As our reach expands, we are building for a step-change in scale, and for opportunities ranging from more relevant rewards and marketer intelligence to new commerce and distribution models.\nAbout the Role\nThe Customer Experience (CX) team owns the systems that power Kard's end-to-end rewards experience: transaction matching and the cellar pipeline, offer ingestion and delivery (including partner integrations like Rewards Network and SEATED), the cell-based routing architecture, and the Support API that keeps our internal and partner-facing tooling running. As a Senior Software Engineer II, you'll operate at the center of this - designing and building the services that ingest, match, and settle transactions at scale, while helping the team raise its bar on operational readiness, testing, and documentation.\nThis role reports into the CX engineering team, with a strong focus on our issuer and partner-facing surface area, working alongside Support, Design, and Product through Kard's Shape Up-based pitch cycle. You'll drive pitches end-to-end, participate in on-call, and help the team keep pace with a fast-growing transaction volume and issuer surface.\nResponsibilities\nArchitect and build scalable services across transaction matching, the cellar pipeline, and offer ingestion - new work defaults to Go and Postgres; existing services are a mix of TypeScript and MongoDB.\nOwn features end-to-end through Kard's Shape Up cycle: discovery, pitch writing, implementation, testing, and production rollout, including a written launch/rollback plan for anything touchingtransaction or offer data.\n\nActively participate in on-call, incident response, and IOC (interrupt/on-call) triage; drive root-cause fixes rather than one-off patches (e.g., ingestion validation gaps, UID/timestamp mismatches, Datadog alertcoverage).\n\nStrengthen our issuer/client-facing APIs and SDKs - reliability, clarity, and self-service - so partners and Support can resolve more issues independently, reducing engineering escalations.\nLead by example: make decisive technical calls and foster collaboration across Product, Design, and Engineering to keep the team moving toward CX's strategic goals.\nChampion enhancements to our tech stack, methodologies, and standards - authentication, rate limiting, deployment, observability, error handling, and test coverage (unit, integration, end-to-end) -with an eye toward resilience, agility, and quality, not just shipping speed.\n\nMentor engineers, contribute to design and architecture discussions, and help the team consolidate or deprecate legacy/overlapping services rather than letting them accumulate.\nWrite clear documentation and playbooks (local dev setup, deployment, troubleshooting) so ownership doesn't stay concentrated with one or two people.\nDesired Skills\nExpert programming skills in Go and/or TypeScript, with experience building scalable, secure, high-performance backend services.\nSolid experience with distributed systems, event-driven architectures (SQS, Temporal), and both relational and document databases (Postgres and MongoDB).\nProficiency with AWS and Infrastructure-as-Code (Terraform), including container technologies (Kubernetes/EKS) and serverless components (Lambda).\nExperience working on transaction-processing, matching, or ingestion pipelines where correctness and idempotency matter.\nComfort leading a technical project from discovery through production rollout, including writing clear specs and driving cross-team collaboration (e.g., with Support, Data, or partner integration teams).\nSkilled with agentic software development - using AI tools (e.g., Claude Code, Codex) to plan and implement complex features, not just autocomplete - while still owning the design and quality of the result. \nCommitment to fostering an inclusive, collaborative engineering culture.\nU.S. core business hours availability and willingness to travel for company meetings.\nBonus Points\nExperience with card-linked offers, loyalty, fintech, or another transaction-intensive marketplace.\nExperience with partner data ingestion (file-based or API) and the validation/monitoring needed to run it reliably in production.\nFamiliarity with Cognito-based auth, API gateway enforcement (e.g., Envoy), or claims-based authorization.\nExperience with Databricks or a similar data platform, and with migrating services from a legacy stack (e.g., Databricks to Postgres/Lakebase) without disrupting production.\nContributions to the tech community or open-source projects.\nPast success in startup settings, and a track record of empathy, collaboration, and productivity in remote work.\nCompensation\nUnited States: $160,000 - $190,000 USD\nArgentina: $120,000 - $140,000 USD\nWhy Join:\nKard recognizes the unique value each of us brings to our collective success. As part of our remote-first team, you'll have the autonomy to influence our trajectory, actively contributing to the growth of our business and the evolution of our company culture. By embodying our core values of Initiative, Openness, and Humility, you will not only witness but directly foster an inclusive and dynamic work environment, from the executive level down.\nOur competitive benefit plan includes:\nFlexible PTO, with a minimum requirement to take one day off a quarter, ten days a year, promoting mental well-being\nObservance of 11 Federal Holidays, plus an additional day each for Black Friday and Christmas Eve (US employees only)\nHealth, Dental and Vision Insurance\n401k with employer match (US employees only)\nCoworking space and WFH setup reimbursement\nCompany Offsites for planning, team-building, and networking\nKard is an equal opportunity employer and we actively encourage applicants of all genders, backgrounds, and experiences to apply.
