Jobs Fullstack

Fullstack Engineer — Automateco

We're a technical agency powering the largest Amazon marketing operation in the United States. Our platform, Signal, is a full-stack intelligence product that surfaces Amazon SEO and performance data for some of the biggest brands in e-commerce — and we're rebuilding it from the ground up with modern tooling and AI at the center.

This is a full-time, fully remote role with exclusive dedication to Automateco. You'll work directly alongside the founding team to migrate a production Laravel + React platform to a modern TypeScript/Node.js/React stack, while layering in AI-driven features that change how our clients understand and act on their data.

What You'll Do

- Own and ship features across the full stack — React frontend, Node.js API layer, and data pipelines
- Lead the migration from a Laravel + React monolith to a TypeScript/Node.js + React architecture
- Build and integrate AI-driven features: intelligent recommendations, automated analysis, and agent-assisted workflows
- Design clean, scalable REST APIs and integrate with third-party data sources (Amazon Advertising, Snowflake, and others)
- Work in fast weekly sprints with a small, senior team — you'll see your work in production quickly
- Deploy and monitor applications on cloud infrastructure; own your services end to end
- Contribute to AI agent architecture decisions as we expand autonomous workflows into the product
- Evaluate and adopt emerging AI tooling to accelerate both the product and our own development process
 

You Bring

- Strong, production-tested experience with TypeScript, React, and Node.js
- Solid grasp of backend architecture: API design, data modeling, auth patterns, performance
- Experience with or genuine curiosity about AI development — LLM integrations, agent frameworks, or AI-assisted workflows
- Comfort migrating legacy systems without breaking production — you think in increments, not rewrites
- Hands-on familiarity with relational databases and data-heavy applications
- A pragmatic mindset: you pick the right tool for the job and don't over-engineer
- Strong debugging instincts and a bias toward clean, maintainable code
- Ability to work independently and communicate clearly in a remote, async-first environment

Nice to Have

- Experience with Laravel or PHP — understanding the system you're migrating from is a real advantage
- Prior work with Amazon Advertising APIs, Snowflake, or e-commerce data pipelines
- Hands-on experience with AI platforms, automation tools (n8n, Make, Zapier), or agent frameworks
- Familiarity with React Query, tRPC, Prisma, or similar modern Node.js stack tooling

Interview Process

- Code review screen (20 min)
- Technical interview with an engineer
- Interview with the founding team

We are looking for a skilled project developer to develop the new version of our current NPS platform. This is a concrete, well-defined project where you take ownership of building the next generation of the system on a solid technical foundation.

A central element of the role is the active use of AI as a core part of the development workflow, including tools such as Claude Code. We expect you to already work AI-first — not just occasionally.

About our system
Relationwise is a SaaS platform for measuring and acting on customer and employee loyalty (NPS/eNPS). At its core it is a survey distribution engine combined with an analytics and reporting platform. The current solution covers, among other things:

• Survey design and configuration with multiple versions per language, region or business unit
• Distribution at scale over email and SMS (Twilio), with Excel-based recipient uploads, validation, scheduling, reminders and telephone follow-up
• A REST API with recipient endpoints, API-key authentication and automatic routing of recipients to the correct survey version; email delivery via SendGrid
• A loyalty dashboard with NPS score, Promoter/Passive/Detractor breakdown, historical trends, a Respondent Explorer with rich filtering and Excel export, plus benchmarking
• Score-based real-time alerts, weekly/monthly summary reports and fully templated notification emails
• Multi-tenant user and access management with per-user data access, roles and an audit log

The platform is built on C#/.NET and integrates with services such as SendGrid (email) and Twilio (SMS). The new system is to be built on Azure or an equivalent cloud platform.

Your primary responsibilities

• Developing the new version of our existing NPS system (C# / .Net / Azure)
• Using AI tools, including Claude Code, as an integrated part of your development work

• Close collaboration with our COO on direction, prioritization and progress

  
  Additional Info

• Fixed-term project position. If the project succeeds, a permanent position may follow.
• On-site at our office in Vejle, Denmark, working directly with our COO. Relocation to Vejle is required — this is not a remote role.

• To support your move, we help you find an apartment near the office and cover its cost for the duration of the project, and we support you through relocation and the work-permit process.

  
  Additional requirements

• Relocation to Vejle, Denmark is a must — you must be able and willing to move and work on-site.
• Ability to design and build the new system on Azure or an equivalent cloud platform
• A demonstrated ability to get high-quality results from AI tools through effective prompting, review and iteration
• At the interview, you will be asked to present examples of projects you have previously built with the help of AI
• As part of your application, please include an estimate of how long you expect it will take to develop the system

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.

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. 

About working at Jakala 

At Jakala, we value our talents and empower our people to express their full potential. People are at the heart of everything we do — a diverse, multifaceted blend of individuals with passion, ambition, and ideas for turning data into value. We give Jakalers a collaborative, supportive environment and the tools, opportunities, and benefits to maximize the impact of their work. 

“Together to get there” is our value proposition because we believe that sharing our abilities is our strength. If this role matches your experience and interests, we'd be glad to hear from you. 

About Jakala 

We are Jakala — a data, AI and experience agency. Our team builds production-grade web applications and applied AI systems for enterprise clients in the healthcare and life sciences space. The work spans multi-agent LLM pipelines, retrieval-augmented generation, data connectors and the web applications that wrap them, delivered to clients who care deeply about accuracy, traceability and compliance. 

We are looking for a Senior GenAI Developer focused on delivery — someone who turns a design into a working, reliable system and ships it. You’ll be strong enough to take a small AI project or proof-of-concept and deliver it largely on your own, and equally comfortable working as part of a team on medium-to-large engagements. This is a hands-on senior individual-contributor role; the emphasis is on building. 

What you’ll do 

• Build and ship. Develop production-grade web applications with AI integration — frontend, backend services and the APIs that connect them. Implement RAG and semantic-search flows, agent orchestration, document/data connectors, and the surrounding application logic. 
• Own delivery of smaller projects end to end. Take a PoC or small AI project from the agreed approach to a working, validated deliverable largely on your own — making sound implementation decisions as you go and flagging the ones that need input. 
• Contribute on larger teams. On medium-to-large projects, own your part of the system, integrate cleanly with other engineers, and keep your components reliable. Participate in technical discussions and contribute to implementation decisions within an agreed architecture. 
• Make AI systems reliable, not just demoable. Handle context windows, token and latency constraints, error and failure modes, and the accuracy/traceability requirements that matter in regulated work. Test what you build, including the behavior of the AI parts. 
• Integrate and connect. Design and consume REST APIs, integrate third-party AI models and enterprise data sources (external APIs, document ingestion, SharePoint and similar), and wire up authentication where needed. 
• Support the team. Review code, share patterns, and help teammates when needed. 

What we’re looking for 

• Strong experience (5 years plus) building and shipping production software full-stack, with hands-on experience integrating LLMs into real applications (at least 1 year). 
• Solid LLM engineering skills: RAG, embeddings and vector search, prompt-engineering patterns, and at least some exposure to multi-agent orchestration. You understand how to make an AI feature behave reliably, not just produce a good first demo. 
• Backend: Python and/or Node.js.  
• Frontend: React, Next.js and/or Vue (component design, state management). 
• Data: SQL, NoSQL and vector databases. 
• Good understanding of REST APIs, integration patterns, Git and branching workflows. 
• Cloud familiarity with at least one major platform — AWS/Bedrock, GCP/Vertex AI or Azure/OpenAI — and the services that back AI workloads. 
• Ability to work independently and take ownership of a deliverable, while also collaborating well inside a team. 
• Effective usage of AI-assisted development tools (Claude, Cursor, Copilot and the like). 
• English sufficient for day-to-day team communication and technical discussion. 

Nice to have 

• Experience in regulated or compliance-heavy domains — healthcare, life sciences, finance — where audit trails and careful data handling matter. 
• Familiarity with evaluating LLM systems (accuracy checks, eval harnesses, regression sets). 
• Unit and integration testing practices (Pytest, Vitest or similar). 
• Infrastructure and delivery breadth: Terraform, Docker/containerisation, CI/CD. 
• Experience with data-integration patterns: external APIs, scrapers, document ingestion, enterprise sources. 

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 the chance to influence technical decisions, in a collaborative team with minimal bureaucracy.
