Your mission

About Us

We're building a new kind of mortgage experience: transparent, digital, and truly customer-centric. We are a Berlin-based B2C Fintech founded by two repeat founders (YC alum, exit) with prior 10+ year careers in investment banking and strategy consulting. We recently raised investment to assemble a 30-person, exceptionally strong core team. Our culture is built on ownership and clarity. We align with you on vision, set clear KPIs and resources together, and then trust your drive and expertise.

The Opportunity

Buying property (and financing it) is probably the biggest financial decision in someone's life. It's complicated and opaque. As a Senior Backend / DevOps Engineer, you will work alongside our CTO on building and evolving our fintech product. Our core architecture and cloud infrastructure are already in place and running in production - you'll spend roughly 70% of your time shipping backend features and 30% on infrastructure and operations. You'll have significant autonomy to shape how we build, deploy, and scale.

Your profile

What You’ll Do

Developing backend features and APIs within our microservices architecture
Designing and implementing event-driven patterns and workflow orchestration
Working with PostgreSQL — schema design, migrations, query optimization
Integrating with external APIs (mortgage platforms, CRM, document processing)
Extending cloud infrastructure (Terraform, Helm) for new services and capabilities
Improving CI/CD pipelines and deployment processes
Implementing monitoring, logging, and observability systems
Optimizing system performance, reliability, and scalability
Collaborating on technical decisions and architecture evolution
Ensuring code quality, security, and operational best practices

Our Stack

Backend: Node.js, TypeScript
Database: PostgreSQL, Redis
Orchestration: Temporal for durable workflows
Architecture: Event Driven Microservices Architecture
Monitoring: Prometheus & Grafana
Cloud: GCP
Infrastructure: Terraform, Helm, GitHub Actions CI/CD, Cloudflare
AI/ML: LLM integrations

What You Bring

Hard Requirements

Strongly-Typed Backend Language: Strong proficiency in at least one strongly-typed, compiled or strictly-typed language (e.g., Go, TypeScript, Rust, Java, C#, Kotlin) for building high-performance backend services. Solid grasp of async patterns, concurrency, and performance optimization.
Event-Driven Architecture: Deep, hands-on experience designing and implementing event-driven systems with messaging patterns (Kafka, RabbitMQ, GCP Pub/Sub, or Redis Streams). You understand eventual consistency, saga patterns, and can articulate trade-offs.
Microservices Architecture: Proven track record building, deploying, and scaling microservice-based systems in production. You know when to split services, how to handle distributed transactions, and how to avoid common microservices pitfalls.
GCP Hands-On Experience: Real production experience with GCP, not just familiarity. You've worked with GKE, Cloud SQL, Memorystore, Cloud Storage, Secret Manager, and can navigate the GCP ecosystem confidently.

Additional Technical Skills

Extensive experience with SQL databases (PostgreSQL preferred)
Strong foundation in RESTful API design
Proficiency with containerization (Docker) and orchestration (Kubernetes)
Experience with CI/CD tools (GitHub Actions, Cloud Build, or similar)
Infrastructure as Code with Terraform or similar tools
Node.js/TypeScript experience is a plus (our current backend stack)
Understanding of observability: structured logging, distributed tracing, metrics, and alerting
Knowledge of API security, authentication/authorization (OAuth 2.0, JWT), and data protection
Experience with workflow orchestration (Temporal or similar) is a strong plus

Mindset & Approach

0→1 Production Experience: You've been through production launches before and know what it takes — setting up infrastructure, handling edge cases, ensuring reliability, and managing the inevitable surprises.
Pragmatic Perfectionism: You balance technical excellence with business velocity, you know when to refactor and when to ship quickly.
Ownership Mentality: You're proactive, resourceful, and accountable for your work, you don't wait to be told what to do.
Team Player: You collaborate well with others, give and receive feedback gracefully, and elevate those around you.
Systems Thinking: You understand how components interact, design for reliability and maintainability, and think beyond your immediate feature.
Clear Communication: You can explain technical decisions to non-technical stakeholders, document your work, and participate constructively in technical discussions.
Continuous Learner: You stay current with industry trends, experiment with new technologies, and are energized by technical challenges.
