Experience Level
The Staff Software Craftsperson is a technical leadership role equivalent to an SDE-4/SDE-5. We are looking for seasoned engineers with 8+ years of hands-on experience who have transitioned from building great software to shaping the engineering culture and technical strategy of an entire organization.
As a Staff-level crafter, your focus shifts from solving well-defined problems to identifying and solving the most complex, ambiguous technical challenges that impact our clients and our internal engineering standards.
What You’ll Do as a Software Craftsperson
Technical Vision & Architecture: Lead the architectural direction for complex, large-scale systems. You will balance the immediate needs of the business with long-term system health, ensuring our solutions remain simple, scalable, and resilient.
Engineering Excellence at Scale: Champion disciplined engineering practices (TDD, Pair Programming, CI/CD) across multiple teams. You don’t just follow the bar; you raise it by introducing better patterns and tooling.
AI Strategy & Mentorship: Drive our AI-native development model. You will experiment with and define how we use AI to accelerate the SDLC, ensuring the team uses these tools to enhance—rather than replace—deep technical judgment.
Cross-Team Leadership: Act as a force multiplier. You will mentor senior engineers, conduct high-impact code reviews, and foster a culture of continuous learning and craftsmanship.
Strategic Client Partnership: Work as a technical consultant for high-stakes client engagements, translating vague business goals into robust technical roadmaps and navigating complex stakeholder environments.
Systemic Problem Solving: Beyond resolving production issues, you identify "class-level" problems in our infrastructure or codebase and implement systemic changes to eliminate them permanently.
Requirements
What We're looking for
8+ years of experience building and maintaining high-scale production systems.
Mastery of Fundamentals: Expert-level understanding of object-oriented design, functional programming, and system architecture (Microservices, Event-driven, etc.).
Polyglot Mindset: High proficiency in Ruby on Rails and React/Angular, with the proven ability to architect solutions across multiple tech stacks (Python, Go, etc.) as needed.
Influence without Authority: Demonstrated ability to lead through persuasion and technical excellence rather than just hierarchy.
Advanced AI Collaboration: Deep experience integrating AI into a professional workflow to explore architecture, automate toil, and peer-review logic.
Proven Ownership: A track record of taking a project from a nebulous idea to a successful, maintained production system.
Communication: Exceptional ability to explain complex technical trade-offs to non-technical stakeholders and executive leadership.
Clear thinking and strong problem-solving ability, with the capacity to break down complex problems into simple, well-structured solutions.
A strong sense of ownership — you take responsibility for outcomes, care deeply about quality, and are not comfortable shipping work that does not meet your standards

Core Responsibilities
Operational Tools Architecture & Feature Planning
- Own the feature roadmap for operational tools — Odoo, Redmine, GitHub, and adjacent systems — from business-process discovery through design, planning, and phased delivery
- Serve as the subject-matter expert on how business processes (deal onboarding, delivery, support, finance, engineering operations) map onto tool capabilities, and where the gaps are
- Design cross-tool workflows and integrations so that work items, code, and business records flow between systems as one coherent operational fabric
Agentic Implementation & Modernization
- Design agent-operable surfaces on each tool: typed, secure APIs, Model Context Protocol (MCP) servers, and webhook-driven automation that let AI agents read, create, and resolve operational work safely
- Lead incremental modernization of legacy tool deployments — upgrading versions, retiring brittle customizations, and replacing manual processes with agentic workflows without disrupting live operations
- Optimize agentic loops that operate on the tools for cost, speed, and integrity, with guardrails, audit trails, and human-in-the-loop checkpoints where they matter
Plugin & Extension Engineering
- Architect and build Redmine plugins in Ruby on Rails, Odoo modules, and GitHub Apps/Actions that extend the products cleanly rather than forking them
- Engineer enhancements to be upgrade-safe across product versions — tracking upstream releases, isolating customizations behind stable interfaces, and planning migration paths
- Prioritize contract-first API design between human intent, agent execution, and the underlying tools
Governance & Quality Control
- Act as the architectural reviewer for changes to Central tooling, including AI-generated pull requests and agent-authored configuration
- Mandate testing and characterization coverage around customizations so upgrades and agentic changes land deterministically
- Establish operational standards — access, data integrity, observability — for agents acting inside business-critical systems
Required Qualifications
- 10+ years in software engineering, business-systems architecture, or platform engineering, with deep SME knowledge of operational tools such as Odoo, Redmine, GitHub, or comparable ERP/ITSM/DevOps platforms

Preferred Qualifications
- Python and Odoo module development experience; PostgreSQL fluency
- Experience modernizing or migrating legacy tool deployments across major versions
- Background in SaaS transformation, scale-up, or PE-backed environments
