Job Description

Job Title: Senior Engineer, Internal Tools

Position Description: Protingent Staffing has an exciting direct hire Senior Engineer, Internal Tools with our client that is fully remote.

Job Description:
  • You are the engineering backbone of the internal tools team.
  • Building and maintaining the platforms that every team in the company relies on.
  • Your work directly increases organizational efficiency and enables teams to move faster.
  • You’ll own systems end-to-end, from scoping and architecture through production deployment and iteration, connecting multiple business systems into a seamless, reliable internal ecosystem.

Job Responsibilities:
  • Build & Ship:
    • Design, build, and maintain internal platforms and tools that serve People, Finance, Ops, Sales, and Engineering teams.
    • Own features end-to-end: requirements, architecture, implementation, testing, deployment, and monitoring.
    • Write clean, well-tested, production-grade code. You hold yourself to the same bar as customer-facing products.
  • Architecture & Integration:
    • Build API-first integrations across the internal ecosystem — connecting HRIS, CRM, finance platforms, knowledge management, and developer tools into a coherent stack.
    • Design for reliability, performance, and scale — what you build today must hold as the company grows 5–10x.
    • Eliminate data silos. Build clean data pipelines that maintain a single source of truth across systems.
    • Own your services in production: monitoring, alerting, incident response, and post-mortems.
  • AI & Automation:
    • Build AI/LLM-powered features into internal workflows — automating approvals, knowledge retrieval, reporting, content generation, and operational processes.
    • Move fast from prototype to production. You know the difference between a demo and a system that works at scale.
    • Stay current on emerging AI capabilities and proactively identify where they unlock step-change improvements in internal productivity.
  • Collaboration & Influence:
    • Work directly with business stakeholders to understand pain points and translate them into technical solutions. You don’t wait for a spec — you help shape it.
    • Pair with and mentor junior engineers. Raise the technical bar through code reviews, design reviews, and leading by example.
    • Influence technical direction: propose architectural improvements, challenge assumptions, and drive best practices across the team.

Job Qualifications:
  • 5+ years of professional software engineering experience, with meaningful time spent building internal tools, platforms, or business systems.
  • Strong full-stack or backend engineering skills. Proficient in at least one of: Python, Go, TypeScript/Node.js, or Java.
  • Solid understanding of cloud infrastructure (GCP/AWS/Azure), containerisation (Docker/Kubernetes), CI/CD pipelines, and modern DevOps practices.
  • Hands-on experience building and maintaining API integrations between third-party SaaS platforms (e.g., Workday, Salesforce, Slack, NetSuite).
  • Strong data fundamentals: relational databases, data modelling, ETL/ELT pipelines, and working knowledge of SQL.
  • Comfort with ambiguity. You can take a vague business problem, break it down, and deliver a working solution without heavy hand-holding.
  • Clear communicator who can explain technical tradeoffs to non-technical stakeholders.
Nice To Have:
  • Experience with workflow orchestration tools (Temporal, Airflow, Prefect) or integration platforms (Workato, Tray.io, MuleSoft).
  • Frontend experience with React, Next.js, or equivalent modern frameworks.
  • Familiarity with HRIS, ERP, or people systems data models and processes.
  • Experience at a high-growth or AI-native company.
  • Contributions to developer experience tooling, CLIs, or internal SDKs.
  • Experience building or integrating AI/LLM-powered features — not just experimenting, but shipping to real users.

Job Details:
  • Job Type: Direct Hire
  • Pay Range: Market Rate
  • Location: Fully Remote.
