Engineering Manager-Database Reliability

How you'll help us achieve it

Wave is now the largest financial institution in Senegal and Côte d'Ivoire with millions of users growing rapidly year-on-year.

And we’re still in the early days of our product roadmap and potential impact on people’s everyday lives.

You’ll lead the database reliability team which ensures that Wave’s databases are as “always up” as possible and can scale as our user base grows.

Database reliability is critical to Wave for two reasons:

1. We’re one of the fastest-growing financial services ever which causes a steady stream of new scalability challenges.
2. We’ve become critical infrastructure for many of our users—if we go down they can’t access their money. 

Because of this keeping a reliable and secure infrastructure are two of our top engineering priorities.

As an engineering manager you will:

• Support the engineers in architecting maintaining and evolving reliable high-performance database technologies across multiple environments.
• Mentor and coach a diverse globally distributed team of DB engineers.
• Shape and refine processes like incident response postmortems and capacity planning to ensure smooth ops.
• Collaborate with infrastructure product and security teams on platform database initiatives.
• Drive best practices for monitoring cost optimisation and performance tuning in Postgres CockroachDB and any future database we adopt.
• Hire and grow the team as needed shaping Wave’s DB reliability culture and standards.

Our stack (prior experience is a strong plus but not required):

• backend: Python 3 (+ mypy)
• API layer: GraphQL
• android frontend: Kotlin/Jetpack
• iOS frontend: Swift/SwiftUI
• web frontend: TypeScript/React
• database: Postgres/CockroachDB
• infrastructure: GCP/Terraform
• orchestration: Kubernetes

Key Details

• This is a fully remote role.

  Candidates must be based in one of our talent hub countries or in one of our operating markets in Africa including Senegal Côte d'Ivoire or Burkina Faso.

• Wave provides a yearly $1 200 stipend to support coworking meetups with teammates.
• Remote team members are expected to travel to our operational markets (e.g.

  Senegal or Côte d'Ivoire) at least once a year.

  Exceptions apply but we’ve found this key to understanding our users and product.

• Our salaries are competitive and are calculated using a transparent formula.

  For this role depending on your level and location we offer a salary of up to $227 900 USD plus a generous equity package.

• Major benefits:
  • Subsidized health insurance for you and your dependents and retirement contributions (both vary from country to country).
  • 6 months of fully paid parental leave and subsidized fertility assistance.
  • Flexible vacation with most folks taking between 21-30 days exclusive of statutory holidays.
  • $10 000 annual charitable donation matching.

Requirements

• You have at least five years of experience as a manager supporting database or storage teams.
• You’re willing to travel to Africa once per year for ~6 days (Wave covers all costs).
• You will have demonstrable people management experience: coaching performance evaluation mentorship and career development.
• You have relevant project management experience: specifically prioritisation tracking schedules and deadlines communicating across team/org boundaries.
• You have experience managing process design: running a smooth on call rotation incident response postmortems load testing capacity planning etc.
• You have hiring experience: predicting staffing needs designing interview loops evaluating candidates assisting with closing candidates at offer stage.

Technical Skills

• Proven track record of running mission-critical databases in production (replication backups migrations HA/DR).
• Skilled with Kubernetes and container orchestration (experience running DB workloads in K8s is a bonus).
• You have experience working in Cloud (preferably GCP) or Data Center infrastructure.

You might be a good fit if you

• Care a lot about working on software whose mission you believe in.

  Working at Wave positively impacts millions of lives through fast and cheap mobile money services.

  By helping us stay reliable and scalable you’ll have a big impact on the lives of lots of underserved people.

• Want to be part of an engineering culture that values simple and straightforward architecture over cutting-edge shiny tech.

  This helps us keep Wave simple to operate and makes it easier to achieve our reliability goals.

• Want to work on a team where it’s easy to collaborate.

  Our mission-focused culture makes sure that everyone you’ll work with is here primarily for the same reason—to make our users’ lives better.

  That alignment makes it easy to work with anyone across the company even if there’s some tension between your short-term goals.

  This is especially helpful for teams like infrastructure that collaborate closely with many other product teams.

• Enjoy solving complex performance and reliability challenges in large-scale database systems.

About the Database Reliability Team

The Database Reliability teams’ scope includes:

• Building tooling to observe and debug outages and performance problems
• Hardening Wave’s backend to be more resilient to incidents
• Enabling product teams to discover and fix reliability/performance issues in code they own
• Responding to incidents analyzing postmortems and prioritizing the resulting action items

Some recent projects as examples of specific things the team has worked on:

• Scale our databases to handle 10x load
• Automate backup disaster recovery and several maintenance operations
• Migrate to CockroachDB

About engineering at Wave

We care about the big picture. We don’t hire engineers to just ship tickets.

We hire them to solve problems.

That means caring deeply about outcomes understanding context and jumping in wherever something’s broken even if it’s technically “not your area.” When we see problems inefficiencies or opportunities to make something better we act.

We dig into operational issues clarify fuzzy product specs or step into unfamiliar code to help unblock teammates.

We move as fast as possible. Speed matters.

It lets us try things quickly get feedback early and course-correct while it’s cheap.

So we write small PRs.

We aim for MVPs.

We leave TODOs and file follow-ups.

We don’t over-perfect v1.

That said we’re building a financial product.

Some things—like money movement correctness or security—deserve more caution.

We like boring technology. We favor tools that are reliable well-understood and easy to debug.

This keeps us focused on solving meaningful problems instead of wrestling with unpredictable infrastructure.

If a new technology helps us move faster build safer or solve a real need we’ll consider it.

But we don’t adopt tools just because they’re new—we adopt them because they’re right.

Simplicity is a strategy.

It lets us focus our energy where it matters most: serving our users.
