Job Summary

The Infra-Dev team builds the software that runs Netradynes cloud infrastructure. We write the internal platforms, automation and AI agents that DevOps, Database and engineering teams use every day: cloud cost analytics and anomaly detection, self-service service provisioning on AWS, an internal developer platform on Kubernetes, database access and upgrade automation, S3 data lifecycle and retention, and agentic tooling for infrastructure operations and on-call.

We are looking for a Senior Staff Engineer to provide technical leadership for Infra-Dev. You will own the teams technical goals and major platforms, decide how new initiatives are approached, and stay hands-on in design and code. You bring wide-ranging experience across cloud infrastructure, software engineering, databases and cost management, and you understand how these disciplines affect one another.

Role and Responsibilities

• Act as technical owner and architect for Infra-Devs major platforms: the cloud operations and cost platform, the service provisioning tooling, the internal developer platform and infrastructure AI agents.
• Lead the design and delivery of multi-quarter initiatives such as containerising services onto Kubernetes (EKS), GitOps-based internal developer platforms, an infrastructure registry of service and resource dependencies, and infrastructure-as-code standardisation.
• Decide the methods, tools and standards for new assignments, including build-vs-buy evaluations, technology selection and migration plans.
• Lead cloud cost management (FinOps) engineering: cost allocation and unit economics (for example, cost per device or per feature), forecasting, anomaly detection, Savings Plans and Reserved Instance coverage, and COGS/OpEx reporting for engineering and finance leadership.
• Act as a technical point of contact for Finance and cloud vendors (AWS account and TAM teams, tooling vendors) on cost analysis, forecasts, commitments and renewals.
• Own the architecture of data lifecycle and storage-cost programs for petabyte-scale S3 data: retention policies, storage-class transitions, data retirement and safe deletion with customer-specific exceptions.
• Run the teams recurring cost and operations reviews, turning findings into prioritised engineering work and measurable savings.
• Define the architecture for agentic infrastructure operations: triage and on-call agents, MCP gateways and human-in-the-loop approvals, with clear security guardrails.
• Set standards for database and access automation across PostgreSQL, MongoDB, Cassandra, OpenSearch, ClickHouse and DynamoDB, working closely with the Database team.
• Provide architecture guidance on shared infrastructure that DevOps and Database teams depend on, including logging pipelines, internal PKI and certificates, Kubernetes secrets management and device-to-cloud ingestion (IoT, Kinesis Video Streams).
• Drive security and compliance-by-default in infrastructure tooling: least-privilege IAM, credential lifecycle, secrets management, tagging and audit reporting.
• Lead architecture and design reviews, RFCs and technical decisions for Infra-Dev, and review designs from DevOps and Database teams where they intersect.
• Identify and address scalability, reliability, cost and security risks across the infrastructure stack before they become incidents.
• Lead investigation of complex production issues that cross application, database, network and cloud layers, and drive lasting fixes.
• Plan sprints and roadmaps with engineering leadership: break down work, manage dependencies, track delivery and report progress with team metrics.
• Make sure critical knowledge is written down: design documents, runbooks and ownership maps for every system the team runs.
• Mentor and grow engineers through design guidance, code reviews and career coaching.
• Take part in hiring, interviews and onboarding for the Infra teams.

Essential Skills

• 8+ years of hands-on software engineering experience, including significant experience building infrastructure, platform, DevOps or SRE software at scale.
