Position Overview

As the energy sector undergoes rapid digital transformation, demand for our services continues to grow. To support the next phase of our platform and product expansion, we are looking for a Senior Cloud Engineer (Azure) to help build, operate, and scale the cloud foundation behind our services.

This role goes beyond traditional infrastructure operations. As a startup, we need an engineer who can combine cloud engineering, SRE, and platform engineering perspectives—someone who can design robust Azure infrastructure, improve developer workflows, and take ownership of non-functional requirements such as reliability, observability, scalability, security, and cost efficiency.

You will work closely with application engineers and business stakeholders to support systems that power critical energy services in Japan.

Responsibilities

You will be responsible for the design, implementation, and operation of Bluefield Energy’s cloud infrastructure and shared platform capabilities. Depending on your experience and interests, your responsibilities may include:

Design, build, and operate cloud infrastructure on Microsoft Azure
Develop and maintain Infrastructure as Code, primarily with Bicep, and leverage equivalent experience with tools such as Terraform where relevant
Build shared platform components, templates, and operational foundations that improve engineering productivity
Establish and improve SRE practices, including monitoring, logging, alerting, incident response, and operational readiness
Improve system reliability, scalability, performance, security, and cost efficiency in production environments
Design and improve CI/CD and deployment workflows using GitHub Actions and related tooling
Partner with software engineers to support cloud-native architecture and smooth service delivery
Troubleshoot production issues and drive continuous operational improvement
Proactively define and improve non-functional requirements across systems and services

Why Join Us

Work on socially impactful products in the rapidly growing EnergyTech market
Help build the cloud foundation for services that support critical energy infrastructure in Japan
Take ownership across cloud engineering, SRE, and platform engineering in a startup environment
Work deeply with Microsoft Azure and modern IaC practices centered around Bicep
Join a high-caliber team and contribute directly to product and platform decisions

Ideal Candidate Profile

Self-motivated and comfortable taking ownership in an ambiguous startup environment
Strong systems thinker who can balance speed, reliability, and maintainability
Interested not only in infrastructure, but also in improving developer experience and operational excellence
Able to think beyond functional requirements and proactively design for observability, reliability, and scalability
Comfortable collaborating across technical and non-technical teams in both Japanese and English
Eager to continuously learn and apply new technologies and design approaches

Required Skills and Experience

5+ years of professional experience in cloud infrastructure, DevOps, SRE, platform engineering, or closely related roles
Strong hands-on experience building and operating systems on Microsoft Azure
Experience with Infrastructure as Code, ideally Bicep, or equivalent experience with Terraform
Experience designing, building, and operating production systems with reliability and operational excellence in mind
Solid understanding of monitoring, logging, alerting, and incident response
Ability to communicate in conversational Japanese (basic daily communication required)

Preferred Skills and Experience

Microsoft Azure certifications
Experience with GitHub Actions
Experience designing or operating large-scale systems
Experience owning or improving non-functional requirements such as observability, scalability, fault tolerance, and performance
Programming experience in C#, Python, or other backend / scripting languages
