Senior Machine Learning Backend Engineer

As a Senior Machine Learning Backend Engineer, you'll architect and build the high-performance backend systems that power Gong's AI at massive scale, craft real-time ML serving innovative solutions, and play a pivotal role in our mission to revolutionize the way companies understand their customer interactions. We're seeking a Java professional who can leverage their deep knowledge to drive our backend development to new heights.

You will be responsible for:

ML Serving Architecture: Design and implement high-performance inference APIs and model serving backends using Java & Python.
Model Lifecycle Management: Build systems for model versioning, A/B testing, canary deployments, and automated rollbacks.
Integration Platform: Create robust APIs and SDKs that enable product teams to integrate AI capabilities seamlessly.
Observability & Monitoring: Build comprehensive metrics, logging, and tracing systems for ML workloads.
Cross-team Leadership: Mentor engineers & researchers, drive technical decisions, and influence platform architecture across the organization.

You should apply if you have:

6+ years of hands-on experience in large-scale backend development, with strong emphasis on Java programming and building high-performance AI/ML inference systems.
Strong analytical and problem-solving skills, with the ability to debug and resolve complex technical issues in AI applications serving millions of requests daily.
Experience with cloud platforms (AWS preferred, Azure, or Google Cloud) and building scalable microservices architectures for AI model serving and data processing pipelines.
Advantageous experience with ML frameworks (TensorFlow, PyTorch), model serving platforms (Triton, TorchServe, KServe), and building high-throughput AI-powered APIs and data processing systems.
Excellent communication skills, both verbal and written, with the ability to articulate technical AI system design decisions clearly and collaborate effectively with ML engineers, data scientists, and DevOps teams.
A Bachelor's degree in Computer Science, Engineering, or a related field is preferred. Experience with AI/ML systems in production environments is highly valued.

*We operate in a flexible hybrid work model.

Scale That Matters
We're not just another ML team - we're powering AI that directly impacts how thousands of companies understand their customers. Our platform serves 40M+ inference requests daily, scaling to hundreds of millions, with real business consequences riding on every millisecond of latency.

Research Meets Production
We bridge the gap between cutting-edge AI research and bulletproof production systems. Our engineers work directly with researchers to take models from paper to production, solving novel challenges in LLM serving, real-time inference, and GPU optimization that don't have Stack Overflow answers.

Technical Excellence at Speed

Sub-100ms p95 latency while serving dozens of models simultaneously
99.9% uptime for business-critical AI features used by enterprise customers
Continuous deployment of new models without service interruption
Cost optimization that saves millions while improving performance

️ Full-Stack Ownership
You won't just maintain existing systems - you'll architect the next generation of ML infrastructure. From GPU cluster design to API optimization, from model lifecycle management to observability platforms, you'll own the complete stack.

Future-Forward Challenges
As AI transforms from feature to core product differentiator, we're solving tomorrow's problems today: multi-modal AI serving, LLM optimization, real-time personalization at scale, and building the infrastructure that will power the next generation of AI-driven products.
