What We’re Looking For:

As the Senior Manager of Cybersecurity Operations, you will lead and mature 2U’s global cyber defense and security operations capabilities. This role is accountable for the effective execution of threat detection, incident response, vulnerability management, and operational security monitoring across a global enterprise.

You will manage and develop a team of security engineers responsible for day-to-day security operations, while also acting as the operational bridge between cybersecurity engineering, infrastructure, SRE, IT, and external partners (including managed or embedded resources). While remaining technically credible, your primary focus will be on operational excellence, incident readiness, process maturity, and ensuring consistent, high-quality execution of security operations at scale.

This role requires strong leadership, sound judgment under pressure, and the ability to translate technical security events into clear risk-based communication for senior stakeholders. You will own operational outcomes, ensure alignment to industry frameworks, and continuously improve tools, processes, and team capability to reduce risk across 2U’s most critical systems.

Responsibilities Include, But Are Not Limited To:

Cybersecurity Operations & Execution

• Own and oversee day-to-day cybersecurity operations, ensuring effective threat detection, investigation, response, and remediation across cloud, application, and infrastructure environments.

Security Operations Coverage & Readiness

• Ensure cybersecurity operations maintain effective visibility and response capability across cloud, infrastructure, and application environments, aligned to defined risk and threat models.
• Oversee the integration of logging, telemetry, alerts, and response playbooks into operational tooling (e.g., SIEM, SOAR, EDR), without assuming ownership of underlying platform or application architectures.
• Partner with domain security teams to validate that new systems, services, and changes are adequately covered by operational security monitoring and incident response processes.
• Continuously assess and improve operational coverage to ensure cybersecurity operations can detect, respond to, and support incidents across the evolving technical environment.

Proactive Risk & Vulnerability Management

• Ensure security findings and risk trends are translated into clear, actionable insights for technical and non-technical stakeholders.

Team Leadership & Partner Management

• Lead, mentor, and develop cybersecurity operations engineers, fostering a culture of accountability, continuous improvement, and operational excellence.
• Provide direction and oversight to embedded or partner resources (e.g., Sonata), ensuring clear expectations, quality delivery, and alignment to 2U standards.
• Contribute to workforce planning, skills development, and operational maturity of the cybersecurity operations function.

Things That Should Be In Your Background:

• 5+ years experience in cybersecurity or security operations, with progression into technical leadership or people management.
• Experience leading or supporting security operations, incident response, or threat management in complex environments.
• Working knowledge of AWS; exposure to GCP or Azure is a plus.
• Comfortable with scripting/automation (e.g., Python, Bash) to guide and review operational improvements.
• Experience partnering on CI/CD and DevSecOps initiatives to ensure security signals feed into detection and response.
• Familiarity with cloud-native and containerised environments and their operational security risks.
• Required: Hands-on experience with SIEM and EDR platforms supporting security monitoring, investigation, and incident response.
• Beneficial: Experience with SOAR workflows and WAF technologies to support security automation and application protection.
• Strong analytical judgment, able to make risk-based decisions under pressure.
• Clear communicator with both technical teams and senior stakeholders.

About us:

Luno is the crypto investment app you can rely on, enabling you to buy, store and explore crypto securely. We’re committed to putting the power of cryptocurrency in everyone's hands sensibly and responsibly.

About the team:

The Platform SRE team at Luno owns the full infrastructure stack - from Kubernetes and AWS through to CI/CD, observability, networking, and developer tooling. We work with high autonomy, balancing business initiatives, platform improvements, and the reliability work that keeps a global financial platform running.

Your Role at impact.com:

impact.com's Analytics Data Platform processes terabyte-scale data for one of the world's leading partnership SaaS platforms, covering the full lifecycle from ingestion to governed access.

We're looking for a technical people leader to own and grow the Data Platform Engineering team, while driving the architecture, reliability, and evolution of impact.com's Analytics Data Platform. This is a senior player-coach role: you'll combine hands-on technical leadership with direct people management, building a high-performing team, owning delivery, and shaping platform strategy. Expect to spend roughly 40% hands-on and 60% on leadership, people, and delivery, shifting as the team matures. You'll be accountable for both the team's output and its people, ensuring engineers are supported, challenged, and growing.

As Team Lead for Data Platform Engineering, you'll work across the full data ecosystem (ingestion, processing, storage, orchestration, access, and governance) using technologies like Scala, Python, Google Cloud Dataproc, BigQuery, and Airflow. You'll shape the operating model for the team, establish engineering standards, and drive platform strategy. This role is levelled at Senior/Staff Engineer on the engineering management track and reports to the Director of Advanced Analytics. The position is based in Cape Town, hybrid, with one day per week in office.

Data Platform Engineering is one of four sub-teams within the Data Analytics Group (DAG). DPE owns ingestion, infrastructure, orchestration, and platform services. Analytics Engineering owns the dbt transformation layer and semantic layer. Data Analytics owns reporting and insights. Data Product Management owns product roadmaps and governance processes. You'll partner closely with all three, but won't own dbt models, reporting, or product prioritisation directly.

Our ideal candidate combines distributed systems expertise with proven people leadership. Someone who can make architecture decisions, run a team, and translate platform trade-offs into business language. This role is for someone who wants to build both a platform and a team, not just maintain what exists.

What you'll inherit:

The platform has strong foundations: Scala/Spark pipelines processing TB-scale data, 37+ Fivetran connectors, Airflow on Astronomer for orchestration, a mature dbt-based transformation layer, and BigQuery as the core analytical warehouse. Databricks is part of the current stack but is being transitioned off in favour of Dataproc and BigQuery-native patterns. What's greenfield: governance frameworks, data contracts, SLOs/SLAs, observability, cost management, and data quality monitoring. You'll build the team that delivers on these opportunities.

What you'll do:

• Build and run a team of data platform engineers: set direction, remove blockers, give honest feedback, and make sure people are growing in their careers.
• Create an environment where engineers do their best work: high trust, high standards, low friction.
• Turn platform strategy into a delivery plan the team can actually execute: sequence the work, balance new builds against keeping the lights on, and make the trade-offs visible.
• Own capacity and priorities across the team. Keep cross-team dependencies from becoming bottlenecks.
• Lead platform architecture decisions, design reviews, and cross-org technical coordination, defining and promoting architectural patterns, standards, and guidelines.
• Design and implement scalable pipelines using Scala, Python, and distributed frameworks (Spark on Dataproc) processing TB-scale data. Lead the migration off Databricks onto Dataproc and BigQuery-native patterns.
• Establish platform reliability practices: define SLOs/SLAs, build incident management and response processes, and drive systemic improvements across pipeline and infrastructure operations.
• Design and maintain core platform services (Dataproc clusters, BigQuery datasets, Cloud Storage) and optimise platform performance and cost at scale.
• Build and operationalise data governance, security, and compliance capabilities, including data contracts, access controls, and audit logging. Many of these practices are greenfield; you will be building them from scratch.
• Define and evolve team rituals, operating cadences, and engineering standards: code review norms, documentation practices, on-call fairness, and knowledge sharing.
