Your Role
You'll join the team building workflow software for one of the studio's clients: a live product that needs new workflow features while the existing ones keep running.
The client's own engineers commit to the same repo, so every new table, permission and workflow goes in next to code someone else is changing.
The weight is on the server side, from the SQL database on Azure up through the API, and you also build the React and TypeScript screens that sit on top.
AI coding tools draft most of the specs, tests and migrations.
You direct them, read every diff line by line, and answer for what merges.
If you'd rather write most of the code by hand, this probably isn't the right seat.
You report to the studio's leadership and work day to day with the lead developer and the product manager, who sets the acceptance criteria for each sprint.
Success means delivering four to five features per two-week sprint, each verified before merge, and owning one area end to end (such as the task engine or the legacy migration) without breaking a live feature.
Extend the production SQL database on Azure with new tables, permissions and versioned recordsWrite the server-side workflow rules: state machines, approval gates and independent review stepsEnforce role-based access by company and assignment at both the database and the APIBuild the audit log, stale-write protection and idempotent endpoints so a retry never duplicates dataBuild the React and TypeScript work queues, bulk assignment tools and dashboardsIntegrate email, SMS and file storage providers, and design the sync APIs the mobile application callsWrite migrations from legacy sources, with reconciliation reports and a duplicate review stepBreak each sprint's scope into small PRs and verify every acceptance criterion before merge
You Bring
4+ years building full-stack web applications and releasing them to productionExperience working in a codebase you didn't write, learning its conventions before changing itHands-on work on workflow software where different user roles see different data, with approvals, task queues or state machines and an audit log or versioned historyReact, TypeScript and SQL on Azure, including schema design and migrationsDaily use of Cursor, Claude Code or a similar AI coding tool on production work, with tests and CI behind itClear written and spoken English: PRs that say what changed, why, and how it was tested, and tradeoffs explained to another team's engineersExperience delivering in fixed-scope sprints with branches, code review and feature flags
Bonus Points
Work in a regulated setting such as finance, health or insuranceA migration from a legacy system, with reconciliation and duplicate reviewTime as an outside vendor committing to a client's repoProject rules, custom prompts or agent setups for AI coding tools that your team adoptedSpanish, since the platform is bilingual
What's Offered
Fully remote contractor role from LATAM,



full time at about 40 hours a weekCore hours in US time zones, so your day overlaps with the lead developer and the product managerAn area of the product to own end to end, with your schema designs reviewed by the lead developer and the client's engineersA team where AI-first delivery is already the daily routine, with tests, CI and feature flags as part of the normal processA start in early November
Interview Process
Intro Call: 30 minutes with atomic HR on your background and goalsLeadership Screening: A short call, possibly with an async part firstProduct and Developer Conversation: How you take features from acceptance criteria to mergeTake-Home Test: One feature like the real scope, built and checked

About the Role
We are seeking a Senior Software Engineer to support and execute a critical observability migration.
In this role, you will lead the transition of our application and infrastructure telemetry from New Relic to a modern, OpenTelemetry (OTel)



Collector-based architecture.
You will be responsible for re-instrumenting applications, updating infrastructure manifests, validating telemetry outputs, and ensuring seamless monitoring coverage across our high-scale ecosystem without compromising operational visibility.
Key Responsibilities
Migrate existing application instrumentation, tracing, and telemetry configurations from New Relic to OpenTelemetry.Update YAML configuration files, environment variables, and deployment manifests according to established architecture standards.Execute unit tests and validation suites to verify that telemetry is accurately generated, transformed, and exported to target backends.Perform telemetry gap analysis, comparing existing New Relic data against OTel outputs to identify missing traces, metrics, logs, or resource attributes.Assist in updating dashboards, monitoring documentation, and troubleshooting guides to reflect the OTel architecture.Investigate telemetry collection and export errors, identifying root causes and collaborating with core platform engineers on complex edge cases.Maintain clear tracking and reporting of implementation progress, edge cases, and potential migration risks.
Requirements
Must-Have
Proven experience in software engineering with proficiency in at least one modern language (Java, Python, Go, or JavaScript/TypeScript).
Hands-on experience with OpenTelemetry (OTel) concepts, including distributed tracing, metrics, logs, and OTel Collector configurations.Deep experience with cloud observability paradigms and transitioning off legacy platforms like New Relic.Solid understanding of HTTP, APIs, environment-based configurations, and reading/modifying complex YAML/JSON manifests.Strong background in software testing, debugging, log analysis, and validating high-cardinality telemetry data.Familiarity with modern software delivery workflows (Git, PRs, CI/CD pipelines).
Nice-to-Have
Experience operating or configuring OTel Collectors in Kubernetes or containerized environments.Knowledge of FinOps and cost-optimization strategies related to telemetry ingestion rates.
Key Deliverables & Success Criteria
Execution: Successfully updated application instrumentation, validated OTel Collector configs, and verified end-to-end telemetry delivery to designated backends.Documentation: Updated technical documentation, migration checklists, and runbooks.Quality & Continuity: Zero removal of critical monitoring coverage during the migration window, with all pull requests passing automated tests and code reviews.
What We Offer (Contractor)
Contractor agreement with payment in USD.100% remote work in an international setting.Access to Argentine public holidays.Direct involvement in modernizing core platform observability for a high-growth fintech ecosystem.Professional development, learning platforms, and referral programs.
