We’re looking for a Software Engineer to join the PM Benchmarking team in Mexico City. This team designs and executes competitive performance testing that benchmarks MongoDB against alternative technologies, while also building the reusable tooling, frameworks, and engineering practices needed to scale that work over time.
This role is a strong fit for an engineer who wants meaningful hands-on coding time, enjoys performance analysis, and is motivated by turning ambiguous technical questions into clear plans, repeatable systems, and high-impact outputs. You will work across the full lifecycle of a benchmark initiative: design, code, run, analyze, and communicate findings. You will also help improve the internal tooling and engineering workflows that make this work faster, more reliable, and more useful across MongoDB.
What you’ll do
Design performance and benchmarking workloads that reflect realistic customer or product scenarios
Build and improve production-quality internal tooling, test harnesses, automation, and reusable workload components
Write and maintain code primarily in Python, while adapting to adjacent tools and technologies as needed
Run benchmarks across cloud environments and database platforms, with attention to fairness, noise reduction, cost, and repeatability
Analyze latency, throughput, scalability, and infrastructure signals to identify bottlenecks and explain results clearly
Translate broad business or engineering questions into scoped technical plans, success criteria, and execution milestones
Partner closely with Engineering, Product, Sales, and other stakeholders to ensure testing work is relevant and actionable
Produce clear technical documents, reports, and summaries that connect findings to product decisions and field value
Help shape team standards for documentation, onboarding, prioritization, and benchmark execution as the team continues to mature
Mentor peers where appropriate and contribute to a collaborative, low-ego engineering culture
What we’re looking for
5+ years of experience building, debugging, and improving distributed and/or highly concurrent software systems
Strong software engineering fundamentals, including writing maintainable code, profiling performance, and debugging complex issues
Hands-on experience with performance testing methodologies such as load, stress, latency, or scalability testing
Experience designing and implementing benchmarking or performance-validation workflows
Strong coding skills in Python or a similar language, plus the ability to learn new stacks quickly
Strong hands-on experience with at least one of the three major cloud providers used for this role, AWS, Azure or GCP, including the practical trade-offs involved in running reliable applications at scale
Strong hands-on experience with PostgreSQL, MySQL, Aurora, Cassandra, or other competing data platforms
Ability to reason about relational and document data models, distributed systems behavior, and infrastructure bottlenecks
Strong written and verbal communication skills, especially when explaining technical findings to different audiences
Ability to work with ambiguity, define structure where needed, and operate with a high degree of ownership and autonomy
Bachelor’s degree in Computer Science or a related field, or equivalent practical experience
Nice to have
Experience with MongoDB architecture, MQL, and MongoDB performance tuning
Experience with CI/CD systems and integrating automated tests into engineering workflows
Experience creating reusable technical documentation, runbooks, or internal playbooks
Success in this role
In your first 30 days
Build a clear understanding of the team’s current workloads, tooling, roadmap, and stakeholder landscape
Complete onboarding and identify the main technical systems, docs, and knowledge gaps relevant to your work
Start contributing code, review feedback, and execution support on active benchmark efforts
In your first 90 days
Independently contribute to the design, coding, execution, and analysis of multiple benchmark initiatives
Improve at least one area of the team’s tooling, documentation, or
