Job description

About Complexio

Complexio is the intelligence layer for enterprise AI. Our platform builds a connected understanding of how businesses actually operate - across people, processes, and systems.

Enterprises have invested heavily in AI platforms, copilots, and data infrastructure - yet daily work still runs on manual hand-offs and thousands of unseen tasks buried in emails, chats, and spreadsheets. Complexio closes that automation gap.

Our Event Knowledge Graph ingests structured and unstructured data to create a living map of how an organisation truly works - every task, interaction, and dependency. Our Context Broker unifies this knowledge across enterprise systems in real time, enabling our Orchestration layer and Enterprise Automator to discover, design, and execute workflows autonomously. Stevie, our conversational AI assistant, gives teams a natural way to query and act on that intelligence.

Complexio deploys securely within your infrastructure and integrates with the enterprise platforms you already run on - turning organisational knowledge into measurable business outcomes.

A joint venture between Hafnia and Símbolo, backed by leading maritime partners including Marfin Management, C Transport Maritime, Trans Sea Transport, and BW Epic Kosan. Born in maritime, now scaling rapidly across industries.

We are now onboarding enterprise customers globally, with a platform built to handle the pace and complexity of real business operations.

About the role:

We’re looking for an Operations Team Lead to own production. Not just keep it running, but build a system that scales.

You’ll lead operational excellence across all live customer-facing systems. Your mission: make production reliable, observable, predictable, and continuously improving.

This is a hands‑on role. You’ll shape process, lead incidents, build the team, and move us from reactive firefighting to proactive reliability engineering.

What You’ll Own

Production

• Stability and availability of all live systems
• Operational readiness for new releases
• Safe production access and change coordination

Production is a high-discipline environment. You make sure it stays that way.

Incident Management

You own the full lifecycle:

• High‑signal alerting and fast detection
• Structured incident response
• Clear internal and customer communication
• Blameless postmortems
• Systemic fixes that prevent repeats

Goal: Fast recovery. Fewer recurring incidents.

On‑Call

• Design sustainable rotations
• Clear escalation paths
• Defined severity levels
• Strong runbooks
• No burnout culture

Someone accountable is always reachable. Escalations are fast and predictable.

Monitoring & Reliability

• Define SLIs/SLOs for critical systems
• Improve visibility across availability, latency, errors, and saturation
• Track MTTR, incident frequency, and escalation trends
• Drive reliability roadmap initiatives

We measure reliability, and improve it continuously.

Team Leadership

• Lead and grow the Operations team
• Set clear standards and KPIs
• Build a culture of ownership and accountability
• Raise the bar on operational discipline

You’re responsible for both system performance and team performance.

What We’re Looking For

• Strong experience in SRE, DevOps, Infrastructure, or Production Engineering
• Prior experience leading technical teams
• Deep hands‑on incident management experience
• Strong observability and reliability mindset
• Calm under pressure, clear in communication
• Systems thinker, fixes root causes, not symptoms

How We Think

• Production is sacred.
• Clear ownership beats ambiguity.
• Blameless culture, high accountability.
• Fix systems, not people.
• Reliability is a product feature.
