Job Description
Senior Software Engineer at Sona building next-gen AI-native workforce solutions, directly interacting with users and owning features end-to-end.
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
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
Benefits:
- 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
