Full-Stack Software Engineer
Join Harmony as a deployed full‑stack engineer for manufacturing customers in Mexico. Your first deployment will be in Torreón, where you will work on‑site with operators and plant stakeholders. After that, you may support additional customers in Torreón or other manufacturing regions across Mexico.
Location — In‑person deployment role; first assignment in Torreón, Mexico; future assignments may be elsewhere in Mexico.
Mission — We help factories eliminate paper, manual data entry, and disconnected systems, replacing them with intelligent workflows that learn directly from the floor. Our software connects machines, ERPs, and people in real time, turning tribal knowledge, production, and quality data into systems that run smoother, faster, and smarter.
About the role
You will relocate for deployments and work in person with operators and customer stakeholders to scope workflows, rapidly prototype, and ship production‑grade software for real manufacturing environments. In parallel, you will build reusable tooling and abstractions (SDKs, templates, adapters, CLIs, golden paths) that make future customer deliveries faster, safer, and more consistent.
Success is measured by customer outcomes (time‑to‑value, adoption, reliability) and platform leverage (reusable modules merged upstream).
Responsibilities
- Embed with operators and stakeholders to map workflows, define success criteria, and iterate from prototype to production directly on customer infrastructure.
- Build across the stack with Python, TypeScript, React, Postgres, and containerized services (Docker/K8s) using Terraform for infrastructure as code.
- Own the full life cycle: scoping, prototyping, hardening, deployment, documentation, enablement, and knowledge transfer.
- Operate and improve: instrument services, set SLAs and evaluations, optimize latency and reliability, and debug complex enterprise setups.
- Create monorepo‑friendly scaffolds (Turborepo/Nx patterns), code‑generation templates, and CI/CD blueprints for repeatable, high‑quality deployments.
- Ship internal SDKs and adapters for common systems (auth, data ingestion, messaging, observability), plus CLI tools to spin up new services quickly.
- Establish golden paths for linting, testing, release and versioning, and environment bootstrapping.
- Channel field learnings into the core Harmony platform, deciding when to customize and when to productize.
- Work with GTM and Sales teams to unblock integrations, activate accounts, and expand usage through tangible technical outcomes.
- Contribute documentation, runbooks, and training to enable both customer and internal teams.
Qualifications
- 2+ years building and shipping production systems with strong customer‑success fundamentals.
- Proficient in Python and TypeScript/React; comfortable moving across APIs, services, front end, and data.
- Hands‑on experience with Docker/K8s, Terraform, CI/CD, and observability in production environments.
- Experience integrating with enterprise systems (SSO/OIDC/SAML, data sources) under security and compliance constraints.
- Excellent communication with non‑technical stakeholders; thrives in ambiguous, customer‑facing, on‑site deployment work.
Preferred (Additional) Experience
- Prior forward‑deployed, solutions, or consulting experience on customer infrastructure.
- Monorepo expertise (Turborepo/Nx), trunk‑based development, semantic versioning, internal CLIs/codegen.
- Experience building developer platforms, SDKs, abstractions, templates, and golden paths.
- AI/LLM delivery experience: evaluation design, batching, latency optimization, and prompt/tool hygiene.
- Change management and training: enabling customer teams to adopt new systems.
How We Measure Success
- Time‑to‑value: speed from scoping to first production deployment.
- Reliability and performance: latency, uptime, and error budgets achieved in customer environments.
- Customer impact: usage growth, references, and expansion driven by deployed solutions.
- Platform leverage: number and impact of reusable modules, scaffolds, and tools reused across accounts.
Benefits & Perks
- In‑person full‑time deployment role; first assignment in Torreón, Mexico, with future deployments potentially elsewhere in Mexico.
- Deployed‑team support for on‑site work.
- Accommodation support if relocation is required for a deployment.
- Direct collaboration with the founders every day with full ownership.
- High‑trust, high‑intensity environment built on craft, speed, and impact.
