About the Role

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.
