You will collaborate directly with SRE managers, development leaders, architects, and product owners to ship AI-first tooling that scales with the platform. Design and build full-stack AI-powered applications using Angular frontends, Python/FastAPI backends, and integrated LLM and agent pipelines. Develop and operationalize LLM-based solutions for SRE use cases, including log analysis, anomaly detection, runbook automation, incident triage, and RCA summarization. Implement RAG (Retrieval-Augmented Generation) pipelines over operational knowledge bases and runbooks. Integrate AI/ML models into SRE observability tools like New Relic and automation workflows, including monitoring, alerting, and self-healing. Build and maintain RESTful and async APIs using FastAPI for internal SRE tooling and dashboards. Develop Angular dashboards that present AI-generated insights to SRE, account, and sales stakeholder teams. Collaborate with the Cloud Automation team on AI-driven infrastructure automation using Terraform, Ansible, and Jenkins. Enforce engineering best practices, including code reviews, unit testing, and CI/CD pipelines for both ML and application code. Evaluate and introduce emerging AI frameworks and LLM providers, including OpenAI, Azure OpenAI, Bedrock, LangChain, and LlamaIndex. Maintain Kubernetes-deployed AI workloads and troubleshoot inference latency, scaling, and reliability issues. Participate in the on-call rotation and apply AI tooling to improve incident response times. Coach and mentor team members on AI integration patterns and best practices. Qualifications & Experience Must have solid experience of AWS/Azure DevOps, Terraform and Ansible Bachelor’s degree in a technical field and 8–12+ years of professional experience in software or platform engineering. Proven hands-on full-stack development experience with Angular (TypeScript) frontends and Python backends in production environments. Strong Python proficiency, including FastAPI, async patterns, Pydantic, and SQLAlchemy or an equivalent ORM. Direct experience building and deploying LLM-integrated applications, including prompt engineering, function calling, RAG pipelines, and agent frameworks such as LangChain, LlamaIndex, AutoGen, CrewAI, or equivalent. Familiarity with LLM providers and APIs, including Azure OpenAI, AWS Bedrock, OpenAI API, or open-source models such as Llama and Mistral. Experience with vector databases and embedding workflows, including Chroma, Weaviate, pgvector, Azure AI Search, or equivalent. Solid understanding of CI/CD pipelines for application code and ML/AI artifacts, including MLflow, DVC, or equivalent. Strong container and orchestration skills with Docker and Kubernetes, including the ability to deploy and troubleshoot AI inference workloads. Public cloud experience with Azure and/or AWS, including compute, storage, networking, and managed AI services such as Azure OpenAI and SageMaker. Understanding of SRE/DevOps principles, including SLOs, error budgets, observability, incident management, and toil reduction. Experience integrating with observability stacks such as Prometheus, Grafana, ELK/OpenSearch, Datadog, or equivalent. Strong interpersonal and communication skills, with the ability to explain AI capabilities and limitations to non-technical stakeholders. Preferrably  Preferred: Experience with Microsoft Copilot Studio for building enterprise Copilot agents and connectors integrated with M365 and Azure AI services. Familiarity with AI agent orchestration patterns, including multi-agent systems, tool-use loops, and memory management. Experience with fine-tuning or PEFT (LoRA/QLoRA) of open-source LLMs for domain-specific SRE tasks. Knowledge of petrotechnical, energy, or industrial IoT domains. Experience with identity and access management (Okta, VIDM, SSO/MFA) as it relates to securing AI APIs. Hands-on scripting experience with Bash, PowerShell, or similar tools for SRE automation tasks. Minimum Qualifications: Minimum qualifications may be acquired through technical schools or equivalent related experience. Candidates having qualifications that exceed the minimum job requirements will receive consideration for higher level roles given (1) their experience, (2) additional job requirements, and/or (3) business needs. Depending on education, experience, and skill level, a variety of job opportunities might be available from the Software Engineer to Senior

This is a hands-on software engineering role. We are looking to recruit an experienced Software Engineer to design, develop, and modernize high-performance Rock Physics desktop and cloud applications. Reporting to the Team Lead and working closely with the Product Owner, you will own the technical direction of production software — writing code daily, reviewing pull requests, and driving architectural decisions. Key Responsibilities Design & build software — Architect, implement, and maintain complex desktop and cloud applications using modern software engineering practices (design patterns, SOLID principles, automated testing, continuous integration/delivery).  Modernize legacy systems — Lead migration of mature C/C++ codebases to modern languages, runtimes, and UI/UX frameworks while preserving scientific accuracy and performance. Leverage AI-assisted development — Actively adopt AI-powered tools (e.g., Copilot, code-generation, automated testing assistants) to accelerate delivery and improve code quality. Collaborate on architecture — Partner with the Team Lead and Product Owner to translate requirements into sound, maintainable technical solutions the team can implement and iterate on. Communicate clearly — Escalate risks, trade-offs, and progress in a timely, structured manner to technical and non-technical stakeholders. Stay current — Continuously evaluate and adopt emerging languages, frameworks, cloud services, and AI/ML tooling relevant to the product. Required Qualifications  3+ years of professional software engineering building and shipping complex, production-grade applications — not solely scripting, prototyping, or research. Strong proficiency in C/.NET; and also C/C++; demonstrated ability to work across both languages in a single product ecosystem. Undergraduate (or higher) degree in Computer Science, Software Engineering, or a closely related engineering discipline.  Comfort and curiosity with AI-assisted development tools and a track record of staying ahead of technology trends. Experience with cloud architecture (AWS, Azure, and/or Google Cloud). Proven experience with software engineering fundamentals: object-oriented and component-based design, design patterns, unit/integration testing, version control (Git), and code review workflows. Hands-on CI/CD experience — building, configuring, or maintaining automated build and deployment pipelines. Experience modernizing legacy software — migrating codebases from older languages or frameworks to current platforms, including UI/UX modernization. Self-motivated and collaborative; thrives in a team environment and takes initiative without direction. Excellent analytical, communication, and problem-solving skills.
