Summary Generated by Built In

Jahnel Group’s mission is to provide the absolute best environment for software creators to pursue their passion by connecting them with great clients doing meaningful work. This is a full time position with one of our closest clients.

Who we are looking for

We’re looking for a hands-on Principal Software Engineer who thrives in complex, fast-moving environments and wants to own the technical direction of mission-critical systems.

This is a deeply technical, high-ownership individual contributor role. You’ll be the most senior engineer on the platform, responsible for setting architecture, guiding technical decisions, and ensuring both systems stay stable, scalable, and shipping fast.

You should be comfortable operating across backend systems, frontend interfaces, infrastructure, and emerging AI workflows, and you should naturally think in terms of systems, tradeoffs, and long-term maintainability.

The ideal candidate is someone who:

  • Owns systems end-to-end in production
  • Makes strong architectural decisions and documents them clearly
  • Moves fluidly across languages and stacks
  • Raises the engineering bar through code, not just direction

You’ll work across both a mature forecasting platform and a newer AI-native onboarding system, helping shape how modern retail planning software evolves.

Responsibilities
  • Own technical architecture and system design across two core platforms.
  • Keep production stable and the release cadence fast as the platform grows.
  • Make and document the big calls — what to consolidate, what to harden, what to leave alone.
  • Stand up the things a maturing platform needs: observability, runbooks, and engineering guardrails.
  • Level up the team through code review, pairing, and clear written decisions.
Some Must-Haves
  • 10+ years of professional software engineering experience
  • Deep experience building and operating production systems on AWS
  • Strong expertise in TypeScript / Node.js, with Next.js + React
  • Advanced PostgreSQL experience (schema design, scaling, performance tuning, multi-tenant systems)
  • Strong background in event-driven / distributed systems (queues, async workflows, background processing)
  • Hands-on experience with infrastructure-as-code (Terraform, CDK, or OpenTofu)
  • Proven ownership of systems from architecture through production support / on-call
  • Comfortable actively using AI coding tools (Cursor, Claude Code, etc.) as part of daily development workflow
Technical Requirements
  • AWS: Lambda, Step Functions, ECS Fargate, SQS/EventBridge, RDS, S3, IAM
  • Strong backend engineering in TypeScript/Node.js (primary)
  • Experience working across multiple languages (Go and/or Python preferred)
  • Next.js / React frontend development experience
  • Production-grade system design (scalability, reliability, observability)
  • Experience debugging and optimizing distributed systems
Nice-to-Haves
  • Experience with Go and/or Python in production environments
  • Exposure to LLM / agentic systems (Bedrock, OpenAI, Anthropic, prompt workflows, evals)
  • Background in retail, inventory, supply chain, or forecasting systems
  • Experience building data-heavy or operational planning tools
  • Prior work in high-scale infrastructure environments (AWS-heavy orgs, large tech companies)
Where We’re Looking For It
  • Remote (U.S.-based preferred)
  • NYC is a plus, but not required
  • Ability to travel onsite approximately once per month
Compensation Package (Salary Transparency for US-Based Employees)
  • Salary Range: $175,000+
      • Salary is negotiable and the range can be increased based on qualifications, certifications and experience  

Skills Required

  • 10+ years of professional software engineering experience
  • Deep experience building and operating production systems on AWS
  • Strong expertise in TypeScript / Node.js, with Next.js + React
  • Advanced PostgreSQL experience (schema design, scaling, performance tuning, multi-tenant systems)
  • Strong background in event-driven / distributed systems
  • Hands-on experience with infrastructure-as-code (Terraform, CDK, or OpenTofu)
  • Proven ownership of systems from architecture through production support / on-call
