    What You’ll Work On

    You will help build and evolve the internal engineering foundation that powers large-scale development. This role sits at the core of developer productivity, build systems, and infrastructure tooling — impacting how hundreds (or thousands) of engineers ship code every day.

    What You’ll Do

    • Architect and develop scalable Golang-based libraries, CLI tools, and internal platforms that streamline and standardize developer workflows.
    • Own and evolve critical parts of the build ecosystem — dependency management, caching layers, compilation pipelines, and CI/CD integrations.
    • Improve performance, reliability, and developer experience across large monorepos and distributed engineering environments.
    • Drive system-level optimizations through profiling, debugging, and concurrency improvements in Go.
    • Partner with Infrastructure, DevOps, Security, and Engineering Productivity teams to design resilient, scalable architecture.
    • Identify systemic bottlenecks in development processes and replace them with automated, high-leverage solutions.
    • Lead root cause analysis for build or tooling failures and implement long-term architectural fixes.
    • Raise engineering standards through thoughtful code reviews, documentation, and best-practice advocacy.

    What Makes You Strong in This Role

    • 5+ years of deep Golang experience, particularly in infrastructure software, build tooling, or backend libraries (not just product APIs).
    • Strong understanding of build systems, monorepo environments, and source control internals.
    • Hands-on experience with performance profiling, system-level debugging, and concurrent programming in Go.
    • Track record of building or contributing to internal platforms, CI pipelines, or open-source tooling.
    • Deep familiarity with CI/CD automation and Linux-based development environments.
    • Confidence working close to the system layer — scripting, debugging, optimizing.
    • Clear communicator who values documentation and scalable engineering processes.

    Nice to Have

    • Experience with large-scale build tools (Bazel, Buck, Pants, or similar).
    • Familiarity with Git internals and repository lifecycle optimization at scale.
    • Background in developer productivity or internal platform engineering.
    • Contributions to open-source Go or infrastructure projects.
    • Exposure to static analysis, security tooling, or automated code review systems.
    • Experience in enterprise-scale engineering environments.

    This Role Is Likely Not a Fit If

    • Your Go experience is limited or focused only on web/API development.
    • Your background is primarily frontend, full-stack, or enterprise Java applications.
    • You haven’t worked on infrastructure-level or system tooling projects.

    We are currently hiring an expert-level WordPress developer to help out on our project Booking Agent Info (Bookingagentinfo.com). We currently have 1 WP developer, and looking to bring on an additional developer to help us finish urgent work.

     

    We have 3 sites in which we need help building features for. These are our products.
     

    This is not a standard WordPress role. We’re looking for someone with deep technical ability who can work across databases, write and integrate APIs, and develop advanced custom solutions—not just tweak templates. You should have experience building and scaling complex platforms beyond the basics of WordPress.
     

    We are looking for someone who is ready to push hard, work with urgency, and take real ownership over what they build. If you’re someone who thrives in fast-paced environments, takes initiative without being asked, and wants to help drive a product forward—not just complete assigned tasks—this could be a great fit.

    • Hard Worker with Drive: You're not just looking for a 9–5 gig. You’re driven, committed, and not afraid to put in long hours when needed to help us hit important goals. You have the mindset and energy to push through product sprints and build something meaningful.
    • Deep Technical Expertise: You go far beyond WordPress basics. You're comfortable working with PHP at a high level, managing and optimizing large databases, and building as well as integrating APIs from scratch.
    • Proactivity and Initiative: You don’t wait for permission—you spot issues, propose improvements, and start building better solutions on your own.
    • Product-Focused Mindset: You think beyond code and care about the user experience and business outcomes. You contribute thoughtful feedback that improves the product.
    • Independent and Reliable: You don’t need to be micromanaged. You take ownership of your work and follow through with accountability.
    • Thorough and Detail-Oriented: You test your own work, troubleshoot edge cases, and take pride in delivering clean, functional code.
    • Experience Creating Multilingual Sites: You have experience making a site multilingual using plugins like Polylang or WPML
    • Experience with Symfony is a plus
