Why Yomly?

At Yomly, we’re redefining HR automation by empowering leaders, people teams, and employees to work smarter and more effectively. Our platform delivers HR and payroll solutions that provide deeper insights and enhance operational efficiency.

Our Platform Engineering team ensures that product squads can deploy confidently, innovate quickly, and maintain high standards of reliability and security. As we grow, platform reliability and operational excellence are mission-critical. You’ll join at a formative moment — helping shape the systems, tools, and culture that make reliability real at scale.

What will you do?

As a Staff Platform Engineer, you will operate as a senior individual contributor whose work consistently spans multiple squads and company-wide systems. You’ll set technical direction, define patterns, and deliver high-leverage improvements - balancing hands-on engineering with thought leadership, mentoring, and cross-team influence to raise the bar for reliability, developer productivity, and operational excellence.

Core Responsibilities

Engineering & Technical Leadership

• Design and deliver scalable, observable, and resilient infrastructure for our AWS-native stack (EKS, Aurora, Terraform).
• Define and socialise reliability design patterns (resilience strategies, failover models, rollback/alerting standards).
• Lead improvements in CI/CD, release automation, incident response, and developer experience.
• Actively contribute code and reviews — especially for early-stage, complex, or cross-cutting work.
• Make deliberate trade-offs that balance speed, resilience, and cost efficiency.
• Guide best practices for GitHub-based workflows (branching, actions, bots, reviews) to improve developer productivity and release confidence.

Observability & Operational Readiness

• Advance monitoring maturity: richer dashboards, alerts, and instrumentation.
• Define and embed SLOs and error budgets across teams.
• Lead post-incident reviews, using them to coach others and strengthen operational muscles.
• Proactively drive systemic reliability improvements across services.
• Instrument and monitor GraphQL and API gateway performance, ensuring resilient, observable, and cost-efficient query handling.

AI-Native Platform Leadership

• Embed AI and automation into reliability and observability workflows (e.g. AI-driven alerting, anomaly detection, automated incident triage).
• Pilot and scale new AI-native practices, ensuring they improve productivity, resilience, and cost efficiency.
• Shape Yomly’s organisational approach to AI/agent adoption in platform engineering, influencing standards and accelerating safe, ambitious adoption across teams.

Influence & Mentorship

• Elevate engineering practices through peer mentorship, design reviews, and knowledge sharing.
• Be a visible advocate for reliability, resilience, and platform-first thinking.
• Shape ways of working across squads — championing best practices in infrastructure, testing, observability, and CI/CD.
• Act as a “force multiplier” by raising the bar for technical excellence across multiple teams, mentoring peers (including senior engineers) to navigate complex trade-offs and grow their leadership impact.

Strategy & Organisational Impact

• Partner with engineering leadership to translate company strategy into grounded technical initiatives.
• Engage directly with vendors (AWS, New Relic, PagerDuty) — proactively managing costs, capabilities, and risk.
• Ensure audit-readiness for SOC 2 / ISO 27001, embedding compliance into platform design.
• Shape and influence platform strategy in partnership with engineering leadership, ensuring technical direction aligns with company goals, platform health, and cost discipline.

Recruiting & Culture

• Actively contribute to recruiting and interviewing, calibrating and upholding the hiring bar for Senior and Staff-level engineers, and influencing how Yomly attracts and assesses top talent.
• Represent Yomly externally (conferences, meetups, communities) as a technical ambassador.
• Coach and mentor peers across teams, strengthening Yomly’s technical leadership pipeline.

Success Metrics (first 12 months)

• Platform availability (rolling 90 days) - aligned with customer trust and uptime commitments
• Median time-to-production — accelerating business impact through faster delivery
• Median time-to-recovery (MTTR) — directly improving customer trust and retention
• Change failure rate — raising quality while maintaining delivery velocity
• AWS cost per active employee record — contributing to gross margin efficiency
• Security incident response SLO compliance — protecting customers and regulatory trust
• Audit readiness (SOC 2 / ISO 27001) — ensuring enterprise-grade compliance and commercial viability

What We’re Looking For

Must Have

• Significant experience in Platform Engineering, DevSecOps, or SRE within AWS-based architectures, ideally B2B SaaS serving 10k+ DAUs.
• Proven track record at Senior Engineer or above with influence across teams.
• Strong foundation in AWS infrastructure (EKS, Aurora/RDS, IAM).
• Expertise in Infrastructure-as-Code (Terraform strongly preferred).
• Hands-on experience improving CI/CD, monitoring, and release workflows.
• Deep understanding of SLOs, error budgets, and incident management.
• Comfort balancing pragmatic delivery with long-term technical soundness.

Nice to Have

• Familiarity with observability stacks (Prometheus, CloudWatch, Grafana, New Relic).
• Experience optimising AWS costs at scale.
• Exposure to SOC 2 / ISO 27001 audits and compliance frameworks.
• Passion for technical mentorship, recruiting, and shaping high-performance engineering culture.

Mindset & Culture Fit

We’re building a culture of ownership, urgency, and grit. You’ll thrive here if you:

• Run toward problems, not away from them.
• Push for meaningful impact even when the path isn’t fully clear.
• Balance speed and resilience with pragmatic decision-making.
• Raise the bar for yourself, your peers, and Yomly’s engineering culture.
