Principal, Software Engineer

Position Summary...Principal Software Engineer (SRE): Unified Observability Observability
Are you excited by the idea of systems that heal themselves? We're building a unified observability platform that gives 360° visibility across distributed systems, with minimal instrumentation and AI-driven insights that detect, predict, and resolve issues in real time. Our north star is self-healing infrastructure, where AI agents diagnose problems and trigger remediation with little human intervention.
As a principal engineer here, you'll design and deploy scalable AI systems for anomaly detection, forecasting, and root-cause analysis. You'll build real-time inference services and event-driven data pipelines that carry telemetry, logs, metrics, and traces at serious scale. You'll write high-performance Golang backends, architect fault-tolerant multi-cloud systems on Kubernetes, and automate the full MLOps lifecycle. You'll partner closely with SRE and Product teams, shape technical strategy, and mentor engineers who are growing into the next generation of AIOps builders.
If you bring 10–15 years of software experience, hands-on AI Agent deployment from ingestion to monitoring, and a passion for resilient distributed systems, we'd love to meet you. Here, your work keeps millions of customer experiences running smoothly, and your ideas will shape how an entire engineering organization operates. Join us and help build systems that take care of themselves.

What you'll do...

About the team

We are building a unified observability platform that delivers 360° visibility across distributed systems with minimal instrumentation overhead. The platform seamlessly integrates with existing environments and workflows, leveraging AI-driven insights to detect, predict, and resolve issues in real time.

Our goal is to enable self-healing systems through AI agents that autonomously diagnose and trigger remediation actions with minimal human intervention.

What You’ll Do

Core Development

• Design, develop, and deploy scalable AI/ML agents for anomaly detection, forecasting, and root-cause analysis.
• Build and optimize real-time inference APIs and services integrating ML pipelines into production.
• Develop data pipelines for large-scale telemetry, logs, metrics, and traces using event-driven architectures.
• Automate model training, evaluation, and deployment pipelines (MLOps).
• Continuously monitor model performance and optimize for accuracy, latency, and cost.
• Work closely with platform and SRE teams to build AI-powered automation and observability workflows.

Software & Systems Engineering

• Build high-performance backend systems using Golang and modern design patterns.
• Architect distributed and fault-tolerant systems with strong fundamentals in concurrency, scalability, and resilience.
• Design multi-cloud applications using Kubernetes, Docker, and infrastructure-as-code tools.
• Implement service discovery, load balancing, and failure recovery mechanisms.
• Contribute to CI/CD, observability, and automation frameworks for production systems.

Data & Messaging

• Design data flows using Kafka, Pub/Sub, or similar event streaming platforms.
• Work with SQL (PostgreSQL/MySQL) and NoSQL (MongoDB, Cassandra, ClickHouse) databases for structured and unstructured data.
• Implement efficient data serialization, compression, and query optimization for large-scale data.

Collaboration & Technical Leadership

• Collaborate with SRE, DevOps, and Product teams to integrate AI agent features into observability workflows.
• Write clear design documents, architecture diagrams, and technical proposals.
• Contribute to long-term technical strategy and roadmap decisions.
• Mentor junior engineers on best practices in backend, ML systems, and distributed computing.

What You’ll bring

Experience & Education

• 10-15 years of software engineering experience, including 2–4 years in AI/ML engineering.
• Experience deploying AI solution end-to-end (data ingestion → training → inference → monitoring).
• Strong coding skills in Golang (or Python with willingness to learn Go).
• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• Strong understanding of algorithms, data structures, and system design.

AI/ML Expertise

• Good to have experience with ML frameworks such as TensorFlow, PyTorch, or Scikit-learn.
• Hands-on experience with time-series modeling, anomaly detection, or forecasting.
• Exposure to LLMs, RAG pipelines, or agentic workflows for automation.
• Familiarity with MLOps tools like Kubeflow, MLflow, Vertex AI, or SageMaker.

Data & Messaging Systems

• Proficiency with Kafka, Pub/Sub, or similar distributed messaging systems.
• Hands-on with SQL/NoSQL databases and schema design for performance at scale.

Software Engineering Best Practices

• Expertise in designing RESTful or gRPC APIs and scalable microservices.
• Strong focus on testing, CI/CD pipelines, and production readiness.
• Familiarity with observability stacks (Prometheus, Grafana, OpenTelemetry).

Nice to Have Skills

• Experience in real-time observability, AIOps, or incident management platforms.
• Knowledge of distributed consensus (Raft, Paxos) and event sourcing.
• Contributions to open-source ML, observability, or infrastructure projects.
• Familiarity with LLM orchestration frameworks (LangChain, Haystack, Semantic Kernel).
