At N-iX, our CTO Group helps clients solve complex technology challenges and turn cloud transformation into measurable business outcomes. We design and deliver modern cloud platforms, application modernization programs, and scalable cloud-native solutions for enterprise clients globally.

We are looking for a Senior Cloud Architect to join our Cloud Solutions team and lead architecture across strategic client engagements.

This is a client-facing architecture role combining cloud strategy, solution design, presales, discovery, and delivery leadership. You will work with clients from early-stage technology discussions and assessments through target architecture and transformation 

roadmaps to successful delivery.

We are looking for strong cloud architects with deep expertise in AWS or Microsoft Azure. You don't need to be an expert in every cloud – strong architecture fundamentals, engineering experience, and the ability to solve complex client problems matter more.

Responsibilities:

• Lead solution architecture across presales, assessments, discoveries, and strategic client engagements.
• Work directly with client stakeholders, including engineering leaders, CIOs and CTOs, to understand business goals and translate them into technology strategies.
• Design scalable, secure, resilient and cost-effective solutions on AWS and/or Microsoft Azure.
• Define target-state architectures and transformation roadmaps for cloud migration, application modernization and cloud-native development.
• Design architectures using modern approaches including microservices, containers, Kubernetes, serverless, APIs and event-driven systems.
• Define cloud platform foundations including networking, identity, security, observability, governance and landing zones.
• Lead technical workshops and architecture discussions with client and engineering teams.

• Perform architecture reviews and help teams resolve complex technical challenges.
• Contribute to N-iX cloud offerings, reference architectures, accelerators and reusable assets.
• Stay current with cloud and AI capabilities and help clients identify where emerging technologies can create practical value.

Requirements:

• 8+ years of experience in software engineering, cloud engineering or architecture roles.
• Strong hands-on architecture experience with AWS or Microsoft Azure.
• Proven experience designing and delivering enterprise-grade cloud solutions.
• Experience with cloud migration, application modernization or cloud-native transformation.
• Strong understanding of distributed systems and modern application architecture.
• Experience with containers and Kubernetes such as EKS or AKS.
• Good understanding of cloud networking, IAM, security, resilience, observability and cost optimization.
• Experience with Infrastructure as Code and modern DevOps/CI/CD practices.
• Ability to move between high-level architecture and detailed technical discussions with engineering teams.
• Experience leading technical workshops, discoveries or architecture assessments.
• Strong communication skills and the ability to explain complex technology decisions to both technical and business stakeholders.
• Upper-Intermediate/Advanced English.

We'd Especially Value:

• Experience across both AWS and Azure.
• Experience leading complex cloud modernization programs.
• Strong software engineering background.
• Experience with platform engineering and developer platforms.
• Experience designing AI/GenAI-enabled solutions using services such as Amazon Bedrock, Azure AI Foundry or equivalent platforms.
• Experience with FinOps, cloud governance and enterprise landing zones.
• Experience mentoring engineers or architects.

Certifications:

Relevant professional-level cloud certifications are an advantage, including:

• AWS Certified Solutions Architect – Professional
• Microsoft Certified: Azure Solutions Architect Expert (AZ-305)
• AWS/Azure DevOps, Security or related certifications
• Terraform, Kubernetes or architecture certifications
• Anthropic Claude Architect or other AI-enabling certifications

Why Join:

You'll work on complex cloud transformation challenges rather than being tied to a single product or project.

You'll have the opportunity to:

• Shape solutions from the first client conversation through delivery.
• Work across industries, architectures and technology stacks.
• Influence technical decisions on strategic enterprise engagements.
• Work with experienced architects and engineers across the N-iX technology organization.
• Build new cloud capabilities, accelerators and offerings.

• Strong hands-on expertise in Python and modern ML frameworks, with the ability to ship, operate, and evolve ML systems in production.
• Solid experience with AWS and MLOps practices, including deployment, monitoring, and operating ML systems at scale.
• Practical experience applying GenAI / LLMs in applied or production contexts, with a clear understanding of trade-offs and limitations.
• Ability to influence technical decisions through clear judgment and collaboration, not formal authority.
• Experience supporting and guiding more junior data scientists through hands-on collaboration, code reviews, and technical feedback.
• Strong sense of ownership and accountability for outcomes, with a pragmatic approach to trade-offs and delivery.
• Excellent verbal and written English skills.

Meta Ads / Paid Social Performance Marketer

About PCM

PCM is a private equity firm that invests in and operates growing businesses across multiple industries, with a significant focus on home services.

We are building out our internal performance marketing capabilities to accelerate lead generation across our portfolio companies. Rather than outsourcing growth entirely to agencies, we want world-class paid media expertise in-house that can develop, test, and scale customer acquisition strategies across multiple businesses and markets.

Our home services portfolio and marketing efforts span verticals such as pest control, roofing, replacement windows, and exterior home improvement.

We're looking for an experienced Meta Ads Performance Marketer who can help us significantly expand these lead generation efforts.

The Role

This isn't simply a media buying position.

We're looking for someone who can own the entire Meta advertising process:

Research → Angle → Creative → Launch → Test → Analyze → Optimize → Scale

You'll work across PCM portfolio companies to identify new customer acquisition opportunities, develop advertising concepts, launch campaigns, analyze performance, and continuously improve results.

Because you'll have exposure to multiple businesses, markets, offers, and customer types, there will be significant opportunity to take successful strategies from one campaign or portfolio company and apply those learnings elsewhere.

What You'll Do

• Develop new advertising angles, hooks, offers, and messaging concepts for our portfolio companies

• Manage campaigns across multiple geographic markets and portfolio companies
• Analyze performance and identify opportunities to improve CPL, CPA, lead quality, conversion rates, and customer acquisition costs
• Scale winning campaigns while maintaining acceptable acquisition economics
• Identify creative fatigue and maintain a consistent pipeline of new concepts and tests
• Analyze performance by creative, angle, campaign, geography, audience, placement, and offer
• Work with our internal teams to understand what happens after the lead is generated, including contact rates, appointment rates, sales rates, and lead quality
• Provide clear analysis of what's working, what's not working, why, and what we should test next

What We're Looking For

We're looking for a true direct-response performance marketer, not someone whose experience is limited to setting up campaigns in Ads Manager.

The ideal candidate:

• Has significant hands-on experience with Meta Ads
• Has successfully managed lead generation and direct-response campaigns
• Understands that creative and advertising angles are often the biggest drivers of performance
• Can independently generate and test new campaign ideas
• Is highly analytical and comfortable digging into performance data
• Understands Meta campaign structure, bidding, attribution, tracking, and optimization
• Knows how to diagnose an underperforming campaign
• Can manage multiple businesses, campaigns, markets, and priorities simultaneously
• Moves quickly and has a strong testing mentality

Home Services Experience Strongly Preferred
