About the role

You will own the Client Portal(s), the production environment that our clients, from major carbon credit registries to Environmental Project Developers, use to digitize methodologies and run verification workflows on the Hedera network. It is built on the open-source Hedera Guardian platform and our managed Guardian service. You will be the primary engineer keeping it current with upstream Guardian, building client-specific features, and operating it across development, UAT, and production.

This is a hands-on, full-ownership role. You will work across the entire stack: Angular front end, NestJS microservices, authentication, blockchain integration, and the CI/CD and cloud infrastructure that ships it all.

What you will work on

- Build and maintain the Angular portal: complex reactive forms, schema-driven document workflows, comparison views, large-document rendering (Monaco editor), and a polished, branded UI.
- Develop and extend NestJS backend microservices that talk over a NATS message bus and persist to MongoDB.
- Integrate and maintain enterprise authentication: Azure AD B2C / MSAL single sign-on, token lifecycle, automated user provisioning, and HashiCorp Vault for secrets.
- Periodically merge upstream Hedera Guardian releases into our fork, resolving non-trivial conflicts and keeping the portal current (most recently moving the platform up four minor versions in a single sync).
- Work with Hedera Hashgraph (SDK, Guardian Policy Workflow Engine, Verifiable Credentials, IPFS document storage) to support real carbon credit methodologies.
- Own deployment: Docker / docker-compose, Kubernetes manifests, Terraform, and Azure CI/CD pipelines across three environments.
- Build out automated test coverage, which is early-stage today.

Must-have skills

- 5+ years full-stack engineering, with deep TypeScript across both front end and back end.
- Angular (strong: RxJS, reactive forms, Angular Material, SCSS, component architecture). This is the largest part of the codebase.
- NestJS or a comparable Node.js backend framework, in a microservices architecture.
- MongoDB and message-broker-based service communication (NATS, RabbitMQ, Kafka, or similar).
- Docker and container-based deployment; comfortable operating a multi-service application.
- Real experience integrating OAuth/OIDC SSO (Azure AD B2C / MSAL strongly preferred) and reasoning about tokens, sessions, and auth edge cases.
- Able to work independently and own a production system end to end, including reading and merging a large unfamiliar upstream codebase.

Strongly preferred

- Hedera, Hedera Guardian, or other DLT / blockchain experience; familiarity with Verifiable Credentials / decentralized identity.
- Kubernetes, Terraform, and Azure (App Service, B2C) for infrastructure and deployment.
- IPFS or decentralized storage.
- Solidity / smart contracts (the platform includes on-chain contracts).
- Experience working in a fork of a fast-moving open-source project and managing the merge/upgrade cadence.

Nice to have

- Domain knowledge in ESG, carbon markets, dMRV (digital Measurement, Reporting, Verification), or environmental registries.
- Redis, Grafana/Prometheus observability, k6/JMeter load testing.
- Prior experience as the sole or lead maintainer of a customer-facing product.

What makes someone successful here

This is a wide-surface, low-headcount role. The right person is a strong generalist who is comfortable being the one who understands the whole system, from a CSS bug in a nested form to an Azure B2C token race to an upstream platform merge conflict. They should be self-directed, good at reverse-engineering undocumented code, and calm about owning production.

The Opportunity

Max Facilitation is proud to partner with a market-leading European scale-up that is fundamentally redefining how modern enterprises manage their distributed workforces. Recognized recently as one of the Top 10 Startups in the Benelux region, our client provides an automated SaaS ecosystem that handles the complex lifecycle of IT infrastructure—from deployment to retrieval—across 100+ countries.

About Jakala 

We are Jakala — a data, AI and experience agency. Our team builds production-grade web applications and data-driven solutions for enterprise clients, much of which is in the healthcare and life sciences space. This particular team works closely with R&D, automating lab and scientific workflows: building web applications that capture, integrate and surface research data, and the services and integrations behind them. The work rewards engineers who care about correctness, reliability and clean delivery to clients who depend on the results. 

We are looking for a Senior Full Stack Developer to help build and deliver these applications, take ownership of meaningful parts of the system, and contribute to the technical decisions that shape them. As the scope of our work continues to grow, we want an experienced developer who can move comfortably across the stack and raise the quality of what we ship. 

What you'll do 

• Build across the stack. Design, develop and support web applications end to end — frontend interfaces and the backend services and APIs behind them. Build new features, improve existing functionality, and keep the codebase healthy as it grows. 
• Integrate data and services. Design and integrate REST APIs, third-party services and enterprise data sources. Much of the value in lab-automation work comes from reliably getting data in and out of systems, so robust, well-tested integrations matter. 
• Improve performance and reliability. Profile and tune applications, address bottlenecks, and make deliberate choices that keep systems fast, stable and maintainable over the long life of a client engagement. 
• Shape technical decisions. Participate in technical discussions, contribute to architectural choices, review code and support other developers. We want someone who improves the team, not just their own output. 
• Apply AI where it earns its place. Most of our work here is solid full-stack engineering, but AI shows up where it genuinely helps — LLMs for making sense of unstructured data, and the occasional GenAI project between lab-automation engagements. We have also trained a computer-vision model for one engagement. You don't need a machine-learning background, but curiosity about applying these tools well is a real plus. 

What we're looking for 

• 5+ years of experience in full-stack development — you can own a feature from database to UI. 
• Ability to work independently and take ownership of technical solutions. 
• Solid experience with Python on the backend. 
• Strong TypeScript and experience with React or Vue on the frontend. 
• Comfortable writing and maintaining automated tests (Vitest, Pytest, or equivalents). 
• Experience working with relational databases — MySQL and/or PostgreSQL. 
• A good understanding of REST APIs and how to design and integrate them well. 
• Fluency with Git and modern development workflows. 
• Experience with Docker and containerization. 
• Basic AWS or other Cloud infrastructure experience. 
• Upper-intermediate English or above, sufficient for day-to-day communication and technical discussion. 

Nice to have 

• Exposure to AI-related features — LLM integrations, RAG, or AI-powered workflows. 
• Any machine-learning or computer-vision experience. 
• Basic Terraform and CI/CD pipeline knowledge. 
• Familiarity with Flask-RESTful or similar REST frameworks. 
• Experience with data-integration patterns: external APIs, document ingestion, and enterprise data sources. 
• Fluent usage of AI-assisted development tools (Claude, Cursor, Copilot and the like) in your own workflow. 

What you'll get 

• Competitive compensation based on experience and skills. 
• 20 working days of paid vacation plus paid sick leave. 
• Health insurance package. 
• English language classes and learning support. 
• Coverage for courses, certifications, and tech conferences. 
• Fully remote working environment with flexible hours and reasonable overlap for collaboration. 
• Long-term, varied projects with real influence over technical decisions, in a collaborative team with minimal bureaucracy.
