The posting

Drive end-to-end network projects for R&D—from architecture to execution across branch networks, private networks, and AWS connectivity.

  • This position is responsible for designing and operating the branch networks, private networks, on-premises infrastructure, and AWS connectivity that support our R&D and office environments.
  • While this is not a Cloud SRE role, AWS networking is within your scope. You will primarily focus on on-premises and private networks, while expanding your coverage to the entire network architecture, including AWS.
  • Your responsibilities will range from requirements definition and equipment sizing for new branch setups to configuration changes, troubleshooting, and end-to-end project execution.
  • We welcome candidates from either background—whether you come from an on-premises network background looking to expand into AWS, or from a cloud background looking to broaden your scope into on-premises infrastructure.

研究開発を支える拠点ネットワーク・閉域網・AWS接続を、設計からプロジェクト推進まで。

  • 研究開発環境およびオフィス環境を支える、拠点ネットワーク・閉域網・オンプレミス基盤・AWS接続を設計・運用するポジションです。
  • クラウドSREのポジションではありませんが、AWSネットワークも担当領域に含まれます。オンプレミス/閉域網を中心に担当し、AWSを含むネットワーク全体へ担当領域を広げていただきます。
  • 拠点追加時の要件定義・機器サイジングから、設定変更、トラブルシューティング、プロジェクト推進まで担っていただきます。
  • オンプレミスネットワークを軸にAWSへ広げていく方も、クラウド基盤を軸にオンプレミスへ広げていく方も、どちらも歓迎しています。

Background

Specialized expertise is required for our private networks and on-premises infrastructure. To ensure we retain critical knowledge—such as system architecture, technical know-how, and vendor management—in-house rather than relying solely on temporary staff, we are looking to bring on a full-time employee to own this domain.

Additionally, relying entirely on vendor requests often fails to deliver the speed we need. In practice, this role involves directly making configuration changes on-site when required.

募集背景

閉域網・オンプレネットワークについては専門性が必要です。派遣メンバーだけでなく、社内に技術・構成・ベンダーコントロールの知識を蓄積する意味でも、正職員として担っていただける方をお迎えします。

尚、ベンダーへの依頼ベースでは必要なスピードが確保できないことがあり、実際には現場で設定変更まで行っている状況です。

Main Duties

  • Internal & Branch Networks: Design and operate internal LANs, branch networks, and private networks (closed networks).
  • Network Planning & Requirements: Define network requirements for new office setups, relocations, and floor expansions.
  • Architecture & Sizing: Determine hardware configurations and equipment sizing based on user count, device count, traffic volume, required bandwidth, port density, PoE requirements, redundancy, and wireless AP density.
  • L2/L3 Network Management: Design and operate Layer 2 and Layer 3 networks.
  • Network Configurations: Configure and maintain VLANs, routing protocols, and firewall rules.
  • Network Device Management: Hands-on operation and management of FortiGate and Cisco Meraki hardware.
  • AWS & Hybrid Connectivity: Design and review connections between on-premises / private networks and AWS network components (VPC, Subnet, Route Table, Security Group/NACL, VPN, Direct Connect, etc.).
  • Troubleshooting & Incident Response: Perform network troubleshooting and manage incident response.
  • Vendor Management: Coordinate with telecom carriers and network vendors.
  • Project Management: Plan and manage network projects, including tracking issues, monitoring progress, and coordinating across stakeholders.
  • On-Premises Systems Operation: Manage on-premises infrastructure, such as Linux servers and NAS storage.
  • Documentation: Create and maintain network topology diagrams and standard operating procedures (SOPs).
  • Security & Governance: Design and operate networks with a strong focus on information security best practices.

主な業務

  • 社内LAN/拠点ネットワーク/閉域網の設計・運用
  • 拠点新設・移転・増床等におけるネットワーク要件定義
  • 利用人数、端末数、通信量、必要帯域、ポート数、PoE、冗長性、無線AP数等を踏まえた機器構成・サイジング
  • L2/L3ネットワークの設計・運用
  • VLAN、Routing、Firewall等の設定・運用
  • FortiGate/Merakiの運用
  • AWSネットワーク(VPC、Subnet、Route Table、Security Group/NACL、VPN、Direct Connect等)とオンプレミス/閉域網の接続設計・レビュー
  • ネットワーク障害対応、トラブルシューティング
  • 通信キャリア、ネットワークベンダーとの調整
  • ネットワークプロジェクトの計画、課題・進捗管理、関係者調整
  • オンプレミスLinuxサーバ、NAS等のストレージの運用
  • ネットワーク構成図、運用手順書の管理
  • セキュリティを考慮したネットワーク設計・運用

【Why Join Us / Role Highlights】

  • Beyond the Cloud (Hybrid Expertise):Unlike pure cloud-native companies where physical infrastructure exposure is limited, our setup combines on-premises systems, networking, private networks, Linux, storage, public cloud, and SaaS. Developing expertise across both cloud and on-premises environments makes your skill set uniquely valuable in today’s market.
  • Build & Shape Phase:You will do more than just maintain existing operations—you have the autonomy to rebuild, optimize, and improve the underlying systems and processes themselves.
  • Powering AI & Robotics R&D:You will directly build and support the critical infrastructure that empowers AI researchers, robotics engineers, and software developers.
  • Direct Ownership & Technical Depth:This is not a vendor-management-only role. You will have a hands-on environment where you can dive deep into network design and make direct configuration changes yourself.
  • Full Ownership & Project Leadership:Beyond day-to-day operations, you will be expected to drive network projects from end to end and take full ownership of our network domain.

【仕事の醍醐味】

  • クラウドだけではない:
  • クラウドネイティブ企業では触れる機会が減っている、オンプレミス、ネットワーク、閉域網、Linux、ストレージ、クラウド、SaaSが共存しています。次のキャリアを考えたときに「クラウドもオンプレもできる」という経験は、今の市場では希少です。
  • 立ち上げフェーズ:
  • 既存運用を回すだけではなく、仕組みそのものを改善できます。
  • AI・ロボティクス研究開発を支える情シス:
  • AI、ロボティクス、研究者、ソフトウェアエンジニアの仕事を支えるインフラに関われます。
  • 自分の手で動かせる:
  • ベンダー任せではなく、設計・設定変更まで自分で踏み込める環境です。
  • 将来は完全に任せる:
  • ネットワーク領域は、運用だけでなくプロジェクトの推進まで担っていただく想定です。

Requirements

Required Qualifications:

We welcome candidates matching either Profile A or Profile B below:

[Profile A] On-Premises Network Specialist

  • Strong foundational knowledge of networking concepts (TCP/IP, Routing, VLANs, etc.).
  • Hands-on experience designing and operating L2/L3 switches, routers, and firewalls.
  • Proven track record in network troubleshooting and issue isolation.
  • Operational experience with on-premises environments (Linux servers, NAS storage, etc.).
  • Experience coordinating with telecom carriers and network vendors.
  • Ability to design and operate networks with a security-first mindset.
  • Willingness to learn existing architectures upon joining and expand your scope to AWS design, modification, and testing.

[Profile B] Cloud Infrastructure Specialist

  • 1.5+ years of practical experience with AWS or Google Cloud infrastructure.
  • AWS or Google Cloud certification (Associate level or equivalent).
