Javascript Developer

About the Project (Theirs, Not Ours) You’ll be embedded within our client's team (they're the cool startup, we just help them find cool people like you), a dynamic company experiencing hypergrowth (think 'hold on to your hat' levels of growth). You’ll be a key player in developing their core applications, working alongside and leading a team of engineers who are passionate about what they do (and probably fueled by copious amounts of caffeine). This is a chance to make a real impact, shape the technical direction, and be part of a company that's disrupting its industry (in a good way, we promise). Responsibilities (AKA \"Things You’ll Get Paid to Do\") Lead and mentor a team of engineers (think of it as being the Gandalf of the server-side), fostering a collaborative and high-performing environment (where code is law, but collaboration is king). Propose and implement scalable architectural patterns (because we're building a skyscraper, not a shed) to support the application's growth and ensure long-term maintainability (so it doesn’t collapse under its own weight). Define and enforce coding standards, best practices, and architectural guidelines (basically, you’re the code police, but in a good way… mostly). Follow and contribute to existing software design patterns (we’re not reinventing the wheel, but we’re definitely putting spinners on it). Identify and resolve data / process bottlenecks (before they become a \"Houston, we have a problem\" situation). Maintain and update the codebase (keeping it fresh like your memes). Collaborate with the Frontend team (those folks who make everything look pretty) to ensure new features are performant and meet design requirements (so it’s not just fast, it’s also fabulous). Conduct code reviews and provide constructive feedback (because even the best code can be better, and we’re all about growth). Troubleshoot and resolve complex technical issues (be the MacGyver of the backend). Requirements and Skills (What You Need to Bring to the Party) Proven experience working on high-throughput, high-availability applications, with experience in a lead role (you’ve been around the block, and you’ve got the scars… er, experience… to prove it). 7+ years of professional backend engineering experience (you’re not a rookie, you’re a seasoned pro). 4+ years of experience with NodeJS and MongoDB in a corporate environment (you speak fluent Node and Mongo). 2+ years of experience with Angular. Strong systems operations experience with AWS services (EC2, ECS, S3, Lambda, Rekognition, Elasticache, AmazonMQ, CloudWatch) (you know your way around the AWS jungle). Experience with Docker and container orchestration (you can wrangle containers like a boss). Demonstrated experience with DNS, VPNs, Networking, Firewalls, static asset delivery, application load balancing, and auto‑scaling (you’re basically the network whisperer). (Preferred) Experience working with AI (because the future is now, and it’s probably sentient). Strong understanding of web design best practices, standards, and modern web application development trends (you’re not stuck in ). Excellent communication and leadership skills (you can explain complex things without making people’s eyes glaze over), with the ability to mentor and guide team members (you’re not just a boss, you’re a mentor). Proven ability to make sound technical decisions and drive projects to completion (you’re the captain of this ship, and you’re not afraid to steer). Experience in technical planning and roadmap development (you’re not just building the road, you’re drawing the map). Why This Opportunity? Work directly with a fast‑growing, innovative startup (and be part of something big). Contribute to meaningful projects with a significant impact (your code will actually matter). Gain valuable experience in a dynamic and collaborative environment (where you’ll actually enjoy coming to work). Opportunity to grow your skills and advance your career into a leadership role (your mom will be so proud). Work with a company that is being supported by a well‑respected staff augmentation company, Sonatafy (that’s us again We’re the matchmakers of the tech world).
