Senior Platform (Full-Stack) Engineer

Senior Platform (Full-Stack) Engineer 🌟 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. If this sounds like you, we'd love to hear from you! CV and cover letter are required; certificates, GitHub portfolio, and recommendation letters are highly beneficial.
