Role Overview

We are looking for a Senior Cloud Engineer to lead production readiness, secure cloud deployment, and live cutover of a regulated, high‑assurance platform.

This role is critical in ensuring that AWS production environments are secure, compliant, and operationally resilient, with a solid focus on infrastructure as code (Terraform), security controls, key management, and production deployment practices.

You will work at the intersection of cloud engineering, security, and platform operations, supporting a high‑stakes production launch and vendor integrations.

Key Responsibilities

- 1. Production Environment Setup & Governance
- Establish and configure AWS production environments (ca-central-1) separated from non‑production accounts.
- Implement multi‑account governance and federation models aligned with enterprise standards.
- Apply infrastructure‑as‑code (Terraform) modules to enforce:
- Service Control Policies (SCPs)
- Data residency controls
- MFA enforcement and root access restriction
- Public access protections (e.g., S3 hardening)
- Configure monitoring, alerting, and centralized logging using CloudWatch and log aggregation solutions.

- 2. Security & Key Management Infrastructure

- Implement and manage customer‑managed KMS keys, including asymmetric key configurations.




- Deploy and maintain secure key custody frameworks, including:
- Application service keys (rotating)
- Blockchain validator keys
- Privacy/encryption keys for sensitive transaction layers

- Ensure secure handling of secrets via AWS Secrets Manager with automated rotation.

- 3. CI/CD & Production Deployment

- Activate and manage production CI/CD pipelines with environment gating and approvals.
- Deploy applications and infrastructure using controlled release mechanisms.
- Lead production deployments of pre‑validated components (from dev & staging) including:
- Encryption and signing mechanisms
- Security‑sensitive platform components

- 4. Production Readiness & Runbook Validation

- Validate and refine production runbooks against real‑world system behaviour.
- Identify and address gaps between staging and production environments.
- Ensure operational readiness, incident response alignment, and monitoring coverage.

- 5. Vendor Integration & Cutover

- Own the end‑to‑end integration and production cutover of critical third‑party services.
- Transition from mock sandbox to production for:
- KYC systems (e.g., Persona)
- Compliance platforms (e.g., sanctions, PEP screening)




- Custody / MPC platforms (multi‑party computation)

- Ensure secure data flows and operational stability.

- 6. Hypercare & Production Support

- Support live production cutover and stabilization phases.
- Monitor platform health, performance, and security posture.
- Rapidly respond to incidents during hypercare period.

Required Skills & Experience

- 7+ years in cloud engineering / platform engineering roles.
- Strong hands‑on experience with AWS (multi‑account environments).
- Deep expertise in Terraform (modular design, IaC best practices).
- Proven experience implementing:
- Cloud security frameworks (IAM, SCPs, KMS, Secrets Manager)
- Monitoring & observability (CloudWatch, logging pipelines)

- Experience with CI/CD pipelines and controlled production deployments.
- Strong understanding of:

- Production readiness and release management
- Secure architecture and data protection controls

- Experience supporting high‑risk production cutovers or regulated environments.

Nice to Have

- Experience with blockchain or cryptographic key management systems.
- Exposure to MPC (multi‑party computation) or custody platforms.
- Familiarity with compliance/KYC integrations.
- AWS certifications (Solutions Architect / DevOps / Security).

What You Bring

- Ownership mindset with ability to lead production‑critical initiatives.
- Strong problem‑solving skills in high‑pressure environments.
- Ability to work across engineering, security, and vendor teams.
- Clear communication and documentation skills.
