Senior Software Engineer

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.

• 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

• 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

• 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

• 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

• 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 execution workflow
• Build strong working relationships with key cross-functional partners

• Own meaningful benchmark or tooling work from scoping through delivery
• Improve repeatability, clarity, or efficiency in how the team designs, runs, or reports on tests
• Contribute to mentorship, documentation, or process improvements that increase team autonomy

• Be a trusted technical contributor across benchmark design, tooling, and analysis
• Influence how the team prioritizes and scales its work
• Expand your scope through technical leadership, cr
