**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 **Python Developer (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 **PostgreSQL performance tuning** and schema design skills. * Experience with **AWS fundamentals** (IAM, RDS, ECS/Beanstalk, containerization). * Authentication \& authorization patterns (JWT, session management). * Strong testing discipline (unit, integration, regression). * **Mindset:** * Bias for ownership and delivery. * Comfortable working in minimal\-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. * Own a critical part of the platform from the ground up. * Work in a small, focused team where your impact is highly visible. * Competitive salary (Depending on seniority). * Growth opportunities as Ares scales.
