Saphetor is a Swiss precision medicine company with offices in Lausanne (CH), Boston (USA), and Athens (GR) employing a diverse global workforce.
The Opportunity
We are looking for a C++ Developer to join our backend team. If you're driven by clean code, cross team collaboration and excited to work in the fast moving world of genomics, this is a place where your work will matter.
We thrive in a high-pressure, high-performance environment where clinical precision and rapid growth meet. While our pace is fast, it is always directed by rigorous organization and clear processes, ensuring that our commitment to quality is never compromised by our drive for speed.
Role Responsibilities:
- Code Craftsmanship: Write reusable, testable, and efficient code — backed by thorough unit and regression tests that keep the platform reliable as it evolves.
- Core Engineering: Develop our core C++ applications and library for importing and analyzing genetic data.
- Project Ownership: Take complete ownership of projects ranging from a few days to a month, delivering working end-to-end implementations from design through testing and deployment.
- Performance & Scale: Assist in the optimization and architecture of our platform for maximum speed, high availability, and scalability — pushing the limits of what's possible with large-scale genomic data.
- Annotation Tooling: Maintain and improve our internal high-performance clinical annotation tools and the custom databases purpose-built and optimized for genetics workloads.
- Documentation & Knowledge Sharing: Contribute to clear, lasting documentation of software architecture and implementation details so the team can build on.
- Cross-Team Collaboration: Partner with backend engineers, bioinformaticians, and product stakeholders to scope work, align on interfaces, and deliver cohesive end-to-end features.
The Ideal Candidate (Profile)
The ideal candidate is a C++ Developer with hands-on experience writing modern C++. You write high-quality, well-tested code and you are comfortable engaging in code reviews and cross-functional work with other stakeholders.
What you will bring:
- Academic Foundation: BS or MS degree in Computer Science.
- C++ Expertise: At least 3 years of professional experience as a back-end developer working with C++ (preferably with C++ 17 or later), templates, STL containers, smart pointers, memory management and multithreading.
- Database Skills: Hands-on experience with relational databases, including optimizing queries and table schemas for peak performance.
- Distributed Systems: Solid experience with distributed cloud-based computing and big-data systems.
- Design Principles: Good grasp of fundamental application design and object-oriented principles, essential for building and maintaining a large, high-quality codebase.
- Active Engagement: Participate in code reviews and technical discussions.
- Communication: Excellent written and oral communication skills in English.
- Team Player: Flexible mindset, comfortable stepping into a variety of roles as needed.
Strongly Valued:
- In-Memory & RPC Tech: Experience with in-memory databases like Redis and gRPC services.
- Domain Interest: Some bioinformatics background — or a genuine willingness to dive into the domain.
While our foundation is in Athens, our talent pool is spread across Europe, with a strong culture of remote collaboration. Our team is highly experienced in distributed Agile workflows and communicates exclusively in fluent English.
Your career journey with us includes, among others:
- A position in a fascinating healthcare growth domain, at the cutting edge of technology and research
- A competitive compensation package tailored to your unique expertise and professional background.
