Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design, build, and operate high-load distributed backend services that power the company's machine learning infrastructure. Partner with ML and product teams to turn their needs into reliable, reusable platform capabilities.
Requires 5+ years of professional experience in backend or platform engineering with extensive Python knowledge. Candidates must have hands-on experience with public cloud platforms and building distributed, high-load services.
Launched in 2019, Constructor is an AI-first e-commerce search and discovery platform that helps shoppers find the right products at the right time and enables leading global e-commerce brands to drive meaningful revenue and conversion gains.
The ML Infrastructure team builds and operates the shared backend services and platform capabilities that Constructor's ML and product teams rely on to develop, deploy, and run machine learning at scale - from model serving (including LLMs) to the specialized storages and data pipelines behind it.
We are a service team by nature: our roadmap is shaped by the needs of product teams, and we succeed when they can move faster with less friction. We're looking for a Senior Backend Engineer who is comfortable with, and motivated by this dynamic, and who will take end-to-end ownership of core services.
In the near and mid-term, our focus areas include:
Making ML workloads easy to run, scale, and operate for every team
Providing self-service, configurable infrastructure components to ML and product teams
Owning and evolving core ML services and related pipelines with a high bar for reliability and performance
Design, build, and operate high-load distributed backend services that power the company's ML infrastructure
Take end-to-end ownership of core ML services and related data pipelines: from design and implementation to deployment, observability, and continuous improvement
Partner with ML and product teams to understand their needs and turn them into reliable, reusable platform capabilities
Make and defend technical decisions: evaluate trade-offs, design first, and own the outcome
Be responsible for what you and your team do
5+ years of professional experience in backend or platform engineering
Extensive Python knowledge (our primary language)
Hands-on experience developing on a public cloud (AWS, GCP, or Azure) or with self-managed Kubernetes - AWS is our primary platform, but we're not limited to it
Experience designing and building distributed, high-load services and APIs
Strong knowledge of data structures, algorithms, and their trade-offs
Design-driven engineering mindset: we're a coding-assistant-friendly environment and expect you to use modern AI tools - but you lead with system design and a strong understanding of their applicability and trade-offs
Ownership and proactivity: you can't close your eyes to problems, but are ready to solve them and take responsibility for outcomes
You are friendly and willing to help your teammates & others
Experience with Rust (or C/C++/Go) - a strong plus
Experience developing or contributing to ML platforms or ML infrastructure - a strong plus
Experience setting up and operating any vector database (Qdrant, Milvus, Weaviate, OpenSearch, pgvector, etc.) - a strong plus
Experience with model serving / inference infrastructure, including LLMs
Experience with Infrastructure as Code (Terraform or similar)
🏝️ Unlimited vacation time - we strongly encourage all of our employees take at least 3 weeks per year
