🌟 The mission

Arqh is building the AI dispatcher for road logistics — a route optimizer (MILP, CP, heuristics) fused with LLM agents that handle the communication and coordination around every plan. The hard part isn't only the math; it's making an optimized decision a skeptical dispatcher will actually trust, and closing the loop on the calls, changes, and exceptions that eat two-thirds of their day. Zurich-based, ETH-founded, backed by Founderful & Merantix, and doing already doing this with DACH fleets on the road right now.

🧠 The role

Join as a Senior Platform Engineer (Remote, EU) and own the infrastructure and services that power our product; Kubernetes, microservices, CI/CD, data stores, while staying hands-on across the full stack, including our Python services and React/TypeScript frontend. You'll turn complex planning & routing algorithms into systems that are fast, reliable, and easy to operate.

This is a platform-first, full-stack-capable role: your center of gravity is Kubernetes, microservices, and CI/CD, but you're also comfortable working down into a Python service or up into the React app when a feature needs it end-to-end.

🔍 What you'll do

• Design, deploy, and operate our microservices architecture on Kubernetes — deployments, services, ingress, autoscaling, secrets, config, and rollout/rollback strategy.

• Own CI/CD end-to-end: build pipelines, automated testing gates, progressive delivery, and deployment automation across services.

• Define and enforce platform standards: observability, logging, monitoring, alerting, and incident response across a distributed system.

• Work across MongoDB / Cosmos DB / SQL to model, query, and optimize real workloads.

• Use pub-sub / event-driven patterns for real-time dashboards and system visibility across services.

• Leverage Redis for caching, queues, pipelines, and low-latency coordination between services.

• Ship full-stack features when needed: APIs, data models, and the React/TypeScript UI on top of them.

• Collaborate with product, ops, and customers to turn workflows into robust, observable systems.

✅ Must-have skills

• 5–10 years of experience shipping and operating production systems, with platform/infrastructure ownership as a core part of the role (not a side responsibility).

• Deep, hands-on Kubernetes experience: designing, deploying, scaling, and debugging real workloads in production, not just "familiarity with concepts."

• Strong CI/CD ownership: designing pipelines, automated testing/quality gates, and deployment automation (GitHub Actions, GitLab CI, Helm, or equivalent).

• Solid experience with microservices architecture: service boundaries, inter-service communication, versioning, and failure isolation.

• Docker & Docker Compose for local dev, CI, and production images.

• Solid backend experience in Python (APIs, services, data layer).

• Working React + TypeScript proficiency — enough to ship or debug a full-stack feature independently.

• Solid database experience:

  • MongoDB / Cosmos (NoSQL)

  • SQL (schemas, joins, migrations, performance basics)

• Experience with pub-sub / messaging (Kafka, SNS/SQS, Service Bus, Pub/Sub, etc.).

• Working knowledge of Redis (caching, sessions, queues, pipelines).

• Strong engineering foundations: testing, code review, monitoring, logging.

• Comfortable in a high-ownership, low-ego environment.

• Fluent and advanced English.

• Based in the EU or able to work full-time aligned with EU time zones.

⭐ Nice to have (not required)

• Exposure to LangChain / LangGraph / Langfuse, or agentic/LLM workflow systems more generally (workflow builders, orchestration, evals, tracing) — a bonus, not a requirement.

• Experience with service mesh tooling (Istio, Linkerd), infrastructure-as-code (Terraform, Pulumi), or GitOps workflows.

• Experience in remote-first or async-oriented teams.

👩‍💻 How we work

• Pragmatic engineering: simple first, measurable improvements always.

• Tight feedback loops with customers and ops, you see the impact fast.

• Small team, high ownership, high trust, you shape the stack and standards, from the UI down to the cluster.

• Remote-first in Europe, with core hours around CET.

🚀 What we offer

• High-ownership and impact environment: shape the product and platform foundations of a fast-growing company.

• World-class team: work directly with founders and researchers.

• Fully remote within the EU, plus support for your home office / co-working setup.

• Competitive compensation.
