfortable being in front of customers directly
  • You communicate clearly and concisely - adapting for technical and non-technical audiences alike
  • You're pragmatic: you can let go of a strongly held opinion when the situation calls for it, and you make trade-offs consciously
  • Bonus: full-stack experience including React Native, background at a product-led engineering team or high-growth B2B SaaS company, or familiarity with HR/workforce management domains
