Senior Full-Stack Engineer: Infrastructure & Distributed Systems

Build the infrastructure layer powering enterprise AI automationEnterprise software integrations are still painfully fragile: workflows break silently, APIs fail unpredictably, systems drift out of sync, and teams waste countless hours maintaining infrastructure that was never designed for real-time operations at scale. For years, most data companies focused primarily on analytics because the underlying integration and operational tooling was too broken, unreliable, or difficult to use for powering critical business operations in production.You can think of Stacksync as Zapier for enterprise systems, but built for real-time and mission-critical operations at scale.Our Platform Powers Mission-critical Operationssupply chainsmanufacturerslogistics companieshealthcare organizationsfinancial operationsecommerce businessesenterprise sales organizationsWhen our systems run, orders move, invoices sync, warehouses operate, contracts renew, revenue gets recognized, and business workflows execute in real time.What Makes This Role DifferentWe Solve Difficult Distributed Systems Problems Involvingreal-time synchronizationqueues and event-driven systemsdistributed workflowslarge-scale data movementAPI orchestrationPostgres-heavy architecturesunreliable third-party systemsEDI and enterprise connectivityhigh-throughput infrastructureThis is not a typical CRUD SaaS role.We are building a category-defining infrastructure company and are looking for strong product-minded engineers who want ownership over real systems, internal platforms, and infrastructure products from architecture to production operations.This Opportunity IS for You IfYou are a true full-stack engineerYou enjoy difficult engineering problemsYou care deeply about system quality and maintainabilityYou thrive in fast-moving, high-ownership environmentsYou enjoy scaling distributed systemsYou think like a product owner, not just an implementerYou naturally take initiative without waiting for permissionYou want to build infrastructure used by real enterprise customers that power critical operationsYou are extremely ambitiousYou want to work with a very strong technical teamThis Opportunity IS NOT for You IfYou only enjoy building simple CRUD applicationsYou dislike operational complexityYou need highly structured environmentsYou avoid ownershipYou prefer maintaining existing systems over building new onesYou think shipping one feature per day is “fast”You are uncomfortable with ambiguity or pressureYou believe scaling infrastructure is mostly solved alreadyWhat You’ll Work OnExamples Of Problems We Solvereal-time bi-directional synchronizationdistributed retries and failure recoveryqueue scaling and orchestrationAPI rate-limit managementlarge-scale Postgres systemsworkflow execution enginesobservability and debugging toolingschema propagation systemsenterprise connectivity infrastructurehigh-volume data movement pipelinesTech StackPythonReactPostgresGCP / AWS / AzureDistributed queues and workflowsWhat We Value MostOwnershipTechnical depthExecution speedProduct thinkingCommunication clarityReliabilityAmbitionFast learning speed⚠️ Apply By Answering ⚠️What excites you about building infrastructure systems at Stacksync?
