As a Senior Backend Engineer at Apollo, you'll be a critical part of a fast-growing company, working on a cross-functional team to build highly scalable systems and set the bar for how we engineer. The way we build has changed: this is an AI-native role. We're not looking for someone who also uses AI, we're looking for someone who thinks with it, forms their own hypotheses, pressure-tests what AI produces, catches its errors, and design more robustly than they could alone.
You'll work in an open, collaborative environment, give and receive hands-on mentorship, and have real opportunities to grow. You'll interface daily with design, front-end, analytics, product, and teams beyond Engineering. You enjoy working cross-functionally to solve hard problems and make an impact. You strive for quality, are obsessed with improving it, automation, monitoring, squashing the bugs that sneak through and you're always investigating performance improvements and better ideas.
Must have: Curiosity, AI-native engineering judgment, communication skills, problem solving.
Nice to have: BS or MS in Computer Science, Computer Engineering, or similar; GCP, Kubernetes, Docker, Mongo, Redis, Ruby on Rails, Microservices, Machine Learning

Both. Apollo posts both remote and in-person roles and lets you work from home or from an office hub. In a recent snapshot of open roles, most were remote (concentrated in the US, with some Canada and India openings) and the rest were hybrid tied to a specific hub city.
Yes. Apollo states that due to compliance requirements there is a small number of countries where it cannot allow remote work, whether temporarily or permanently. Roles that offer visa sponsorship or support are flagged directly in the individual job posting.
Apollo's team spans 22+ countries, anchored by office hubs in San Francisco (HQ area), Austin, Salt Lake City, London, and Mexico City. Hybrid roles are generally attached to one of these hub cities.
Apollo's process typically runs four stages: a 30-minute recruiter interview, team interviews with two to four members one-on-one, a skills assessment or AI-powered task for certain roles, and a final interview with senior leadership.
Highlights include flexible time off with no counted vacation days, competitive pay with performance bonuses and equity for most roles, global healthcare coverage (medical, dental, and vision in supported countries), office and learning stipends, and mental health and coaching support for employees and dependents.
US roles list salary bands tiered by location, for example a higher band for San Francisco, New York City, and Seattle and a separate band for other US locations. Roles outside the US may not show a published band, and applicants can request the range during the interview process.
