About The Role A hands-on player-coach. You write production code daily — designing ports, building adapters, reviewing every PR — and you own the architecture, set engineering standards, break the roadmap into work for three developers, and represent the team technically to Roche stakeholders. This is not a purely managerial or purely architectural seat: roughly 60% hands-on engineering, 40% technical leadership.

Job Title: Technical Lead

Key Responsibilities

• 8+ years in software / data engineering, including 2+ years in a technical lead, staff, or architect capacity with direct responsibility for other engineers' output.
• Expert Python for production systems: OOP and abstract base classes, type hints, packaging, dependency management; comfortable authoring a library others build on.
• Proven software architecture experience with clean / hexagonal (ports & adapters) architecture, dependency injection, and interface-driven design — demonstrable on real systems, not just theory.
• Snowflake — hands-on production experience (databases/schemas, roles/warehouses, cloning, access model).
• AWS — hands-on production experience building and operating services on AWS.
• CI/CD with GitLab (or equivalent) — designing pipelines that build, test, and deploy.
• Infrastructure as Code with Terraform — authored and maintained real infrastructure.
• Secure secret management — hands-on experience keeping credentials/secrets out of code, logs, and state and sourcing them from a secrets backend (e.g. HashiCorp Vault, AWS Secrets Manager / Parameter Store).
• Concept-level mastery (can explain how they work and design for them, independent of any specific vendor tool) of: data governance, data warehousing, data transformation, and data ingestion/ETL.
• Strong SQL (to design and validate backend/migration adapters — not for production data work).
• Professional working English and the communication skills to lead a distributed team and brief non-engineering stakeholders.
• Orchestrators beyond CI: Airflow / Dagster.

Minimum Qualifications Experience: 8+ years in software/data engineering, including 2+ years in a tech lead, staff, or architect role managing others.

Tech Stack: Expert Python, strong SQL, AWS, Snowflake, Terraform, GitLab CI/CD, Airflow/Dagster, and secure secret management.

Architecture & Skills: Proven hexagonal/clean architecture experience, strong data domain mastery, and fluent English communication for leadership.
