Arcesium - Senior Linux Engineer in Hyderabad, भारत

We are looking for someone who will own the architecture and health of the Linux side of Developer Compute - the fleet of AWS WorkSpaces, WSL, and Linux config that thousands of engineers build on every https://jobeax.com/link/2ClVtuvxr8597N3Q'll set the standard for how the team ships Ansible changes through peer review, do the deep OS-internals work that keeps the fleet healthy, and act as the final technical authority when a problem survives first-line and self-service https://jobeax.com/link/qYxw2y6jr11Z11Sg is a hands-on senior Unix engineering role: you diagnose from strace and journalctl, design the fix at the platform level, and make sure it's codified so the same problem doesn't recur across the https://jobeax.com/link/WMrb5Ww6UgeXb6oW Role at a Glance:- Architect and own the Linux compute platform - the design decisions behind AWS WorkSpaces, WSL, and the broader Linux fleet that thousands of engineers build on daily.- Set the automation standard: define how configuration, patching, and lifecycle management are codified in Ansible and enforced through engineering review, not just author individual changes.- Act as the final technical authority on hard Unix/identity/infrastructure problems - the ones that survive first-line and self-service troubleshooting.- Drive the platform's technical roadmap: OS/region expansion, deprecation of legacy images, and R&D into Unix-ecosystem capabilities the fleet doesn't yet https://jobeax.com/link/lSldL9cusF4jEiKH You'll Do:- Resolve fleet-wide health issues at the root: Investigate unhealthy/stuck/disconnecting WorkSpaces reported daily by end users - stale desktop-session state, broken shell config after a distro migration, disk/memory exhaustion, CloudWatch-reported anomalies - and fix the underlying cause via Ansible rather than a one-off reboot.- Own Ansible for the Linux/WorkSpaces fleet: Author and review playbooks and roles covering package management, DNS/nameserver config, credential-refresh scripts, PAM/Kerberos, and systemd-based job scheduling; land changes through a peer-reviewed merge-request workflow with staged rollout and a rollback plan.- Troubleshoot auth and identity plumbing: Debug Kerberos/KCM cache issues, kinit failures, GSSAPI/publickey SSH auth errors, and STS regional-endpoint assumptions across accounts - the kind of problems that show up as "VSCode SSH won't connect" but trace back to credential caches or IAM endpoint config.- Keep package management and toolchains working: Own issues across modern and traditional Linux package managers and internal package repositories - SSL/cert trust issues, GPG signature failures, repository-trust enforcement changes - so day-to-day package installs keep working across every supported distro and macOS/WSL.- Support new region and OS rollouts: Help stand up new WorkSpaces regions and new OS bundles (e.g. newer Ubuntu/Rocky Linux releases) - directory setup, bundle config, lifecycle automation, and portal integration - and lead migration paths off end-of-life images.- Build observability, not just fixes: Extend monitoring for Ansible run failures and workspace health so issues surface as alerts before they become a wave of support requests; contribute to diagnostic tooling that lets users self-service common problems.- Debug container and dev-tool issues on the fleet: Resolve container networking-at-boot failures, credential-in-container breakage, dev container support, and IDE/SSH integration issues that block engineers mid-task.- Set the platform standard and mentor: Define how root-cause fixes get codified into Ansible and documentation rather than repeated as generic advice; raise the technical bar of the wider team and be the reference point for how hard Unix problems get diagnosed and closed out https://jobeax.com/link/DnbXxa7FOifkOcrZ You'll Need:- Experience: 5 - 8+ years in Linux systems engineering, with real ownership of production Linux fleets - not just following documented procedures.- AWS WorkSpaces / VDI depth: Hands-on experience operating and troubleshooting AWS WorkSpaces (or equivalent Linux VDI) - directory integration, bundle/image lifecycle, region rollouts, connectivity and performance diagnosis (WSP protocol, CloudWatch metrics).- Advanced Unix/Linux fundamentals: Comfortable reasoning about systemd, PAM, Kerberos/KCM credential caches, SSH auth mechanisms (publickey, GSSAPI), filesystem/permission issues, and using strace/journalctl/perf to get from symptom to root cause not just restarting the service.- Ansible in production: Strong hands-on Ansible - playbooks, roles, idempotency, staged rollout - and comfort working through a peer-reviewed merge-request workflow with CI as the primary way changes reach the fleet.- Package ecosystem knowledge: Familiarity with Linux package managers across distros (apt/dnf), Homebrew, and modern declarative package/environment managers (e.g. Nix-based tooling) - including the cert-trust, GPG-signing, and repo-config issues that come with managing them at fleet scale.- R&D mindset: A track record of independently digging into unfamiliar problems (e.g. AWS/Rocky Linux bug backports, kernel-level networking issues) rather than waiting for someone else to hand you a fix.- Cloud & directory services foundation: Solid AWS fundamentals (IAM, STS, VPC networking) and enough Active Directory/Kerberos literacy to debug identity issues that span the two.- Communication under pressure: Able to work a live escalation with a blocked engineer without guessing - diagnose, explain, and close the loop; comfortable being the person others turn to when first-line steps don't work.- Education: Bachelor's in Computer Science, Engineering, or related field; equivalent hands-on experience https://jobeax.com/link/KKx2FSOED0mzIPE5's Personal Data Privacy Notice for Candidates is linked.
