PAR is seeking a highly skilled Sustaining Engineer to join the technical backbone of the Punchh platform. This engineering-led role ensures the health, stability, and scalability of Punchh's production systems, supporting the restaurant brands and their guests who rely on it every day. You will be hands-on in resolving complex production issues at the code level, conducting root cause analysis, and implementing architectural and process improvements to meet service-level objectives (SLOs) and service-level agreements (SLAs). You will work closely with Engineering, Product, DevOps, and Customer Success teams, and your findings will regularly be communicated onward to the restaurant brands we serve. Please note: this role requires sustained working overlap with North America business hours, and includes ownership of recurring daily and weekly operational duties described below. Please read the "How This Role Actually Works" section carefully before applying. Unleash Your Potential Punchh is a customer loyalty and engagement platform for restaurant brands. The majority of the issues you will investigate fall into these areas: • Loyalty campaigns — segmentation, mass gifting, recall and anniversary campaigns, scheduled sends, control groups, and campaign performance reporting. • Loyalty mechanics — points earning and expiry, redeemables, rewards balances, tiers, and guest-level data integrity. • Integrations — POS systems, online ordering providers, payment processors, and marketing/messaging platforms. • Platform reliability — database performance under campaign load, notification delivery, API availability, and authentication flows. Prior experience in loyalty, marketing automation, or restaurant technology is a significant advantage. Candidates whose background is purely generic backend or infrastructure work, without exposure to campaign or customer-data platforms, will find the ramp steeper. How This Role Actually Works Beyond project and escalation work, this role carries standing operational ownership. We want to be explicit about this, because it is a meaningful part of the week: • Daily monitoring and reporting — you will own the daily campaign load report and a forward-looking overload forecast covering multiple production stacks, and publish it to the engineering team each morning. • Alert triage ownership — you will be the first responder for automated alerts across campaign, worker SLO, and application error channels. Engineers and product teams will tag you directly and rely on your judgment to distinguish a genuine failure from expected noise. • Weekly operational communications — production maintenance summaries and technical updates for the Customer Success team. • Remediation execution — running and validating data-fix and bulk-gifting scripts against live production data, often affecting thousands to hundreds of thousands of guest records, with appropriate care, checkpointing, and verification. These duties do not stop when a project is busy. Reliability here comes from someone doing the unglamorous things consistently.
