What are the responsibilities and job description for the Backend Developer position at Javen Technologies, Inc?
Location: Farmington Hills / Metro Detroit, Michigan
Duration: 6 Months
Must Have
- AWS
- Building backend system
- deploying software
- Python and TypeScript
JOB DESCRIPTION
*Hybrid work. Candidates must be located in the Farmington Hills / Metro Detroit, Michigan area. No remote candidates.*
JOB DESCRIPTION
We are looking for a Lead Software Engineer to join our AI agentic engineering team. You will design and deliver guardrail components across services, define where and how enforcement should occur in systems, and mentor engineers on safe design and defensive programming patterns. You will also architect backend services, APIs, and integrations that apply software engineering discipline to govern how AI-driven systems behave across the engineering workflow.
This is a hands-on technical leadership role requiring strong proficiency in Python and TypeScript, a track record of delivering cross-service systems, and the ability to define enforcement patterns that other engineers follow.
What You''ll Do
Design and deliver backend services and APIs that enforce system behavior across multiple services
Define where and how enforcement, filtering, and validation should occur within system architectures
Build cross-service controls and establish the patterns other engineers implement against
Instrument and improve observability across service boundaries — structured logging, metrics, distributed tracing
Own shared tooling and platform components with broad organizational reach
Mentor engineers on safe design, defensive programming, and failure handling practices
Core Capabilities
Writes production-quality code with strong proficiency in Python and TypeScript
Demonstrates advanced experience working in cloud environments (AWS)
Designs and implements scalable backend services and APIs across service boundaries
Defines enforcement patterns and interface contracts consumed by other teams
Thinks in systems — reasons about cross-service dependencies, failure propagation, and contract stability
Communicates defensive design principles clearly to other engineers
Shows strong technical curiosity and forms clear, experience-backed opinions
What Differentiates This Role
This role is focused on how systems behave under misuse, failure, or unexpected inputs — not on building user-facing features. At this level, you are defining where enforcement lives and how it works across services, not just implementing within one. You bring both the technical depth to build these systems and the communication skills to make the patterns repeatable by others.
What You Will Bring
5–8 years of software engineering experience with strong proficiency in Python and TypeScript
Demonstrated experience delivering production systems on AWS (Lambda, Fargate, API Gateway)
Experience designing enforcement, filtering, or validation logic that spans multiple services
Track record of defining interfaces, contracts, or patterns adopted by other engineers
Ability to mentor junior and mid-level engineers on defensive design and safe coding practices
Clear written and verbal communication — able to define and document system-level enforcement patterns
Experience designing and building agentic workflows or multi-agent systems
Familiarity with LLM integration patterns — prompt injection detection, guardrail design, or output filtering
Nice to Have
Experience with AWS Bedrock — model invocation, guardrail configuration, or Agent Core runtimes
Experience with agentic or multi-step workflow systems or Background in platform engineering or developer tooling roles
