sona - Senior Software Engineer (Elixir)
Requirements
• 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
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
Benefits
• Remote-first (Europe timezone) with quarterly in-person sessions and client workshops in London • Share options • 35 days annual leave (25 days standard plus 10 flexible public holiday days) • Extra day of leave for every year of service • Pension contributions matched up to 5% • Comprehensive health insurance • Enhanced parental leave & pay • Co-working space stipend for those based outside London • Annual all expenses paid team retreats • The latest Macbook and equipment budget for your home office • Professional development budget • Unlimited free books • Note: this represents a typical salary and benefits package for a UK-based, full-time employee.
