Technical Support Engineer I provides first-level technical support for Planview KeyedIn (enterprise PPM) Customer Care customers and internal employees, serving as the primary point of contact for a defined set of accounts and cases. In this role, you will independently resolve standard cases across user and license administration, project and resource management, reporting, data operations, and integration workflows, while investigating root causes and documenting durable solutions.

You will escalate complex or defect cases appropriately — acting as a liaison between customers and the Development and Cloud Operations teams — and guide customers on the product's proper use and best practices. As you grow, you will take on increasingly complex problems end-to-end and mentor Associate Technical Support Engineers, contributing to a high-performing, collaborative team.

•   Understanding of identity and access management concepts (SSO, OAuth, RBAC, SAML).

•   Knowledge of the Planview product ecosystem, particularly KeyedIn or other PPM solutions.

•   Relevant technology certifications (Microsoft, AWS, ITIL, or similar).

Knowledge, Skills & Abilities

•   Willing to accept and adapt to change, showing flexibility and recovering relatively quickly from setbacks.

Growth Opportunity

This is a product-focused role with learning, responsibility, and growth opportunities. Performance-based growth review will be considered after the initial period based on ownership, consistency, and delivery quality.

Job Responsibilities:

• Understand the problem first-hand. Spend time with the product owner or the ops team that has the problem, and see how the work happens today rather than working from a requirements document alone.
• Design, build and ship end to end. API and data model through to the screen the user touches. Backend and frontend are both yours.
• Take it to production and keep it healthy. Deploy it, monitor it, and act on what the monitoring tells you. Errors, latency, failed jobs and data quality are yours to watch — and ideally you spot the issue before someone reports it.
• Be mindful of what it costs to run. Every service you deploy carries an infrastructure bill. Think about instance sizing, storage, query patterns, log volume and the cost of third-party API calls before you ship, and raise it early when something is likely to get expensive.
• Integrate cleanly with vendors and partners. A large part of our platform is third-party: bureaus, banks, KYC providers, payment rails, co-lenders. Working well with vendor teams, reading their documentation carefully and handling their failure modes gracefully is core to the job, not a distraction from it.
• Be accountable for what you commit to. Give estimates you believe in, flag slippage early, and keep the status visible.
• Leave it documented. A runbook, an API contract, and a short note on any non-obvious decision, so the next engineer — or the next agent — can pick it up without you.
• Build securely by default. We are a regulated lender. Customer and credit data handling, access control, audit trails and PII discipline are part of the definition of done, not a later hardening pass.

Skills Required:

JavaScript , TypeScript , Node.js , API Design , Relational Data Modelling , SQL , Vendor Integration , Third-party Integration , Authentication , Retries , Idempotency , Webhooks , Rate Limits , Queues , Background Jobs , Scheduled Work , React , Component Design , State Management , CSS , Git , CI/CD , DevOps , Containers , AWS , Monitoring , Cost Awareness , Troubleshooting , Documentation , Security

Candidate Attributes:

• Strong JavaScript/TypeScript and Node.js.
• You can design an API, not only implement one.
• Relational data modelling and SQL you can reason about — indexes, query plans, transactions, migrations on live tables.
• Vendor and third-party integrations, done well: authentication, retries, idempotency, webhooks, rate limits, sandbox-to-production rollout, and reconciliation when the other side fails mid-flow.
• Comfort working directly with a vendor's technical team to get an integration over the line.
• Queues, background jobs and scheduled work, including what happens when a job runs twice.
• React with TypeScript.
• Component design, state management, forms that hold up under real user behaviour.
• Enough CSS and layout sense to build a clean screen without a pixel-perfect design handed to you.
• Performance and correctness on the browser side: loading states, error states, the ugly edge cases.
• Tests you actually write. Shipping agent-assisted code at volume only works if the test coverage holds it up.
• Git discipline, CI/CD, and enough DevOps grounding to be self-sufficient: containers, environment configuration, pipelines, deployments and rollbacks.
• You do not need to be an SRE, but you should not need one for routine work.
• AWS fundamentals: how your service runs, scales and fails.
• Instrumenting what you build — logs, metrics, alerts — so problems surface on a dashboard rather than in a customer complaint.
• Reading monitoring output and acting on it: triaging an alert, finding the root cause, and closing the loop with a fix or a tuned threshold rather than muting it.
• An eye on infrastructure cost. Knowing roughly what your service costs to run, spotting the query, log stream or API call pattern that is quietly expensive, and factoring that into design decisions.
