You'll champion and lead the build of the automation and data pipelines that power pricing, billing, and financial reporting across Telnyx's product portfolio.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>The Opportunity</strong></p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Our PCR squad owns the backend systems and pipelines behind pricing, margin reporting, and cost analysis across voice, messaging, wireless, and the rest of Telnyx's product portfolio. You'll work with complex Airflow DAGs, rate deck management, pricing APIs, and CDR/MDR data at scale.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">You'll own and develop services and pipelines that finance, sales, and product teams rely on every day to make pricing decisions, reconcile vendor costs, and report on the health of the business. You'll have the opportunity to make a huge impact by automating workflows that are currently manual, building self-healing pipelines, and bringing more rigor to how we manage pricing across a growing product set. You'll be part of a small, focused team where the work you ship is visible and consequential.</p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">Own and maintain complex Airflow DAGs for pricing automation, margin reporting, and cost analysis.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Build and manage rate deck pipelines across multiple product lines.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Develop and maintain pricing APIs and services in Python (async).</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Analyse CDR/MDR data to identify vendor discrepancies and drive refund and reconciliation workflows.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Build automated discrepancy resolution and self-healing pipelines.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Create and maintain financial reporting: monthly margin reports, negative margin alerts, and GP calculations.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Design and build new automation for quoting workflows.</li> </ul> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Who we're looking for</strong></p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">5+ years of professional Python experience, with strong async programming (aiohttp, asyncpg, FastAPI).</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Airflow production experience — you've built and maintained complex DAGs, not just run them.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">SQL fluency across PostgreSQL and analytical databases (Athena, BigQuery, or similar).</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Comfort working with financial and pricing data (margins, markups, cost basis, currency).</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Ability to read and debug Java services when needed.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">CI/CD experience with Docker, Jenkins, or GitHub Actions.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Strong troubleshooting skills — you can dig through logs, query databases, and trace data pipelines to find the root cause of a discrepancy.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Comfortable owning services and pipelines in production, including on-call responsibilities and incident resolution.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Comfortable using AI coding agents as part of your investigation workflow, while knowing when to rely on your own judgement.</li> </ul> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Bonus Points For</strong></p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">Go experience.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Telecom or CPaaS background (CDRs, termination rates, origination prefixes).</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Salesforce or CRM integration experience.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Experience with pricing engines or billing systems.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">You take a thoughtful approach to decision making, knowing when to move fast and when to optimise for the long term.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">You want to work in a fast-paced, product-driven environment.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">You keep up to date with the latest technologies and patterns, and enjoy sharing what you've learned.<br><br></li> </ul> <h5>#LI-IRELAND&nbsp;</h5> <h5>#LI-AMSTERDAM</h5><div class="content-conclusion"><p>&nbsp;</p> <p>&nbsp;</p></div>
