Senior Software Engineer Applied AI

• 7+ years building and operating production backend systems, with strong general-purpose programming skills (we work primarily in Python)
• Experience running distributed systems in the cloud; comfortable debugging from telemetry to root cause
• Hands-on production experience with LLMs or generative AI (any provider or framework), plus the judgment to know when not to use a model
• Working fluency across the traditional machine learning lifecycle (you productionize; you do not need to publish)
• Disciplined in a regulated environment: small, reviewable changes and careful handling of sensitive data

Nice-to-haves

• Real-time media or telephony experience
• Front-end / full-stack ability
• ML pipeline experience, vector search, or embeddings
• Fluency with AI coding assistants (our workflows assume them, with human accountability for every change)

How we work

Smallest correct change wins. Every behavior change is validated against the live system. Evidence over opinion in debugging. Code review is rigorous. Safety and privacy gate everything.

• Streaming, low-latency speech-to-speech systems built on modern LLMs
• Telephony and real-time media (call control, live audio streaming)
• Audio handling and the quirks of real human conversation (interruptions, timing, noise)
• Concurrency on a latency-sensitive path, where p99 matters and a stall is something a caller hears

LLM engineering

• Wrapping nondeterministic models in deterministic control so they behave reliably in production
• Multi-model pipelines, prompt design, and cost/latency budgeting
• Evaluation harnesses, including LLM-as-judge and automated agent-tests-agent approaches
• Agentic tooling that gives AI systems safe, structured access to infrastructure

Traditional (non-LLM) machine learning

• End-to-end ML pipelines: feature engineering, model training, and scheduled inference
• Imbalanced, messy real-world data; calibration and explainability for non-technical consumers
• Turning research notebooks into reproducible, auditable production pipelines

Cloud and infrastructure

• Infrastructure as code across multiple environments (we run on AWS)
• Managed compute, data, streaming, and orchestration services
• Security engineering in a regulated setting: encryption, least-privilege access, strict data-handling discipline
• Observability and telemetry-driven debugging, tracing a production issue from a metric anomaly to root cause

Plus occasional full-stack work on internal tools, and an engineering workflow that leans heavily on AI coding assistants, with human accountability for every change.

What you’ll actually do

• Ship and debug code on a live, real-time voice pipeline where latency and correctness are user-facing
• Design control systems around LLMs: guardrails, budgets, watchdogs, safe fallbacks
• Build and operate LLM evaluation and batch-analysis pipelines
• Own traditional ML workflows from data to scheduled production inference
• Trace production issues from a metric anomaly to root cause, including building the evidence when the cause is a vendor
