⚡Tria Group Company (as a part of Wise Wolves Corporation) is looking for Systems Administration Manager (50% Hands-On)

📌 Location: OnSite/Hybrid Cyprus Limassol Office

📌 Teams you’ll lead: IT Support (2–3), Systems Administration (2–3)
Partners: DevOps, Security, Compliance

❣️ About us
We’re a software company with our own fintech/crypto custody stack, client apps in the cloud, and a lean bare-metal footprint. We’re hiring a leader who grew up as a senior Linux/infra admin (clusters, physical servers, virtualization, cloud) and now wants to lead people and processes—without giving up real engineering work.

📌 The role (who it’s for)
You’ve been the go-to admin for Linux clusters, hypervisors, networks, and cloud accounts. You love clean infrastructure and solid ops. You’re ready to own IT Support + Systems Admin, implement compliance and controls, and still spend half your week hands-on solving hard infra problems.

📌 What you’ll do
- Lead & grow a small team: Coach 2–3 IT Support and 2–3 SysAdmins; set standards, run 1:1s, guide careers.


- Stay hands-on (~50%): Troubleshoot complex Linux/network issues, upgrade clusters, tune storage/virtualization, and unblock the team.


- Raise service quality: Define SLAs, streamline triage, publish a service catalog, and build self-service/runbooks for common requests.


Core infra ownership:


Linux fleets, hypervisors (KVM/Proxmox/VMware), storage (ZFS/NAS), backups/restore drills.


Office/LAB networks, Wi-Fi/VLANs, VPN (e.g., WireGuard), DNS/DHCP, firewalls.


Identity/SSO (OIDC/SAML), MFA, RBAC, and joiner-mover-leaver automation.


- Cloud & platform: Own org/IAM guardrails and connectivity; partner with DevOps on shared tooling (runners, registries) without taking on app-level pipelines.


- Compliance enablement: Implement practical controls for ISO 27001/SOC 2/EBA/CySEC (asset inventory, access reviews, change logs, DR evidence).


- Security partnership: Operate EDR/vuln management on endpoints/servers; keep PKI/TLS lifecycle healthy with Vault/HSM owners.


- Operations excellence: Incident response for corp IT, crisp RCAs, vendor/license/hardware lifecycle, and cost visibility.


📌 What you’ll bring
- 6–10 years in systems administration with deep Linux expertise on clusters and servers.


- Strong hands-on with virtualization (KVM/Proxmox/VMware), storage (ZFS/NAS), networking (VLANs, routing, VPN, DNS, firewalls).


- Cloud org/IAM experience (AWS/GCP/Azure) and security guardrails.


- MDM/endpoint mgmt for macOS/Windows/Linux; SSO (OIDC/SAML), MFA, RBAC; JML automation.


- Automation with Bash/Python and Ansible (Terraform a plus); Git workflows.


- Clear documentation, incident/RCA writing, and a calm, service-oriented mindset.


- Some team-lead or mentoring experience and a strong desire to formalize it.

- Kubernetes basics (just enough to partner with DevOps; this is not a DevOps role).


📌 Why this role
- A clear management path while staying deeply technical.


- Direct impact on reliability, security posture, and developer productivity.


- Modern stack, small empowered teams, supportive engineering leadership.

⚡Tria Group Company (as a part of Wise Wolves Corporation) is looking for Team Lead Engineer — Golang (Custody Platform)

📌 Location: OnSite/Hybrid/remote (strong overlap with Asia/Nicosia, UTC+2/3)

⚡ About us
We build a custody platform for regulated institutions: policy-driven transaction signing, MPC/TEE-based signers, audit-grade eventing, and multi-tenant infrastructure with strict security boundaries. This is a systems role: high-load SaaS backend, correctness-first workflows, hard security constraints, and clear operational ownership (SLOs, observability, on-call maturity).
We’re looking for a Staff Engineer who can design and ship critical platform components in Go, raise the engineering bar, and reliably deliver under real-world constraints (latency, throughput, failures, attacks, audits).

⚡What you’ll do
● Own core backend architecture: lead design for critical services (policy engine, signing orchestration, key lifecycle workflows, custody wallets/accounts, approvals, audit trails).
● Build high-load SaaS systems: multi-tenant isolation, quotas, rate limits, backpressure, concurrency control, and predictable latency under spikes.
● Distributed systems & reliability: idempotency, retries, outbox/inbox patterns, event-driven workflows, saga/state machines, and graceful degradation.
● Security-by-design: least privilege, secret handling, secure service-to-service auth (mTLS/JWT), tamper-evident logs, and audit-ready data models.
● Performance engineering: profiling, load testing, benchmarking, contention analysis, memory/GC tuning, and optimization of hot paths.
● Data & consistency: strong modeling in Postgres (or equivalent), migrations, indexing strategy, partitioning where needed, and clear consistency boundaries.
● Developer productivity & standards: set patterns for Go services, testing strategy, code review quality, and shared libraries; mentor senior engineers.
● Cursor-first workflow: use Cursor for acceleration (refactors, code generation, tests, docs), with disciplined verification, security review, and deterministic outcomes.

⚡Must-have experience
● 8+ years backend engineering, including significant Go (or deep expertise in another systems language + strong Go in recent projects).
● Strong CS fundamentals: concurrency, synchronization, networking, distributed systems, data structures, algorithms, OS basics.
● Proven track record designing high-load, production SaaS (multi-tenant, high availability, incident response, SLOs).
● Hands-on experience with microservices and modern backend stacks: gRPC/HTTP, queues/streams, caching, databases.
● Strong testing discipline: unit/integration/contract tests, testability-first design, deterministic CI.
● Strong observability habits: structured logging, metrics, tracing, debugging production issues end-to-end.
● REQUIRED: regular use of Cursor (or comparable AI coding tool) to speed delivery, with rigorous review, security awareness, and verification.
**
⚡Nice to have**
● Custody / wallets / signing systems exposure (MPC, HSM, TEE, key management, policy/approvals).
● Experience with event streaming (Kafka/NATS/PubSub), exactly-once-ish patterns, replay, and audit/event sourcing concepts.
● Kubernetes + service mesh familiarity; production operations and reliability engineering practices.
● Regulated environment experience (fintech, security audits, compliance-driven engineering).
● Threat modeling and security review participation (abuse cases, attack surfaces, secure defaults).
Soft skills
● Ownership mindset: you ship, you measure, you improve.
● Clear written communication: designs, RFCs, incident write-ups, trade-offs.
● Pragmatic leadership: raises the bar without blocking progress.


⚡What this role is NOT
● Pure feature “ticket execution” without architectural ownership.
● Fullstack work.
● Research-only cryptography role (you’ll collaborate with cryptography specialists, but your focus is platform engineering).
