Senior Software Engineer, Pipelines

Softline Solutions is a full‑service digital marketing agency based in Southern California that helps small and mid‑sized businesses grow online by increasing visibility, generating leads, and boosting sales. They build tailored, data‑driven campaigns across key digital channels and manage everything from strategy to execution and reporting. The goal is measurable growth, not buzzwords. Some companies include Closets by Design, Canada Dental Group, travel companies, and merchandise distribution companies. About the Role Softline Solutions manages complex marketing programs across a portfolio of clients. We are building a multi‑tenant data platform that serves as the single source of truth for marketing data across every client and program. At its center is a universal schema that stores cross‑organization, cross‑company data in one system of record. You will own this platform end‑to‑end: the API ingestion layer for both self‑service third‑party connectors and proprietary first‑party client data, the transformation pipelines, internal and client‑facing dashboards, agentic automation, and monitoring infrastructure. You report directly to a board member and work across senior leadership to deliver validated visibility fast. What You'll Do A massive central schema normalizing cross‑client, cross‑org marketing data into a canonical model with multi‑tenant isolation, versioning, and cross‑client benchmarking. A self‑service connector framework: new clients authenticate and connect their own third‑party platforms (Meta, Google, LinkedIn, HubSpot, Salesforce, GA4, Shopify, etc.) without engineering involvement. A first‑party data ingestion API where clients push proprietary data (CRM exports, offline conversions, custom events) through validated transformation pipelines into the universal schema. Internal and client‑facing dashboards: white‑labeled, permission‑scoped, self‑service, blending first‑party and third‑party data into unified marketing attribution views. Agentic automation: AI agent orchestration pipelines (agent‑of‑agents patterns) that automate data validation, anomaly detection, report generation, and cross‑pipeline coordination. Full observability: alerting, health checks, data freshness SLAs, and self‑healing mechanisms across the platform. Qualifications Expert in abstraction and system design: you take messy, multi‑source data landscapes and design clean schemas, APIs, and interfaces that make them tractable at scale. Deep marketing data fluency: attribution models (MTA, MMM, last‑touch, first‑touch), conversion tracking, UTM structures, ad platform APIs, cross‑platform data reconciliation. Strong product and productization instincts: multi‑tenant architecture, user auth (OAuth, RBAC, SSO), self‑service onboarding, schema mapping. Cloud architecture fluency (AWS preferred): serverless, containers, managed databases, API gateways, IAM. AI‑native and agentic: you build with Claude, Cursor, and similar tools daily. You understand agent orchestration, agent‑of‑agents patterns, and programmatic automation of complex multi‑step workflows. You are a $50K/year AI user because it makes you a genuine 10x builder. Data validity obsessive: you understand testing metrics, data quality frameworks, validation layers, and build systems that prove their own correctness. Exceptional communicator: you work directly with senior leaders, client teams, and operations staff, translating technical complexity into clear visibility and actionable insight. Requirements 5+ years in software, data, or product engineering; track record shipping multi‑tenant data platforms. Experience designing large, normalized schemas storing data across multiple organizations in a single system. Experience building self‑service integration frameworks and first‑party data ingestion APIs. Pipeline orchestration (Airflow, Dagster, Prefect) and dashboard tooling (Retool, Metabase, Looker, or custom). OAuth 2.0, JWT, RBAC, SSO/SAML. Demonstrated heavy AI tool usage including agent orchestration and agentic automation (we evaluate this directly). Marketing technology or agency experience strongly preferred. How to Apply Send your resume along with one of the following: A link to a data product or platform you built, with context on architecture decisions. A 1‑page write‑up on how you would build a unified, multi‑tenant marketing data platform for a multi‑client agency. Your AI tooling setup: what you use, how much you spend, and how it changes your output. The pay range for this role is: 160,000 - 250,000 USD per year (Softline HQ) #J-18808-Ljbffr
