What is a database, if not the heart of integrity and durability in a financial institution? People throughout history have been keeping records of their transactions. But in the late 13th century, Amatino Manucci was quietly working on an innovation that persists to this day: the double-entry accounting system. His books show sophistication and ingenuity that ultimately furthered the blossoming trade of medieval Europe. Double-entry bookkeeping represented a step forward in being able to account for all flows of value with precision, consistency, and durability.

That same fundamental desire for a consistent enduring record has pushed Mercury to build upon what we feel is a modern-day building block: PostgreSQL. It is the underpinning of our platform. PostgreSQL inspires us with its reliability, adaptability, and performance. We wield its features to solve our problems and deliver magical customer experiences. But we also see that we have room to improve and we want someone who can serve as our guide to better data systems.

You will join Mercury as its first DBRE. We have managed to draw on expertise and curiosity across the organization to get us to this point, but see value in having a full-time owner. You bring a sense of direction and organization that helps us unlock the next chapter of Mercury’s growth. PostgreSQL is wonderfully general, but you know its limits and can implement architectures that make sense for the features we are developing.

You will be part of the Stability team: a small group that holds SRE values and seeks to do high-leverage reliability and performance work that benefits Mercury engineering.

You will:

  • Guide product engineers towards structures and practices that maximize performance, efficiency, and reliability

  • Pair with product engineers on query performance improvements

  • Automate processes and distribute knowledge so that you are not a bottleneck

  • Drive database upgrades and migrations

  • Identify long-term architecture goals and plan, coordinate, and execute incremental steps to achieve those

  • Collect and present database metrics to inform scaling and architecture discussions

  • Educate product engineers who are generally excited about PostgreSQL, data consistency, correctness, immutability, and performance

  • Make code and infrastructure changes so that our applications better interact with the database

You should:

  • Have 5 years of experience administering PostgreSQL in medium-to-large organizations

  • Have experience with Amazon RDS, Google Cloud SQL, Azure Database, or similar managed offerings

  • Have 1 year of experience using Infrastructure-as-Code tooling: Terraform is preferred

  • Have deep query optimization experience with PostgreSQL

  • Know how to combine PostgreSQL with other data systems for cost efficiency, scalability, and reliability reasons

  • Be comfortable with a scripting language such as Python

  • Be open to learning Haskell/Persistent/Esqueleto to support product engineers

  • Be willing to learn and solve new problems

It would be nice if you:

  • Have experience with Amazon Aurora

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Mercury’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.


Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
