FullStack Developer with AML and Financial Services …, Johannesburg, South Africa

Description

We're looking for a hands-on Software Engineer who loves building high-quality software using modern engineering practices. You will design, build, test and continuously deliver cloud-native risk services on Microsoft Azure using our C#/.NET. You lead through craft, example, mentorship and by raising the engineering bar.

What You Will Do Core Engineering

• Design APIs and message contracts (REST/gRPC/event) with clear versioning and backward compatibility.
• Write clean, maintainable, refactor-friendly code in C#/.NET.
• Work with existing and new SQL code
• Contribute to the modernisation of existing services by building new .NET-based solutions and integration layers, improving modularity, testability, performance and observability while avoiding risky rewrites.
• Build and evolve Azure-hosted containerised services — e.g. Docker-based workloads running on Azure Kubernetes Service (AKS) and/or Azure Container Apps, plus event-driven components, storage and data pipelines.
• Work with Angular/React code to support or extend new and existing UI components when needed.
• Design, build, and maintain ETL/ELT pipelines for ingesting data from internal and external sources.

• Develop scalable data processing solutions using Azure Data Factory, Databricks/Spark, SQL Server, Synapse, or equivalent.
• Build and optimise data lakes, warehouses
• Implement data quality checks, monitoring, and lineage tracking.
• Optimise SQL queries, stored procedures, and analytical data models.
• Integrate structured and unstructured data from multiple systems, APIs, and database

Quality & Delivery Practices

• Practice test-first / TDD for business logic; use property-based and contract tests where valuable.
• Help the team adopt Continuous Integration (single trunk/main, small frequent commits, fast green builds).
• Automate deployments (Continuous Delivery) with Azure DevOps pipelines and Infrastructure as Code (Bicep/Terraform).

• Strengthen the testing pyramid: fast unit tests, service/component tests, selective integration/system tests.
• Embed observability (structured logging, metrics, tracing) from the start.
• Use short-lived feature branches (hours/days) merged via peer-reviewed pull requests; keep main releasable.
• Ensure regulated-app test gates: security scanning (SAST/DAST), dependency vulnerability checks, data masking tests, audit logging verification.

• Treat non-functional tests (performance, resilience) as part of definition of done where risk impact warrants.
• Minimise manual handoffs; optimise flow from idea to production.

AI Augmentation & Enablement

• Use AI tools (e.g. GitHub Copilot) to accelerate coding, test generation, documentation drafts — with critical review.
• Curate effective prompts and patterns; avoid leaking secrets or sensitive data.
• Teach teammates how to use AI responsibly to improve speed and quality.
• Identify where AI adds leverage (e.g. scaffolding .NET code, generating edge-case tests) vs where human design thinking is essential.

Collaboration & Mentorship

• Pair/mob program when it improves design or spreads knowledge.
• Give pragmatic code reviews: clarity, simplicity, testability, correctness, maintainability.
• Share learning through lightweight design spikes, brown bags, and example repos.
• Raise the bar without gatekeeping; coach rather than dictate.
• Facilitate respectful peer review sessions (synchronous or async) focused on learning and improving code, not defending ego. 
• Encourage inclusive language and psychological safety in reviews; critique code, not people.

Continuous Improvement

• Help reduce sources of toil (long builds, flaky tests, manual deployments).
• Champion trunk-based development and improving deployment frequency safely.
• Use metrics (lead time, change fail rate, MTTR, test feedback time) to guide improvements — not to assign blame.

Must Have

• 6+ years professional software engineering, building production systems.
• Strong in C#/.NET
• Solid SQL skills (intermediate or above) and experience working with an ORM (e.g. Entity Framework Core or similar). 
• Experience working with legacy systems and incremental modernisation.

• Experience with document databases such as CosmosDB
• Proven application of TDD / automated testing (can explain strategy trade-offs and test design).
• Hands-on CI/CD experience (Azure DevOps or similar) with Infrastructure as Code (Bicep or Terraform).
• Practical experience using AI coding tools (e.g. Copilot) and integrating them into daily flow.
• Strong Azure fundamentals, especially:
  • Containerisation (Docker) and Azure Kubernetes Service (AKS) and/or Azure Container Apps
  • Messaging, storage, identity, pipelines 
  •  

 Certifications:

AZ-900 (Microsoft Azure Fundamentals) – Mandatory

AZ-204 (Developing Solutions for Microsoft Azure) – Certified or in-progress

• Clear, concise technical communication (written and verbal).
• Experience delivering in regulated or high-governance environments (e.g. financial risk, Basel/BCBS, audit constraints) with demonstrated test and evidence practices.
• Ability to identify and execute safe modernisation strategies (strangler patterns, incremental refactors) rather than large rewrites.

How We Work

• Trunk-based development, code always releasable.
• Test-first mindset; production-like environments early.
• “Automate it” bias for repeatable manual steps.
• Keep designs simple; evolve as we learn — prefer readable over clever.
• Psychological safety: problems are surfaced early; blame-free postmortems.

Mindset & Behaviours

• Curiosity: asks why before how.
• Ownership: finishes what is started; leaves code better than found.
• Pragmatism: balances ideal engineering with delivery goals.
• Teaching orientation: lifts others consistently.

Integrity: challenges poor practices respectfully.
