**About Us**
Ares Materials is a Series B startup building **Minerva**, a platform that captures scientific experiments for traceability and powers AI/ML-driven insights. With Minerva v1.0 deployed, we’re growing adoption among lab scientists and need to strengthen our technical foundation to ensure trust, security, and scalability.
We are looking for a **Backend Engineer (Full-time)** to own **security, data integrity, robust APIs, and ML integrations**. This is a critical hire who will help transform Minerva into a trustworthy and reliable platform that scientists use every day.
**What You’ll Do**
You’ll be the primary owner of backend engineering for Minerva, responsible for:
- **Security & Permissions (ABAC)**: Design and implement attribute-based access control, authentication/authorization patterns, audit logs, account lifecycle management, and least-privilege defaults.
- **Data Model & Integrity**: Own schemas, migrations, validation, idempotent writes, and background jobs to ensure clean, reliable data capture.
- **Core APIs**: Build stable, versioned APIs for experiments, samples, and runs. Support integrations with ML tools and downstream dashboards.
- **DevOps & Reliability**: Establish CI/CD pipelines, testing frameworks, staging environments, seeded test data, and error tracking/observability.
- **Performance**: Optimize queries and workflows to reduce scientists' time-to-record and improve perceived product value.




- **ML Integration Surface**: Create APIs for ML pipelines.
**What We’re Looking For**
- **Experience**: 4+ years of backend engineering experience (or equivalent impact).
- **Technical Skills**:
- Proficiency in **Flask (or similar Python frameworks)**.

- Strong testing discipline (unit, integration, regression).
- **Mindset**:
- Bias for ownership and delivery.
- Comfortable working in mínimal-process, startup environments.
- Strong judgment in data modeling and trade-offs.
**Why Join Us**
- Build software that directly supports cutting-edge scientific research and AI/ML.
