Alejandro Rivera
Summary
Experience
- Architected the core inference scaling layer for API services, managing 12M+ daily active users across global regions while maintaining 99.99% availability.
- Reduced infrastructure overhead by $850K annually by implementing a custom resource scheduler for GPU-intensive workloads that optimized cluster utilization.
- Spearheaded a cross-functional initiative with 9 engineers to standardize service mesh architecture, decreasing inter-service latency by 42%.
- Directed the migration of legacy monolith components to a containerized microservices architecture on Kubernetes, improving deployment frequency from weekly to daily.
- Designed a real-time telemetry processing engine capable of handling 4.5M events per second using Kafka and Go, replacing a legacy Ruby pipeline.
- Optimized database query patterns for the analytics dashboard, resulting in a 58% reduction in P99 latency for customer-facing reports.
- Mentored 5 mid-level engineers on distributed systems design, facilitating their transition into technical lead roles within the observability organization.
- Owned the lifecycle of the internal observability platform, ensuring consistent performance for critical alerting services across 140+ internal microservices.
- Developed the automated tax filing engine, processing payroll for 60,000+ small businesses with 100% compliance accuracy across 50 states.
- Refined the onboarding workflow for new employers, increasing the conversion rate from registration to first payroll run by 34%.
- Established the first internal Ruby on Rails style guide and automated linting pipeline, adopted by 4 product teams to improve cross-team code consistency.

How to write better bullet points
Managed the API scaling layer for OpenAI users.
Architected the core inference scaling layer for API services, managing 12M+ daily active users while maintaining 99.99% availability.
It moves from a vague management task to a specific architectural achievement with clear scale and reliability metrics.
Optimized GPU usage to save the company money.
Reduced infrastructure overhead by $850K annually by implementing a custom resource scheduler for GPU-intensive workloads.
It provides a concrete financial outcome and names the specific technical mechanism used to achieve the savings.
Helped teams use a service mesh to reduce latency.
Spearheaded a cross-functional initiative with 9 engineers to standardize service mesh architecture, decreasing inter-service latency by 42%.
It highlights leadership across teams and quantifies the resulting performance gain.
Staff Software Engineer resume writing tips
- Highlight technical initiatives that solved problems for multiple teams, not just your immediate squad.
- Quantify infrastructure cost savings or latency improvements to prove high-level architectural impact.
- Detail instances where you standardized engineering practices or mentored others into leadership roles.
Common mistakes
- Focusing too much on individual coding tasks instead of architectural strategy. Staff roles require evidence of force-multiplier impact across the organization.
- Omitting the business context of technical decisions. You must explain why a technical migration or optimization mattered for the company's bottom line.
- Failing to show leadership without formal management authority. You need to demonstrate how you influenced roadmaps and technical standards through expertise.
Frequently asked questions
Is this resume right for someone with 10+ years of experience? Yes if your experience focuses on setting technical direction for multiple business units rather than just executing feature roadmaps.
Yes if your experience focuses on setting technical direction for multiple business units rather than just executing feature roadmaps.
Yes, if your recent roles involve setting technical direction for multiple teams rather than just executing features. It is less suitable if you are looking for your first senior role and haven't yet led cross-functional architectural changes.
What if my experience is in fintech rather than AI or observability? Yes, because staff-level principles like solving complex scaling or compliance challenges translate across all industries, including fintech.
Yes, because staff-level principles like solving complex scaling or compliance challenges translate across all industries, including fintech.
The principles of staff-level impact remain the same regardless of industry. Focus on how you solved domain-specific scaling or compliance challenges, much like how this resume highlights the tax filing engine at Gusto.
What if I don't have exact dollar amounts for my impact? Use proxies like percentage improvements in system uptime, developer velocity, or resource utilization to quantify your architectural impact.
Use proxies like percentage improvements in system uptime, developer velocity, or resource utilization to quantify your architectural impact.
You can use other proxies for impact such as percentage improvements in system uptime, developer velocity, or resource utilization. In this resume, Alejandro Rivera quantifies inter-service latency and user growth, which are powerful signals to recruiters.
How much of this layout should I keep? Prioritize your most recent, high-impact roles and adapt the skills section to reflect the specific architectural domains required by the employer.
Prioritize your most recent, high-impact roles and adapt the skills section to reflect the specific architectural domains required by the employer.
Keep the emphasis on your most recent, high-impact roles and ensure your skills section reflects the specific architectural domains required by the job description. You should adapt the bullet points to reflect your unique technical wins while maintaining the focus on organizational-level influence.
What do hiring managers focus on most at the staff level? Managers look for evidence that you can independently solve ambiguous problems spanning multiple systems with long-term positive business effects.
Managers look for evidence that you can independently solve ambiguous problems spanning multiple systems with long-term positive business effects.
They look for evidence that you can operate independently and solve ambiguous problems that span multiple systems. They want to see that your technical decisions have a long-term positive effect on both the codebase and the engineering team's efficiency.
