Betarchitect

At betarchitect, we are building a high-performance, event-driven iGaming B2B platform. We prioritize performance and cost-efficiency, which is why we’ve chosen a lean, powerful infrastructure over "standard" AWS-bloated stacks. We are looking for a Senior DevOps Engineer to own our infrastructure, automation, and security protocols.

You will be responsible for managing our production Kubernetes clusters on Hetzner, automating everything with Terraform, and ensuring our NX-based monorepo (NestJS/NextJS) deploys seamlessly and securely using SOPS and Age.

Key Responsibilities

• Infrastructure as Code: Provision and manage Hetzner Cloud and Bare Metal resources using Terraform.
• Kubernetes Orchestration: Maintain and scale production-grade Kubernetes clusters (K3s/Kubeadm) on Hetzner, optimizing for low latency and high availability.
• GitOps & Secret Management: Implement and manage secure secret workflows using SOPS and Age, ensuring no sensitive data hits Git in plaintext.
• CI/CD Optimization: Maintain the deployment pipelines for our NX monorepo, optimizing build times and deployment strategies for NestJS microservices and Next.js frontends.
• Edge & Networking: Manage Cloudflare configurations (WAF, Workers, DNS, and Load Balancing) to ensure global performance and security.
• Data & Messaging Ops: Support the reliability of our event-driven architecture, specifically managing connectivity and scaling for PostgreSQL, Kafka (event propagation), and ClickHouse Cloud.
• Security & Compliance: Ensure our infrastructure meets iGaming industry standards for AML/CDD and general data security.

Technical Requirements

• Hetzner Guru: Extensive experience with Hetzner Cloud, Dedicated Servers, and their Private Networking/Robot API.
• Kubernetes Expert: Deep knowledge of K8s internals, CNI plugins (Calico/Cilium), and Ingress controllers.
• Secret Management: Proficiency with SOPS + Age for encrypting secrets within a GitOps workflow (Flux/ArgoCD experience is a plus).
• IaC: Expert-level Terraform skills, specifically with the hcloud and cloudflare providers.
• Monorepo Savvy: Experience handling large-scale NX monorepos and optimizing Node.js-based build targets.
• Fullstack Awareness: Understanding of NestJS (backend) and Next.js (frontend) deployment requirements (SSR, ISR, etc.).
• Networking: Strong understanding of Cloudflare proxying, SSL management, and DDoS mitigation.
• Ability to write custom Python or Bash scripts for infrastructure automation.

Nice to Have

• Experience in the iGaming or FinTech industry (EMI licensing/compliance knowledge).
• Experience with Postgres CDC / Outbox patterns and Kafka operations.
• Knowledge of Supabase (Auth/Database) and ClickHouse scaling.

Job Overview

We are looking for an experienced Senior Backend Engineer to join our engineering team. You will play a pivotal role in architecting and building high-performance, scalable microservices using NestJS.

In this role, you will tackle complex data challenges, optimize database interactions, and ensure event-driven consistency across our platform. The ideal candidate is a hands-on technical leader who loves strictly typed systems, efficient data pipelines, and clean API design. 

Key Responsibilities

• Architect & Build: Design, develop, and maintain scalable microservices using NestJS (TypeScript).
• Database Optimization: Manage complex data modeling and query optimization for high-load environments using PostgreSQL and ClickHouse.
• Event-Driven Systems: Implement and manage event-driven architectures using Apache Kafka to ensure reliable data streaming and service decoupling.
• API Management: Design and document RESTful APIs using the OpenAPI (Swagger) specification, ensuring contract-first development and seamless frontend integration.
• Real-time & Auth: Leverage Supabase for real-time subscriptions, authentication flows, or rapid prototyping where applicable.
• Code Quality: Enforce code standards through rigorous code reviews, automated testing (Jest/Supertest), and CI/CD pipelines.
• Mentorship: Mentor junior and mid-level engineers, providing technical guidance and fostering a culture of engineering excellence.

Technical Requirements

• NestJS Expert: 5+ years of backend development experience, with deep expertise in NestJS and the Node.js ecosystem.
• Relational Data: Advanced proficiency with PostgreSQL, including optimization, indexing, and raw SQL queries.
• Big Data Analytics: Production experience with ClickHouse for analytical processing and handling large datasets.
• Event Streaming: Strong experience with Apache Kafka (producers, consumers, partition strategies, and schema registries).
• Microservices: Proven track record of decomposing monoliths or building microservices from scratch (gRPC, RabbitMQ, knowledge is a plus).
• API Standards: Mastery of OpenAPI/Swagger tools to generate clients and documentation automatically.
• Supabase: Experience integrating Supabase (PostgREST, Realtime, or Auth) into a custom backend architecture.
• Testing: Strong belief in TDD/BDD, with proficiency in writing unit and integration tests.

Nice-to-Have

• Experience with containerization and orchestration (Docker, Kubernetes).
• Knowledge of Redis for caching strategies.
• Experience with Infrastructure as Code (Terraform).
• Familiarity with GraphQL.

Soft Skills

• Problem Solver: You enjoy digging into complex performance bottlenecks and solving them efficiently.
• Communicator: You can explain complex architectural decisions to non-technical stakeholders.
• Owner: You take full ownership of your features, from design to deployment and monitoring.

Why Join Us?

• Competitive Salary: We value your expertise and pay accordingly.
• Remote-First Culture: Work from where you are most productive.
• Tech-Forward: We are constantly evaluating and adopting the best tools for the job (like the stack mentioned above).
• Professional Development: Budget for courses, conferences, and certifications.
• Long Term Position: Stable and long term position.
