SLNG is building global, compliance‑first voice AI infrastructure. We operate across STT, TTS, LLMs and real‑time voice systems, running workloads on globally distributed compute. We are early stage, technical by default, and moving quickly. This is not a volume recruiting role. This is an execution‑heavy role working directly with the founders.
The role
You will own day‑to‑day recruiting execution across technical and non‑technical roles, reporting directly to the founder. You will draft roles from rough input, source candidates through technical communities, and run a clean, high‑signal hiring process. You will not be responsible for closing senior candidates solo. Founders remain directly involved in final decisions and senior closes.
What you will do

Draft role descriptions from incomplete or evolving input (founder‑reviewed)
Source candidates across ML, infra, MLOps, DevOps, SRE, and systems roles
Engage thoughtfully with technical communities in Spain
Run first‑pass screens focused on motivation, judgment, and role fit
Manage the hiring process end‑to‑end (scheduling, feedback, coordination)
Hire junior and mid‑level roles with increasing autonomy over time

Technical context you should be comfortable operating in

Machine learning infrastructure and model lifecycle
Model serving and low‑latency inference
Distributed and real‑time systems
Reliability and performance‑sensitive infrastructure
GPU‑heavy workloads and cost‑aware systems
Streaming, event‑driven, and networking‑heavy systems

Requirements

3–6 years recruiting experience
Experience in an early‑stage startup environment
Experience recruiting technical roles (infra, ML, platform, systems)
Ability to work from unclear inputs and iterate quickly
Strong written communication and role‑drafting ability
Barcelona‑based with interest in local technical communities. You should already be operating in the Barcelona ecosystem.
