Member of Technical Staff – AI Inference platform

Lyceum; Zürich; On-site; CHF 120,000 - 170,000; Full time

Job summary

Lyceum, based in Zürich, is building an AI inference platform that must be reliable, secure, and scalable as thousands of concurrent users come online. You will own performance, reliability, and infrastructure evolution, focusing on scalability, observability, and secure multi-tenant operation.

If you love building high‑performance systems and can own critical parts from design to production, join us in shaping Europe’s sovereign AI infrastructure.

Qualifications

• 3+ years of experience in backend, infrastructure, or systems engineering.
• Strong proficiency in Go and Python.
• Experience building or operating a model serving platform or ML platform.
• Solid understanding of systems performance - profiling, benchmarking, and optimising latency and throughput.
• Familiarity with observability tooling (Prometheus, Grafana, OpenTelemetry, or similar).
• Understanding of security fundamentals - network isolation, authentication, encryption, multi-tenancy.

Responsibilities

• Architect and implement scalable systems for thousands of concurrent users, including routing, load balancing, autoscaling, and GPU scheduling.
• Build monitoring, alerting, and incident response tooling to enable graceful degradation and automatic recovery.
• Profile and optimise the full inference path from ingestion to response delivery to reduce bottlenecks.
• Evaluate and integrate open-source inference frameworks and tooling to improve throughput and stability of the serving stack.

Job description

Your mission

You will make Lyceum's AI inference platform reliable, secure, and scalable - ensuring it performs under pressure as we grow to thousands of concurrent users. While others on the team expand what the platform can do, your job is to make sure it keeps working, fails gracefully, and gets faster over time.

Your focus

• Scalability: Architect and implement the systems that allow our inference platform to scale to thousands of concurrent users. This includes request routing, load balancing, autoscaling, and resource scheduling across GPU clusters.

• Reliability and observability: Build robust monitoring, alerting, and incident response tooling. Design for graceful degradation, automatic recovery, and minimal downtime.

• Performance engineering: Profile and optimise the full inference path from request ingestion through model execution to response delivery. Identify and eliminate bottlenecks at every layer.

• Infrastructure evolution: Evaluate and integrate open-source inference frameworks and tooling (Dynamo, vLLM, Triton, etc.) where they improve throughput, latency, or stability of the serving stack.

Your KPIs

• Platform uptime and availability (SLA adherence)

• P50/P95/P99 latency and throughput under load

• Time-to-detection and time-to-resolution for incidents

• Scalability milestones (concurrent users, requests per second, GPU utilisation)

Your profile

We consider candidates from diverse backgrounds, with a deep love for technical challenges and the desire to take on ownership beyond what's reasonably expected.

Requirements

• 3+ years of experience in backend, infrastructure, or systems engineering

• Strong proficiency in Go and Python

• Experience building or operating a model serving platform or ML platform

• Solid understanding of systems performance - profiling, benchmarking, and optimising latency and throughput

• Familiarity with observability tooling (Prometheus, Grafana, OpenTelemetry, or similar)

• Understanding of security fundamentals - network isolation, authentication, encryption, multi‑tenancy

Nice to have

• Experience with NVIDIA Dynamo or similar inference orchestration/routing frameworks

• Hands‑on experience with GPU serving infrastructure (vLLM, Triton, TensorRT‑LLM)

• Experience with Kubernetes in a production environment (deployment, networking, resource management)

• Experience operating at scale (10k+ RPS, multi‑region, multi‑cluster)

• Comfortable working on‑call or in incident response when things break

Why us?

• Outstanding team: Work with some of the best engineers in the world, coming from hedge funds, big tech, AI startups and top universities

• Once in a lifetime opportunity: Early‑stage company in the fastest‑growing market in the world

• Ownership: Shape how European AI companies access GPU compute

• European mission: Build sovereign, GDPR-compliant AI infrastructure for the next generation of deep‑tech
