- **Location:** New York, NY
- **Employment:** contract
- **Work type:** remote
- **Posted:** 2026-10-08

## Job description

The Opportunity We’re partnering with a leading global management consulting firm that advises C-suite leaders on their most complex problems. The firm is building an internal platform to make AI-assisted software development consistent, secure, and repeatable across its product portfolio, covering everything from how code gets written and checked to how it ships and runs in production.

This role owns the foundation underneath all of it. You’ll set the technical direction for infrastructure, delivery, security, and developer experience, and you’ll build much of it yourself. The goal is a platform that every product team inherits by default and that keeps getting better after you’ve moved on to the next problem.

Expect a mix of hands-on engineering, architecture leadership, and mentoring. This role is remote within the U.S.

## What You’ll Own

- Set the platform’s architecture: one container-orchestrated runtime, strong isolation between client engagements, and reusable, versioned infrastructure as code that spins environments up and down on demand
- Build identity, networking, and observability in from the start, with no long-lived credentials, just-in-time audited access, SLOs and alerting, and per-engagement cost tracking (AI spend included)
- Own shared CI/CD and the gate framework behind it, so quality, security, and AI-governance checks can block releases, and compliance evidence (scanning, signed artifacts, SBOMs, SOC2/ISO 27001) comes out of every build automatically
- Package the AI-assisted dev environment as a real product with hard sandbox boundaries for coding agents, and measure the platform by developer outcomes like setup time, pipeline speed, and adoption
- Lead major architecture decisions through written trade-off docs, advise senior stakeholders on platform risk, and mentor engineers and vendor partners

## What You Bring

- 15+ years (Principal) or 10+ years (Staff) in software, platform, or infrastructure engineering. Platform work for consulting or professional services firms, including client isolation and data residency, preferred
- Fleet-scale infrastructure as code with Terraform or OpenTofu, plus Terragrunt or similar: module design, remote state, multi-environment layouts
- Production experience running multi-tenant Kubernetes, including GitOps, network and admission policies, workload identity, and tenant isolation. vcluster or Crossplane preferred
- CI/CD built as a shared platform (GitHub Actions or similar), with reusable workflows, org-wide branch protection, and enforced gates. Developer portal experience (Backstage, Port) preferred
- Hands-on cloud identity and network security on Azure, AWS, or GCP: workload identity federation, RBAC, private networking, WAF, DNS. Certifications such as Azure Solutions Architect, CKA/CKS, or CISSP preferred
- Security and compliance automation: scanners like Snyk, Checkov, or Trivy; policy engines like OPA, Kyverno, or Azure Policy; supply chain controls (signing, provenance, SBOM); SOC2 and ISO 27001 evidence. Experience sandboxing AI coding tools (Claude Code, Copilot, etc.) preferred
- Production observability with OpenTelemetry or similar: collector design, SLOs and error budgets, alert routing, incident response, chaos testing. FinOps experience (cost allocation, showback, optimization) preferred
- Real application development experience in Go, Python, or TypeScript, plus solid habits around testing, code review, trunk-based development, and releases
- Strong written and verbal communication, including with executives. A track record of teaching through internal docs, workshops, or engineering communities preferred
- Comfort working in Agile, cross-functional product teams

- **Founders**: Matt Johnson (CEO/Owner)

## Core Business

- Mission or purpose statement: "We complete work with purpose and precision. We lead with humility, drive, and wisdom. We take care of what is entrusted to us, including time, budget, relationships, and trust."

## Products & Services
- **Embedded Teams**: Top-tier talent that integrates seamlessly with a client's team, providing specialized expertise that scales with the vision while maintaining flexibility as priorities shift.
- **Scoped Projects**: Time-defined project teams with clear objectives and predictable costs, covering Discovery, MVPs, technical validation, brand development, and more.
- **Recruiting Services**: Full-cycle talent acquisition for direct placement, contract-to-hire, or embedded recruiters, finding hidden talent aligned with technical needs and company culture.

- **Growth Signals**: 38.3% LinkedIn follower growth (yearly); expanding headcount with 12 new hires in the last year; multiple office locations across the US and Brazil

## Competitive Advantages
- **Three-in-one model**: Unlike traditional staffing agencies focused solely on headcount, Midwestern offers embedded teams, scoped projects, and recruiting under one US contract, providing flexibility that rigid staffing models cannot match.

## Strategic Focus
- Current priorities include scaling the embedded teams model for AI-era work, expanding into new markets (notably Brazil), and deepening partnerships with growth-stage tech companies.
- Emphasis on "flexible talent, global reach" — enabling clients to scale up or down easily without overcommitting.

- **Notable perks**: Opportunity to work on impactful products that have raised over $450M; exposure to a wide range of clients from startups to Fortune 500; clear career progression paths.
- **Engineering culture**: 39% of staff are in technical roles (47 people), with strong seniority distribution (26% specialist, 16% other management, 12% manager, 9% senior). Team members come from diverse backgrounds including DevMountain, Jack Henry, Leggett & Platt, and Gloo.
- **Growth opportunities**: 11% yearly headcount growth indicates a scaling organization with upward mobility for high performers.
