Mus have expereince in Odoo , Redmine aand ROR
- 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
- Expert-level proficiency in Ruby on Rails, including production experience building or maintaining Redmine plugins or comparable Rails-based extensions

What you will do:
● Design and build features for our web applications — front end and back end, using Ruby on Rails, Python, JavaScript, and React
● Work across the stack: databases, APIs, and the plumbing that connects them
● Take a feature from first line to shipped — you'll touch every phase of the build, not just one slice of it
● Test for performance, security, and the edge cases that actually break things in production
● Work directly with the rest of the team on shared infrastructure, not off in a corner
● Push for better tools and approaches as the codebase grows, instead of settling for "it's always been done this way
What you need
● 0-1 years of professional experience building with Ruby on Rails, Java, Python, JavaScript/React, or Node
● Comfortable with JavaScript, HTML, CSS, and jQuery on the front end
● A real grip on data structures and algorithms — not just the interview-prep version
● Solid object-oriented design instincts
● You'd rather write simple, clean code than clever code
● Comfortable with relational databases day-to-day
● Working knowledge of NoSQL is a plus, not a requirement
● Some interest in the math and stats side of finance helps — you don't need to be an expert.
Also running in production here — OPTIONAL / NICE TO KNOW You won't be hired against this list. Prior exposure is a genuine plus, and you'll bump into these once you're in — but not knowing them isn't a blocker.

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
- Expert-level proficiency in Ruby on Rails, including production experience building or maintaining Redmine plugins or comparable Rails-based extensions
- Strong command of business processes across delivery, support, and operations — able to translate how a business runs into how a tool should behave
- Practical agentic development experience: MCP, LLM tooling, AI-assisted automation, or agent-orchestrated workflows in production
- Proven track record building plugins, modules, and extensions that survive product version upgrades, with disciplined API and integration design
- Commitment to clean, tested, production-grade systems — including when the author of the code is an agent
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
