AdTech Engineer - Colombia - Contract

About Very
(Remote – Colombia)
Very is a fully distributed technology firm led by expert problem-solvers who create efficient, scalable solutions that move commercial, industrial, and consumer products from pilot to production in record time.
We believe that real innovation happens in the grind — working shoulder to shoulder with clients who are building the future. Our team thrives on that energy. When we’re not helping clients deliver business-critical outcomes, we’re refining our craft and celebrating what it means to do hard things well.
We’ve built a collaborative, tight-knit culture that thrives in both remote and in-person settings. We’ve won numerous workplace awards over the years, including Great Place to Work certification and recognition from Parity.org as a Best Company for Women to Advance.
Our clients include well-known brands like Vizio, Peloton, Clear, iHeart Radio, and Fellowes — all determined to leverage connected devices and AI to drive meaningful impact. Our job is simple: help them win.
As a Senior AdTech Engineer, you'll join a client's engineering team through Very's staff augmentation model, working as an embedded member of their team on programmatic advertising infrastructure. You'll work across the ad serving pipeline, from bid request handling through creative delivery, in high-throughput, low-latency environments on AWS.
This role is hands-on and long term. You'll work in the client's codebase, tools and processes, take part in their code reviews and on-call rotation, and report day to day to their engineering leads, while staying part of the Very team. At Very, a senior engineer has deep expertise in their specialty and works independently in their domain without needing detailed direction.
This is not an easy role. You'll work under real deadlines with a client who expects you to be available, proactive and delivering from day one. If you like doing hard things well, you'll fit right in.
What You’ll Be Working On
As an embedded member of the client's engineering team, you'll:
Build and maintain real-time bidding (RTB) infrastructure, including the bid request/response lifecycle, auction logic and win notification handling
Integrate with ad server platforms, including tag management, creative rendering and VAST compliance
Design and operate AWS systems that scale elastically under variable, auction-driven traffic
Build and support data pipelines for bid stream processing, event logging, reporting, attribution and frequency capping
Optimize for low latency, high throughput and cost-efficient architecture at volume
Take part in the on-call rotation and help maintain system health, performance and reliability
Collaborate across engineering, product and business stakeholders to deliver high-quality outcomes
Identify and proactively address potential technical or operational risks before they affect revenue or customers
You'll operate in an environment that includes:
Ad Tech: OpenRTB, IAB standards (ads.txt, sellers.json, VAST/VPAID), Spring Serve, header bidding (Prebid)
Cloud: AWS (EC2, ECS/EKS, auto-scaling, CloudFront, S3, Athena/Redshift)
Streaming: Managed Kafka (MSK) or Kinesis

Own deployments, CI/CD pipelines, logging, monitoring and alerting
Work within the client's engineering processes, tools and team rituals (standups, sprint planning, code reviews)
Take part in the 24/7 on-call rotation and help diagnose and resolve production issues
Support documentation and knowledge sharing within the team
Minimum Qualifications
General Experience
BS or higher in Computer Science, Software Engineering or a related field

Experience working embedded in client or distributed teams (staff augmentation or consulting)
Technical Proficiency
Strong knowledge of the OpenRTB specification and IAB technical standards (ads.txt, sellers.json, VAST/VPAID)
Experience with the real-time bidding lifecycle: bid requests/responses, auction mechanics and win notifications
Experience integrating with or building against ad server platforms
AWS scaling patterns for ad-tech workloads, including:
EC2/ECS/EKS auto-scaling
CloudFront for creative delivery
DynamoDB or Redis for low-latency lookups
S3 with Athena or Redshift for impression and event logging
