Job Summary
Principal Engineer
CoCounsel is our most advanced AI offering to date combining generative and agentic AI capabilities to help legal professionals move beyond prompting and start delegating. As a Principal Software Engineer focused on Cloud Cost Optimization you will be the embedded go-to expert within Product engineering for how cloud and AI/model spend is tracked forecast and reduced without sacrificing reliability or user experience. You will partner closely with the platform/infrastructure team (who own provisioning and LLM-serving architecture) AI/ML engineers product and FinOps to make cost a first-class engineering concern inside the product team.
About the Role
In this opportunity as a Principal Software Engineer you will:
Be the teams cost optimization authority:Serve as the go-to resource for cloud and AI-inference cost questions within the product engineering team identifying quantifying and driving high-impact optimization opportunities across compute storage and model usage.
Analyze and tune LLM usage for cost efficiency:Partner with AI/ML and platform teams to right-size model selection routing and usage patterns (batching caching prompt/response size provider mix) for cost-efficiency without regressing quality or latency SLAs.
Own cost tracking and forecasting tooling:Build and maintain dashboards showback/chargeback reporting and forecasting models that give the product team visibility into spend per feature per workflow and per customer segment.
Advise on elasticity and caching from a cost lens:Work with platform engineering on auto-scaling caching and queuing designs weighing in specifically on cost/performance tradeoffs rather than owning the underlying architecture.
Cross-functional influence:Lead cost-reduction initiatives that cut across product AI/ML and platform teams. Mentor senior/staff engineers on cost-aware engineering practices and FinOps habits.
Cost observability and governance:Establish spend-related SLOs budget alerts and anomaly detection; lead the response when spend deviates unexpectedly.
About You
You are a fit for the position of Principal Software Engineer if your background includes:
Bachelors Degree in CS/CE or equivalent experience.
Solid hands-on cloud infrastructure experience (AWS preferred) compute networking storage IaC (Terraform/CloudFormation) with a demonstrated focus oncost not just architecture.
Experience analyzing and optimizing cost/performance of production LLM-serving systems (multi-provider routing caching batching); you dont need to have built the serving platform but you need to understand it deeply enough to find savings in it.
Track record driving cross-team cost optimization initiatives with measurable quantified dollar impact at scale.
Working proficiency in Python (or similar) and enough familiarity with FastAPI/Kubernetes/distributed systems to read instrument and reason about production code and infra.
FinOps practices and tooling for cloud and inference cost at scale (forecasting chargeback/showback budget governance) this is now core not a nice-to-have.
Observability/reliability practices as applied to spend cost SLOs dashboards anomaly alerting incident response for cost spikes.
Strong communication across product AI/ML platform and FinOps stakeholders.
Preferred Skills & Experience:
GPU/accelerator infrastructure and inference optimization (batching quantization custom serving) still highly relevant since inference is usually the largest cost driver.
Track record building or customizing FinOps tooling in-house.
Familiarity with vector databases/embeddings/retrieval pipelines specifically to reason about their cost footprint.
Multi-region/multi-cloud cost tradeoffs (not required to own DR architecture).
