Senior Python Full Stack Technical Lead

SIT Polyglot Python Platform Evolving Toward Event-Driven Systems

About the Role

SIT Academy is seeking a hands-on Senior Python Full Stack Technical Lead to guide the engineering of its learner-facing and operational platforms. The Academy stack is Python-first—spanning Flask, FastAPI, and Django—integrated with a Hasura GraphQL data layer, a WordPress content surface, and Salesforce (Apex) as a system of record, all deployed to AWS on Kubernetes (Amazon EKS) with Terraform.

This is a builder-leader role: you will write and review production code, set technical direction, and mentor an onshore/offshore team. The architecture is deliberately evolving—today a mix of request/response services and point integrations, and on a clear path toward target-state event-driven systems. We need a lead who can keep the current platform healthy while steering the team toward asynchronous, decoupled, event-first patterns, and who treats that migration as an opportunity rather than a chore.

The Architecture & Where It’s Heading

A central part of this role is comfort with a polyglot, multi-surface platform and the discipline to evolve it coherently. The current landscape and target direction look like this:

• Python application tier built across Flask, FastAPI, and Django — a mix of lightweight services, async APIs, and fuller web/admin applications. Part of the lead’s job is bringing consistency (shared libraries, conventions, and service boundaries) across these frameworks.
• Hasura provides a declarative GraphQL (and REST fçade) data-serving layer over PostgreSQL-compatible tables, including event triggers that can emit changes for downstream consumers.
• WordPress serves content and marketing/learner-facing surfaces; the platform integrates with it rather than treating it as a silo.
• Salesforce (Apex) acts as a key system of record; integration patterns (CDC, platform events, REST/Bulk APIs, and Apex callouts) connect it to the Python tier.
• Target state: the platform is moving from synchronous, point-to-point integrations toward an event-driven architecture — durable events, asynchronous processing, and decoupled producers/consumers (e.g., via Hasura event triggers, Salesforce platform events / CDC, and a streaming/eventing backbone). Leading that transition is core to this role.
• Everything runs on Amazon EKS, provisioned with Terraform and shipped through CI/CD.

You don’t need to have used every one of these technologies in production, but you should be able to reason across them, judge when to introduce event-driven patterns versus keep things simple, and lead engineers through the migration without destabilizing what already works.

Core Responsibilities

• Provide hands-on technical leadership—architecture, design, code, and review—while mentoring onshore and offshore engineers and driving technical decisions.
• Design, build, and maintain Python services and applications using Flask, FastAPI, and Django, with attention to consistency, testability, and shared standards across frameworks.
• Define and drive the migration toward event-driven architecture—identifying integration seams, introducing events/async processing, and decoupling tightly-coupled flows incrementally.
• Build and consume APIs over the Hasura GraphQL/REST layer, including configuring and reacting to event triggers.
• Design and maintain integrations with Salesforce (Apex, platform events, CDC, REST/Bulk APIs) and with WordPress content surfaces.
• Implement Change Data Capture (CDC) and reliable messaging patterns for real-time, decoupled data synchronization.
• Write Infrastructure as Code with Terraform and containerize/deploy services on Amazon EKS.
• Create and maintain CI/CD pipelines for automated testing, quality gates, and deployment.
• Champion observability, security, performance, and data-governance practices across the platform.

Required Technical Skills

• 10+ years of software engineering experience with strong, current proficiency in Python 3.
• Production experience with at least two of Flask, FastAPI, and Django — and the ability to work fluently across all three.
• Strong grasp of asynchronous programming in Python (async/await, task queues such as Celery/RQ, background workers).
• Demonstrated experience designing and building event-driven and message-based systems (e.g., Kafka, Pulsar, SQS/SNS, or platform events) — or a clear track record of migrating synchronous systems toward them.
• Proven track record building internet-facing web applications deployed to a public cloud (AWS preferred).
• Solid RESTful and GraphQL API design and implementation.
• Experience integrating enterprise applications with Salesforce using REST APIs, Bulk APIs, Platform Events, Change Data Capture (CDC), and Apex-based integrations.
• Strong relational database skills with PostgreSQL (SQL modeling, performance, migrations).
• Hands-on experience with Docker, Kubernetes (EKS), and Terraform.
• Solid CI/CD and Git version-control / branching and PR-review skills.
• Experience integrating with third-party SaaS and systems of record via APIs and webhooks.
• Exposure to Salesforce Apex — able to read and work with Apex (triggers, classes, callouts) and reason about Salesforce data/automation when building and debugging integrations.

Preferred Qualifications

Experience with:

• Hasura (auto-generated GraphQL/REST, event triggers, permissions) or comparable declarative API layers.
• Deeper Salesforce development — hands-on Apex development, platform events, Change Data Capture, and the broader Salesforce integration ecosystem.
• WordPress integration, headless WordPress, or the WP REST API.
• Streaming/eventing platforms (Kafka, Pulsar, Kinesis) and CDC tooling (Debezium or equivalent).
• Observability and metrics tooling (Prometheus, Grafana, Dynatrace, OpenSearch).
• Test-driven development (TDD) and code-quality tooling such as SonarQube, with peer review via GitHub PR flows.

Knowledge Of

• Microservices and API security patterns; OAuth 2.0 and JWT authentication.
• Event sourcing, CQRS, and distributed-systems / decoupling design patterns.
• Data governance, privacy, and compliance requirements.
• EdTech domain and exposure to platforms such as Moodle, Open edX, or other Learning Management Systems (LMS) and Student Information Systems (Banner)
•  

Leadership & Communication

• Demonstrated ability to lead distributed onshore/offshore teams and mentor engineers.
• Clear, fluent written and verbal communication—able to explain trade-offs to engineers and non-technical stakeholders alike.
• Pragmatism in an evolving architecture: keeps today’s platform healthy while steering deliberately toward the event-driven target state.
