🌐 Full Stack Developer — Automating AI Workflows in Insurance

Summary

We’re building end-to-end automation for AI tasks in the insurance sector. Over the next 10 months, we’ll be prototyping before launching a dedicated spinout. You’ll work closely with our Senior AI CTO (30+ years of combined AI experience across the team) in a fast-paced but supportive environment.

This is a full-time, remote-first role (office available in Berlin). You’ll be expected to make strong use of AI tools to accelerate development and — even more importantly — debug efficiently. Success in this role requires both technical ability and a willingness to dive into the business logic of how insurance actually works.

What You’ll Do

• Develop and maintain backend services in TypeScript, using frameworks like Mastra, AWS Lambda, and Next.js
• Prototype and ship features that automate complex insurance processes
• Work with the CTO on model integration (potentially fine-tuning later in the roadmap)
• Debug and optimize workflows using AI tools for rapid iteration
• Build a deep understanding of insurance workflows to translate domain needs into technical solutions

What We’re Looking For

• Strong experience with TypeScript and modern frameworks (Next.js, serverless/Lambda)
• Ability to quickly learn and apply new tools like Mastra for workflow automation
• Comfort using AI coding assistants — not just to write code, but to debug effectively
• Curiosity to understand business logic in insurance and apply it to product design
• Availability for full-time commitment in a distributed, remote-first team (EU time zones preferred)
• Fluency in English or German

Nice to Have

• Experience with AI model integration or fine-tuning
• Background in automation, workflow orchestration, or backend-heavy applications
• Previous exposure to insurance, fintech, or other regulated industries
• Open-source contributions (any scale — show us what you’ve built!)
• If you speak German, it would be much easier to integrate into the team. 

We are seeking a hands-on Senior Database Administrator with deep expertise in PostgreSQL and MySQL. You’ll design, deploy, maintain, and optimize highly available, scalable database systems. Familiarity with SQL Server, MongoDB, and cloud-native database services (AWS RDS, Google Cloud SQL, Azure Database) is a strong advantage. Candidates with database migration experience (on-prem → cloud or cross-cloud) will be given preference.

Key Responsibilities
- Architect, configure and maintain PostgreSQL and MySQL instances in production
- Define schemas, indexing strategies, partitioning, and sharding as needed
- Implement and manage replication, clustering, failover, and backup/recovery solutions
- Develop and test disaster-recovery plans and runbooks
- Monitor query performance, tune SQL, and optimize configurations
- Collaborate on capacity planning and cost-optimization initiatives
- Plan and execute migrations (e.g., on-prem to cloud, between cloud providers)
- Lead version upgrades, schema changes, and data transformations
- Implement monitoring (Prometheus, Grafana, etc.), alerting, and logging
- Define and enforce security best practices (access controls, encryption)
- Automate routine tasks and deployments using Bash, Python, Ansible, or similar tools
- Partner with Development, DevOps, and Data teams on schema design, ETL pipelines, and query tuning
- Document database architectures, standard operating procedures, and runbooks

Required Qualifications
3 years managing PostgreSQL in production
3 years managing MySQL in production
Hands-on with AWS, GCP, or Azure managed database services (e.g., RDS, Cloud SQL)
Advanced SQL (indexing, query optimization, partitioning)
Backup & recovery strategies, replication, high-availability configurations
Scripting/automation (Bash, Python, Ansible, etc.)
Proven track record of database migration projects (e.g., PostgreSQL → cloud, MongoDB → Atlas, SQL Server upgrades)

Preferred Qualifications
- Familiarity with additional databases (MongoDB, SQL Server, Neo4j, other NoSQL)
- Experience with ETL tools, BigQuery, or data-warehousing concepts
- Certifications in PostgreSQL, MySQL, or cloud platforms (AWS, GCP, Azure)
- Exposure to DevOps practices and infrastructure-as-code (Terraform, CloudFormation)
