Senior Engineer, Internal Tools

This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board.

About Us

We're building the world's leading cross-border fintech for emerging markets - empowering families, fueling local economies, and changing how millions access financial services.

Since our launch in 2019, we have transformed how money moves across borders with our operations spanning 6 out of 7 continents and covering both the busiest and most underserved (remittance) corridors. We tapped into a massive shift - from banks to phones - bringing digital finance to places where traditional systems never reached. The next stage of growth will fuel a network of services and products especially designed to make money more accessible to diaspora communities including local cards, and additional savings and payments features.

We're growing fast, backed by world-class investors, and scaling a product that blends real world impact with cutting edge fintech innovation.

Here's a little more:

  • Founded by Harvard grads and 3-time founders who previously built Segovia (acquired) and GiveDirectly (>$300M revenue, fastest-growing NGO in the world)
  • Backed by top investors including Spark Capital, Canaan, Reid Hoffman, Breyer Capital, Unbound, Wamda, and more
  • Built by global top performers from Bain, Google, McKinsey, Uber, Checkout, Bolt, and beyond - we move fast, stay humble, and care deeply about our mission
  • Truly global team - 250+ people, 50+ nationalities, 50+ languages
  • Guided by our values - ownership, impact, humility, and heart - in deed, not just word

The Role

We are looking for a Senior Software Engineer to join our growing engineering team to define, build and iterate on features for our internal tooling.

As an early member of the team, you will also have a lot of impact on our team culture, processes and norms.

Taptap Send is a cross-platform mobile app developed with React Native and TypeScript, which talks to a backend service written in Kotlin and backed by a PostgreSQL database, all of which runs on AWS and is managed via Terraform. Our internal tools leverage these technologies in addition to Web React and Python.

We're an encouraging environment that values both teamwork and autonomy, and have many exciting upcoming challenges, including: scaling up to handle increased volume and complexity, improving UI and UX to drive growth and retention, building internal tools, developing new small business solutions, and much more!

Your Responsibilities:

  • Take ownership of development of internal tool solutions
  • Build experiences across the stack using primarily Python, and on occasion Kotlin
  • Write well-tested, high quality code, with an eye towards generics and re-use
  • Work closely with design and product teams to regularly ship working features
  • Participate in release planning and deployment of released build
  • Mentor and advise team members
  • Evaluate and deliver timeline estimates for projects

Requirements:

  • 5+ years of professional experience building api applications using Python or Kotlin ideally.
  • Experience working in AWS cloud, and leveraging services like ECS, Lambda, RDS, DynamoDB, SQS, SNS, EventBridge.
  • Experience owning user-facing features end-to-end, from conception to launch
  • Experience developing software in a collaborative, multi-functional, and fast-paced environment
  • Experience working on systems that have real-world performance and reliability constraints
  • Strong communication and ability to manage conflicting priorities, setting expectations with stakeholders and be a driving force

Ideally:

  • Experience developing event driven system.
  • Experience CI, CD processes and tools.
