Company mission
To give access to high-quality prenatal care everywhere.
Role
Who you are
- Sonio is a mission-driven company, so interest in our mission is critical
- 8+ years of software engineering, with 3+ years in Elixir in production at scale (real bottlenecks debugged)
- You have expertise in web & cloud native environment,
- Deep BEAM mastery: GenServers, Phoenix, Ecto / PostgreSQL performance
- Distributed systems in a cloud context: fault tolerance, clustering, consistency/availability trade-offs, back-pressure, and recovery
- Strong architecture and API design; comfortable with event-driven, data-intensive systems
- Written communication is strong enough to author RFCs / ADRs that others use as a reference
- Technical leadership without authority: drives consensus across squads, mentors peers
- Fluent English; French a plus
- Bonus: experience in a regulated environment (medical devices, fintech…), React / TypeScript familiarity
What the job involves
- As a Staff Engineer at Sonio, you will be the ultimate technical authority for our Elixir/Phoenix ecosystem. You will join one of our squads led by Romain (Engineering Manager), which houses the core of our backend codebase
- In this role, you will architect high-scale, resilient systems and arbitrate complex technical decisions to ensure the platform remains performant as we grow. You act as a force multiplier, driving engineering velocity across your squad through strategic design, clear communication, and deep-tier problem-solving
- Be the in-house Elixir / Phoenix expert squads rely on for the deepest problems
- Drive architecture for scale: concurrency, fault tolerance, clustering, back-pressure, recovery patterns
- Own the hardest problems end-to-end—from scoping and design to implementation—while distributing knowledge across the team
- Author RFCs / ADRs for cross-squad changes and review others' designs
- Drive the refactors and tech-debt reductions that unlock velocity
- Grow the team through pairing, code reviews, design reviews and internal talks
- Contribute to senior / staff hiring (case design, tech deep-dives)
- You'll join a growing engineering team with real room to shape how we build
Our take
The interpretation of medical scans, such as prenatal ultrasounds, is very difficult. As such, procedural behaviour can result in missed diagnoses for conditions that should have been looked for, given patient specifics, which is especially dangerous in the field of foetal medicine. Sonio provides AI-software to guide practitioners during ultrasound scans, to optimise prenatal diagnoses'.
Although medical professionals are highly trained, interpretive diagnostic tools such as ultrasound scans present particular challenges, and tools to help better the process are so-far scarce. In particular, finding congenital malformations – or birth defects – in foetuses has proven difficult, as there are numerous conditions with an array of markers. Sonio’s diagnostics combine medical history and genetic data to identify prenatal risks for each patient, highlighting what the physician should be looking for. This is further combined with ultrasound semiology – which searches for markers in the scan – to ensure the practitioner does not overlook anything.
In 2024, the company was acquired by Samsung, a huge move that will benefit the company greatly going forward. While the company is continuing to operate independently, Samsung's software will further enhance its ultrasound tech offerings.
