Python Engineer - Technical Architect/Lead

Job Title: Python Engineer - Technical Architect / Lead

Location: Atlanta, GA - Hybrid (3 Days per Week Onsite)

Employment Type: Full-Time (FTE)

About the Role

We are seeking an experienced Python Technical Architect / Lead to define the architecture

and technical direction. In this role, you will own end-to-end solution design for domain-aligned

services supporting customer onboarding, KYC, money movement, and IRA accounts. You will

lead a team of engineers, act as the primary technical point of contact, and ensure that solutions

are secure, scalable, compliant, and built to high engineering standards.

Key Responsibilities

 Define and own the end-to-end architecture for serverless, event-driven systems on

AWS, aligned with the AWS Well-Architected Framework.

 Apply Domain-Driven Design to establish service boundaries, and guide the use of

design patterns such as Saga, CQRS, outbox, circuit breaker, and idempotent

processing.

 Design RESTful and event-driven APIs using API Gateway, EventBridge, SQS, and Step

Functions, including API standards and versioning.

 Architect resilient vendor integrations and data models across PostgreSQL and

DynamoDB, with pipelines feeding Snowflake.

 Address non-functional requirements including scalability, performance, availability,

observability, and cost optimization.

 Embed security and compliance across the platform, including IAM, KMS, SSO/OAuth2

(Okta), PII protection, and audit logging.

 Produce architecture artifacts such as solution designs, Architecture Decision Records

(ADRs), and technical roadmaps.

 Lead and mentor the engineering team, define engineering standards (TDD, code

reviews, IaC, CI/CD), and contribute hands-on to critical components.

 Serve as the primary technical point of contact for clients, leading architecture

discussions and translating business requirements into technical solutions with clear

trade-offs.

 Partner with product and delivery teams on estimation, planning, and risk mitigation, and

support pre-sales activities as needed.

Required Skills and Experience

 Extensive experience in Python back-end development, with deep expertise in Django

or FastAPI.

 Proven experience architecting and delivering production systems on AWS serverless

services: Lambda, API Gateway, Step Functions, EventBridge, SQS, and DynamoDB.

 Strong command of Domain-Driven Design, event-driven architecture, microservices,

and distributed system design patterns.

 Expertise in PostgreSQL and data modelling, with SQLAlchemy or the Django ORM, and

solid understanding of NoSQL design for DynamoDB.

 Experience designing secure integrations using REST, OAuth2, and Okta, with emphasis

on reliability, retries, and idempotency.

 Strong grounding in test-driven development and testing strategy using pytest, moto,

and LocalStack.

 In-depth knowledge of AWS security (IAM, KMS, Secrets Manager) and secure handling

of PII.

 Demonstrated experience leading engineering teams and mentoring developers.

 Excellent communication and stakeholder management skills, with a track record of

working directly with clients.

 Hands-on experience using AI-assisted development tools such as Claude, Cursor, or

GitHub Copilot.

Good to have

 Experience in fintech, banking, wealth management, or other regulated industries.

 Infrastructure-as-code expertise with AWS CDK or Terraform, and experience designing

CI/CD pipelines.

 Experience designing ETL/ELT pipelines and working with Snowflake.

 Experience with observability tooling.
