If you want to work in a place where your growth matters as much as the results, we are looking for you.

Senior Full‑Stack Software Engineer

Main Responsibilities:
• Design, build, and operate modern web applications supporting scientific and AI workflows, including frontend user interfaces, backend services, and data integrations.
• Develop rich, high‑performance data visualization experiences such as dashboards, exploratory analytics, and interactive visual components to support scientific interpretation.
• Build and maintain secure and scalable RESTful and/or GraphQL backend services, integrating internal systems, databases, and external APIs.
• Work closely with data scientists and domain experts to integrate ML/AI components, model inference pipelines, and data processing workflows into user‑facing products.
• Apply software engineering best practices including automated testing, code reviews, CI/CD, documentation, containerization, and monitoring.
• Collaborate in cross‑functional, research‑driven environments to transform high‑level scientific and business requirements into robust, scalable, and user‑friendly solutions.

Requirements:

Mandatory:
• University degree in Computer Science, Engineering, Bioinformatics, or related fields (M.Sc. or PhD is a plus).
• 5+ years of professional experience building production‑grade web applications and backend services, with demonstrable full‑stack end‑to‑end delivery in data‑rich domains.
• Strong frontend development skills using modern JavaScript/TypeScript and Python‑based frameworks (e.g., Streamlit, Flask, React, Next.js, Vue).
• Hands‑on experience with data visualization frameworks such as D3.js, Plotly, Vega‑Lite, or ECharts, and ability to build intuitive, information‑dense scientific UIs.
• Strong backend engineering proficiency with Python, using frameworks such as FastAPI, Flask, or Django, including asynchronous programming patterns and background job processing.
• Expert‑level SQL and data modeling for analytical and transactional workloads, with experience using relational databases (Postgres, MySQL) and in‑memory stores (Redis).
• Proven experience designing and consuming secure, scalable RESTful APIs; familiarity with OAuth/OIDC, JWT, rate limiting, and secure coding practices.
• Hands‑on experience deploying and operating applications on AWS (ECS/EKS, Lambda, S3, RDS, CloudFront) and using Infrastructure as Code (Terraform/CloudFormation) and CI/CD pipelines.

Nice to Have:
• Experience designing advanced scientific visualizations (multi‑dimensional data, temporal or spatial visualizations, imaging, omics) and conducting UX research with scientific stakeholders.
• Experience integrating applications with data platforms such as Databricks or Snowflake.
• Familiarity with ML/AI deployment patterns, including working with model endpoints (SageMaker, Vertex, MLflow), feature stores, or retrieval/search architectures.
• Polyglot programming experience (Go, Rust, Java) for performance‑critical components.
• Exposure to scientific datasets (omics, imaging, clinical, preclinical) and understanding of associated standards, governance, and privacy considerations.

Offered
• Permanent contract with a competitive salary
• Flexible working model and remote work options
• Personalized career plan and continuous training (certifications, English programs, etc.)
• Participation in stable projects with a high technical component
• Flexible schedule and work–life balance
• Social benefits adapted to your needs
