About EverUp We’re a UK startup making gift-card shopping rewarding. Our mobile app (React Native) and web (React) run on a serverless AWS backend. We’re hiring a Backend Cloud Engineer to evolve and maintain the APIs, databases, and services that power payments, wallet, rewards, and near-real-time features. The role You’ll work across our event-driven, serverless stack to maintain and evolve production systems. That means adding features, fixing bugs, improving performance and cost, tightening security, and raising reliability—while collaborating closely with Mobile/Web. What you’ll do Maintain and evolve AWS Lambda microservices behind Amazon API Gateway (HTTP/REST & WebSocket) and AWS IoT Core ; implement authentication/authorization via Cognito User Pools (JWT) and Lambda authorizers for REST/HTTP. Maintain and optimize data models and access patterns in DynamoDB and MySQL (RDS); handle indexes, migrations, and query performance. Maintain asynchronous workflows using SQS/SNS (idempotency, DLQs, retries) and keep observability healthy with CloudWatch metrics/logs and alarms. Maintain and improve our IaC (AWS SAM/CloudFormation), CI/CD pipelines, and environment promotions. Integrate and support third-party services used for payments, open banking, notifications, fraud/risk, analytics and support tooling. Troubleshoot production issues, drive RCAs, and implement preventive fixes and runbooks. Uphold security best practices (least-privilege IAM, secret management, input validation, auditability). Tech you’ll touch AWS Lambda, API Gateway (REST/WebSocket), Cognito, DynamoDB, RDS MySQL, SQS/SNS, S3, IAM, CloudWatch, CloudFormation/SAM, EC2, ECS, plus fintech/comms integrations (Open Banking/PSP, Gift Cards, Analytics, Messaging, Support, and Risk assessment tools). Must-haves 8+ years building/maintaining production backends; 4+ years with AWS serverless (Lambda, API Gateway, DynamoDB). Proficiency in JavaScript/Node.js; strong REST API fundamentals and event-driven patterns. Solid SQL/NoSQL skills (schema design, indexing, query tuning). Experience maintaining IaC (SAM/CloudFormation) and CI/CD (Code Pipeline). Security-first mindset and practical debugging/troubleshooting chops (OWASP). WebSocket/API Gateway connection management and real-time features. Payments/fintech and fraud/risk integrations. Observability practices (dashboards, tracing, log correlation) and SLOs. Elastic Beanstalk familiarity and data pipelines/warehousing exposure. How we work Remote-first within UK time zone, startup-paced, with high ownership. We value clean code, small safe changes, and excellent operability. Hiring process Intro call Technical deep-dive (systems design discussions focused on maintainability and evolution) Practical walkthrough (IaC/API/data-modeling maintenance scenario) Founder/lead chat & references Equal opportunity We’re an equal-opportunity employer and welcome every background and perspective. How to apply Send your CV, GitHub/portfolio, and a brief note describing a production backend you maintained/evolved and the reliability or cost improvements you delivered. Kindly included your latest employment emoluments.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
