Responsibilities include enforcing API contracts, driving serverless solutions on AWS, ensuring data standards and security, mentoring team members, and translating commercial requirements into technical specifications. Candidates should have over 7 years of backend development experience, mastery of AWS, and a strong understanding of API design and microservices, with AdTech experience as a bonus.
DanAds
You are not just building features; you are building the Factory. DanAds is shifting to a "Platform-First" architecture. We are moving away from monolithic, client-specific codebases to a standardized, API-driven ecosystem. As the Platform Lead Back-End Developer, your mission is to design and build the high-performance, reusable Microservices (Identity, Booking, Reporting, AI) that power our entire product suite. You will act as the "Technical Guardian" of the backend, ensuring that every service we ship is multi-tenant, serverless, and strictly decoupled from the frontend. Technical Leadership • Enforce the Contract: You are the gatekeeper of the API. You will define and maintain strict OpenAPI specifications. No code is written until the contract is signed. • Serverless-First: Drive our FinOps strategy by architecting solutions on AWS Serverless (Lambda, API Gateway, DynamoDB, EventBridge) to ensure a "Scale-to-Zero" cost model. Platform Governance • The Reusability Filter: You will ruthlessly reject "snowflake" logic. If a Product Team asks for a specific feature, your job is to abstract it into a generic capability that serves 10+ clients. • Data Standards (AdCP): Enforce the Ad Context Protocol (AdCP) across all data models. You ensure our data speaks the universal language of AdTech. • Security & Tenancy: implement strict Logical Isolation patterns. You ensure that Tenant A can never touch Tenant B's data, enforcing policies via JWT and Row-Level Security. Team Mentorship & Culture • Lead by Code: You are a hands-on leader. You write the "Golden Path" templates and libraries that other developers use. • Review & Refine: Conduct rigorous code reviews to ensure adherence to our NFRs (Non-Functional Requirements) regarding latency (<200ms), availability (99.99%), and observability. • Bridge the Gap: Translate the CPO's commercial requirements into technical specs. You turn "We need better sales" into "We need a Recommendation Engine API." What you bring to the table • Senior Engineering Experience: 7+ years in backend development, with a deep focus on API design and microservices. • AWS Native: Mastery of the AWS ecosystem, specifically Lambda, DynamoDB, EventBridge, and CloudFormation/Terraform. You don't just use the cloud; you architect for it. • API Design Pro: You dream in JSON. You have extensive experience designing RESTful/GraphQL APIs and treating them as products (Versioning, Documentation, Backward Compatibility). • The "Platform Mindset": You understand the difference between building a Project (for one client) and a Platform (for many). You value standardization over customization. • AdTech Experience (Bonus): Familiarity with concepts like VAST, OpenRTB, and Campaign workflows is a major plus. The Tech stack • Language: TypeScript (Node.js) • Infrastructure: AWS Serverless (Lambda, API Gateway) • Database: DynamoDB (Hot Data), Aurora Serverless (Relational), S3 (Assets) • IaC: Terraform / AWS CDK • CI/CD: GitHub Actions To Apply please go through our recruitment partner Bravuras site: https://ledigajobb.bravura.se/en/jobs/7188548-lead-backend-developer-to-danads
