About Papers

Papers is a software engineering company founded on high-tech talent. We support the full lifecycle of innovative web3 products — from concept to software market fit — building secure, scalable futures for our clients and the internet at large.

With over a decade of experience and a reputation built on delivering for Fortune 500s and blockchain ecosystems, our teams combine deep technical know-how with a mission to enable meaningful, decentralized innovation.

As an engineering-driven team, we work with autonomy and purpose. Our culture is built on meritocracy, long-term thinking, and a commitment to quality over buzz. We aim to collaborate with people who love tech for its own sake and want to help shape the future by solving real-world challenges.

Tasks

Your Responsibilities

  • Manage and improve our self-hosted, Linux-based infrastructure (Ubuntu) running on a fleet of dedicated/bare-metal servers

  • Keep servers patched and up to date (OS/security updates, reboots) and maintain the various applications we self-host

  • Administer Microsoft 365 / Entra ID (Azure AD) — identity & access management, MFA, Conditional Access, SSO, and email/collaboration security

  • Own and continuously improve our security posture: SSH/host hardening, firewalls, secrets management, least-privilege access, periodic access reviews, and incident response

  • Participate in on-call rotations to support critical services (incl. the Acurast blockchain/bridge infrastructure)

  • Collaborate with backend engineers to streamline integration and delivery

  • Continuously identify and automate repetitive tasks to reduce manual intervention
