Senior Software Engineer, Inference Platform

Mongo

DB’s mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data. We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, Mongo

DB Atlas, is the only globally distributed, multi-cloud database and is available in more than 115 regions across AWS, Google Cloud, and Microsoft Azure. Atlas allows customers to build and run applications anywhere—on premises, or across cloud providers. With offices worldwide and over 175,000 new developers signing up to use Mongo

DB every month, it’s no wonder that leading organizations, like Samsung and Toyota, trust Mongo

DB to build next‑generation, AI‑powered applications.

About the Role

We’re looking for a Senior Engineer to help build the next-generation inference platform that supports embedding models used for semantic search, retrieval, and AI-native experiences in Mongo

DB Atlas.

You’ll join the broader Search and AI Platform organization and collaborate with ML researchers and engineers from our Voyage.ai acquisition. Together, we’re building infrastructure for real‑time, low‑latency, and high‑scale inference — fully integrated with Atlas and designed for developer‑first experiences.

As a Senior Engineer, you'll focus on building core systems and services that power model inference 'll own key components of the infrastructure, work across teams to ensure tight integration with Atlas, and contribute to a platform designed for reliability, performance, and ease of use.

We are looking to speak to candidates who are based in Palo Alto or Seattle for our hybrid working model.

What You’ll Do

• Design and build components of a multi‑tenant inference platform integrated directly with Mongo

DB Atlas, supporting semantic search and hybrid retrieval

• Collaborate with AI engineers and researchers to product ionize inference for embedding models and rerankers — enabling both batch and real‑time use cases

• Contribute to platform capabilities such as latency‑aware routing, model versioning, health monitoring, and observability

• Improve performance, autoscaling, GPU utilization, and resource efficiency in a cloud‑native environment. Work across product, infrastructure, and ML teams to ensure the inference platform meets the scale, reliability, and latency demands of Atlas users

• Gain hands‑on experience with tools like vLLM and container orchestration with Kubernetes

Who You Are

• 5+ years of experience building backend or infrastructure systems at scale

• Strong software engineering skills in languages such as Go, Rust, Python, or C++, with an emphasis on performance and reliability

• Experienced in cloud‑native architectures, distributed systems, and multi‑tenant service design

• Familiar with concepts in ML model serving and inference runtimes, even if not directly deploying models

• Knowledge of vector search systems (e.g., Faiss, HNSW, ScaNN) is a plus

• Comfortable working across functional teams, including ML researchers, backend engineers, and platform teams

• Motivated to work on systems integrated into Mongo

DB Atlas and used by thousands of developers

Nice to Have

• Experience integrating infrastructure with production ML workloads

Understanding of hybrid retrieval, prompt‑driven systems, or retrieval‑augmented generation (RAG)
Contributions to open‑source infrastructure for ML serving or search

Why Join Us

• Be part of building the AI foundation of the world’s most popular developer data platform

• Collaborate with ML researchers from Voyage.ai to bring novel ideas into scalable systems

• Tackle challenging problems in inference, observability, and distributed infrastructure

• Work in a culture that emphasizes mentorship, ownership, and technical excellence
