Level: Intermediate (3–5 years experience)

Reporting to: Lead Engineer / Technical Director

Role Overview

We are looking for an Intermediate Software Engineer who enjoys solving real engineering problems — not just delivering tickets.

You will design and build backend services powering high-availability financial systems
, working closely with experienced engineers and cross-functional stakeholders. You’ll have autonomy in how you approach problems, while still having support whenever you need it.

This role is perfect for someone who:

  • Wants to grow quickly in a high-trust, delivery-focused environment
  • Can take an idea from discussion → implementation → deployment
  • Learns fast and adapts well when priorities shift

No prior banking experience is required —
we will enable you on the domain
.

What matters is your Python engineering strength and your ability to think
.

What You’ll Do Backend Development
  • Build and maintain API-driven services using Python (FastAPI / Django / Flask)
  • Contribute to modular microservices that support analytics and operational systems
  • Apply asynchronous programming where performance matters
Systems Design & Problem Solving
  • Participate in design discussions, propose solutions, improve reliability and performance
  • Help break down complex requirements into manageable technical work
Cloud & Dev Ops Exposure
  • Deploy containerised applications using Docker and CI/CD pipelines
  • Contribute to monitoring, logging and stability improvements
Data and Integration
  • Work with relational databases (e.g., Postgre

    SQL) and caching layers (e.g., Redis)
  • Integrate services with messaging systems (e.g., Kafka / Rabbit

    MQ)
Quality & Support
  • Write maintainable, tested code
  • Assist in troubleshooting production issues as needed
What Success Looks Like Technical Ability

Write clean, reliable Python services; improve performance with guidance

Learning Agility

Pick up new concepts fast (tech + financial domain)

Delivery Ownership

Follow through on commitments; communicate early if blocked

Collaboration

Work openly with engineers, analysts and business users

Professionalism

Show maturity, punctuality, and care when working with clients

Minimum Requirements
  • Degree or NQF Level 7 equivalent in Computer Science, Engineering, Mathematics or similar
  • 3–5 years professional software engineering experience
  • Strong proficiency in Python 3.x
  • Hands-on experience building backend APIs/services (FastAPI, Django or Flask)
  • Experience with Docker and CI/CD pipelines (Git Hub Actions, Jenkins, etc.)
  • Good understanding of databases & writing efficient queries
  • Ability to work independently in a hybrid environment
  • Exposure to distributed / event-driven systems
  • Basic knowledge of async programming and messaging systems (advantageous)
  • Experience with Kubernetes or cloud platforms (advantageous)
Tech Stack You’ll Work With
  • Python 3.x (primary language)
  • FastAPI / Django / Flask
  • Docker
    • CI/CD (Git Hub Actions, Jenkins, Git Lab CI)
  • PostgreSQL
    • Redis
    • MongoDB
  • Kafka / Rabbit

    MQ (depending on projects)
  • Prometheus
    • Grafana
    • Sentry (observability)

You don’t need experience in all of these —
curiosity and willingness to learn are key
.

Growth & Culture

You’ll enjoy this role if you like:

  • Applying engineering thinking to real-world business problems
  • Designing the solution, not just following instructions
  • Learning new concepts fast and stepping into challenges
  • Building structure where none exists

You’ll have strong mentorship and a clear path to grow into Senior Software Engineer
.

Important Notes
  • This is a client-facing role in a regulated environment
  • Hybrid setup with flexible remote days
  • Supportive team, high pace — you’ll always be learning
  • You are required to undergo credit/criminal checks required by financial institutions

Apply if you want to solve real engineering challenges
, build credible experience in the Fin Tech domain, and grow fast in a team that values both people and delivery.
