Job summary

The Ops Layer is seeking a Senior Full-Stack Product Engineer to partner with the founder and turn execution methodology into production-grade software. You will span the stack from front-end workflows to backend services and APIs, including LLM-powered inference pipelines and human-in-the-loop review systems.

Expect to tackle architectural decisions, security, testing, observability, and the evolution of the product, with Mumbai-based preference and exceptional remote candidates considered.

Qualifications

• Proven full-stack engineering experience across frontend, backend, APIs and databases.
• Ability to ship production-grade software end-to-end, not just features.
• Strong JS/TS skills with React/Next.js or similar frameworks.
• Solid backend architecture: data modeling, auth, API design, secure data handling.
• Experience integrating LLMs/AI into real products with clear boundaries.
• Knowledge of reliability: testing, observability, retries, idempotency, debugging.
• Comfort translating ambiguous problems into clean architecture decisions.
• Experience with Supabase/Postgres and cloud infra is a plus.

Responsibilities

• Build front-end workflows and backend services across the stack.
• Design relational data models, APIs, and secure data handling.
• Develop LLM-powered inference pipelines and human-in-the-loop systems.
• Ensure auditable inference history and production reliability.
• Collaborate with the founder on architecture, security, and testing.

Job description

Company Description

The Ops Layer builds execution systems for fast-scaling companies, helping founders and operators move from chaos to structured momentum. The team designs and installs operating systems that clarify decision-making, ownership, accountability, leadership cadence, and cross-functional execution flows. Core offerings include rapid diagnostics sprints, full Execution OS installations, strategic program leadership for high-stakes initiatives, and embedded delivery partnerships. The company works globally across APAC, EMEA, and North America and is trusted by leaders at organizations such as SolarWinds, Google, and Unilever. Engagements are productized, outcome-focused, and built for businesses where speed is outpacing internal coordination, with execution—not presentations as the primary deliverable.

Role Description

The Senior Full-Stack Product Engineer will work directly with the founder to turn The Ops Layer’s execution methodology into production-grade software. You’ll build across the stack: front-end workflows, backend services and APIs, relational data models, LLM-powered inference pipelines, human-in-the-loop review systems, and secure handling of sensitive organizational data.

The harder problems are architectural rather than cosmetic: deciding where deterministic logic ends and model judgment begins, resolving inconsistent descriptions of the same organizational decision, preserving auditable inference history as evidence changes, and building systems that remain reliable as the product evolves.

You’ll have meaningful input into architecture, security, testing, observability and technical direction.

This is a contract role, with Mumbai preferred and exceptional remote candidates considered.

Qualifications

• Strong full-stack product engineering experience across modern front-end frameworks, backend services, APIs, and relational databases.
• Proven ability to design and ship production-grade software end to end, not just implement isolated features.
• Strong JavaScript/TypeScript skills; experience with React/Next.js or comparable modern web frameworks.
• Solid backend architecture experience, including data modelling, authentication, authorization, API design, and secure handling of sensitive data.
• Experience integrating LLMs or AI APIs into real products, with a clear understanding of where deterministic logic should end and model judgment should begin.
• Experience building human-in-the-loop workflows, review systems, audit trails, versioned records, or other systems where traceability matters.
• Strong understanding of reliability fundamentals: testing, observability, retries, idempotency, failure handling, and production debugging.
• Comfortable working directly with a founder to translate ambiguous operational problems into clean technical architecture and product decisions.
• Strong architectural judgment and willingness to challenge assumptions rather than simply execute tickets.
• Experience with Supabase/Postgres, cloud infrastructure, queues/webhooks, or workflow-heavy B2B SaaS products is highly beneficial.
• Prior experience with AI products, workflow systems, enterprise software, operations tooling, or decision-support systems is a plus.
• Degree in Computer Science, Engineering, or a related field is welcome but not required; demonstrated technical depth and shipped work matter more.
