[About the Role] As a Platform / SRE Engineer, you will bridge software engineering, infrastructure excellence, and comprehensive system visibility. The Infrastructure & Platform team provides the secure, observable, and reliable cloud foundation used by ENEXIA's software, data, and ML systems. This is a hands-on IC role for a builder with the grit to decouple, refactor, and reorganize legacy, vendor-dependent systems — spearheading a modern observability stack and the foundational infrastructure required to run autonomous AI agents and workflows with full transparency.
Responsibilities:
Architect advanced observability (metrics, logs, traces, dashboards, proactive alerting, SLOs, incident learning) to eliminate blind spots with actionable data.
Decouple legacy systems, networks, and security: investigate, reverse-engineer, and incrementally refactor vendor-dependent environments into modern cloud architectures.
Build secure, reusable cloud-platform modules and self-service capabilities via modular IaC and software tooling.
Design secure cloud network topologies, VPC, secrets, access controls, and platform guardrails (IAM, network isolation) for production energy systems.
Design an AI-augmented incident-management system across detection, triage, investigation, remediation, communication, and post-incident learning.
Develop reliable internal tools, integrations, exporters, and self-service automation in Go (and Python where it fits).
Builder mindset and ownership: assessing ambiguous infrastructure with stakeholders, building custom integrations, releasing production-ready solutions; a track record of staying with an organization to solve long-term technical debt.
4+ years in platform engineering, SRE, DevOps, cloud infrastructure, or a closely related production role.
Ground-up experience building and operating observability/telemetry platforms (Grafana, Prometheus, Alertmanager, or GCP Operations Suite).
Hands-on production cloud environments; GCP strongly preferred, strong AWS with the ability to cross-train also considered.
Production-level IaC and containers (Terraform/Terragrunt, Docker) with modern CI/CD.
Production-level Go for reliable tools, custom exporters, or internal self-service automation.
Strong foundations in cloud networking, IAM, security controls, secrets, and least-privilege access.
Experience diagnosing ambiguous cross-system production problems through to durable resolution (leading incident response, reliability, or operational transformation).
Strong collaboration and influence: facilitating discussions, explaining trade-offs, building consensus, documenting and teaching.
Ability to distinguish work safely delegated to AI/automation from decisions needing rapid human judgment, accountability, and escalation.
[Who We're Looking For / Culture] We are building the engineering team, not joining one that already exists. ENEXIA was founded about two years ago and is bringing core engineering capabilities in-house, so there is real room to shape the team, its practices, and the systems it owns.
Uses AI as far as it will go, but holds a high standard for what happens after the model returns an answer — understanding, testing, and reviewing output, and putting their own name behind it. Judgment, decisions, and accountability stay human.
Treats leadership as a way of working, not a title: looks beyond their domain, identifies problems without waiting for instructions, involves the right people, and moves work forward.
When they see an architectural or operational issue, investigates hands-on and builds a prototype or demonstration rather than only discussing it.
Brings curiosity and adaptability, challenges existing assumptions (including our own), and turns ambiguity into concrete action.
Shares knowledge rather than protecting it individually.
