Staff Platform Infrastructure Engineer Jobs

Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn’t work together. So we expanded into software and started building integrated, omnichannel solutions – to help sellers sell online, manage inventory, offer buy now, pay later functionality, book appointments, engage loyal buyers, and hire and pay staff. Across it all, we’ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale. Today, we are a partner to sellers of all sizes – large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We’re building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same. The Role Square is looking for a passionate leader to develop, manage and support a group of Resellers. You will be responsible for planning, organizing, and leading Resellers focused on selling to SMB service based (examples: professional services, home & repair, beauty & personal care) with a hybrid scope to include restaurant and retail businesses. This role is a 2nd level leadership role. Your leadership will directly help Square drive revenue against our annual sales quotas. Your entrepreneurship spirit will be a valuable contribution to developing Square’s sales strategy, increasing the size and impact of the team and establishing a culture of crisp execution. This role reports directly to our Head o

About BlueConic: We are building products with AI at the core, and we build our products using AI.

We need a Staff Security Engineer who can secure that reality, not the SDLC of five years ago. In conjunction with the CISO you represent security across the product development lifecycle, lead threat modeling and vulnerability management, and drive secure coding practices in an environment where code review means reviewing agent output as often as human output.

Lead Security Engineer What you'll do Drive adoption of secure coding practices, including practices specific to AI-generated and AI-assisted code. Conduct security assessments, threat modeling, and risk analysis so threats are understood, documented, and mitigated. Automate security processes wherever it creates leverage, using scripts, AI agents, and AI skills as your default tools. Identify emerging classes of vulnerabilities and build solutions before they become incidents. Build and maintain security tooling, automation, and monitoring capabilities, including custom agents and skills for security workflows Threat model agentic systems: prompt injection, tool misuse, unauthorized agent privilege escalation, and data exfiltration through agent actions. Define guardrails and human-in-the-loop checkpoints for agent-driven changes to code and infrastructure. Set and enforce review standards for code produced by AI coding agents, including required checks before agent-authored changes reach production. Break large, cross-team security projects into individual tasks. Manage scope across teams and drive projects to closure.

MongoDB is hiring a Senior Manager, M&A Integration to help build and run the operational backbone for how MongoDB integrates its acquisitions, translating each deal thesis into a durable business outcome. As the Senior Manager, M&A Integration, you’ll help ensure acquisitions are integrated successfully and that the value outlined in each deal is realized. You may provide input during diligence to help flag integration risks, and you will lead integration planning and execution from LOI through post-close for assigned deals, reporting to the Chief of Staff to the CFO and partnering closely with our Corporate Development team. You'll coordinate across every functional team involved in a deal — Legal, HR, Finance & Accounting, IT, Go-to-Market, Marketing, and Product & Technology. You and the Chief of Staff together will support the Integration Management Office (IMO): defining workstreams, building the master integration plan, and supporting governance cadence for each deal. This is a hands-on execution role with real ownership of individual deal integrations. You’ll help build out MongoDB’s integration playbook – standard plans, checklists, templates – turning deal-by-deal efforts into more consistent, repeatable practices alongside the Chief of Staff. This role is ideal for someone who has led M&A integration workstreams before and knows how to bring structure to the ambiguity of a newly closed deal. You know how to drive cross-functional execution without formal authority, operate with autonomy within a defined framework, move fluidly between Day 1 planning, synergy tracking, and status reporting, and take ownership of outcomes rather than waiting to be told what to do. This role may flex across multiple concurrent deals depending on the pace of acquisitions. This role can be based in New York City, Austin, or Palo Alto for our hybrid working model or remotely in the United States. What You'll Do Integration Strategy & Planning Partner wit

About Us OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. The team's execution has been exceptional, and we're scaling at a remarkable pace. Our stellar early team comes with experience in companies like J.P. Morgan, Goldman Sachs, FalconX, Paypal, Affirm, Polygon, Kraken, Nium & others. We're backed by Accel, Lightspeed, NfX and other top-tier investors. Role Overview We're hiring a Staff Engineer to own the architecture of OpenFX's trading and hedging core — the systems that price a client's trade, execute it, and manage the risk we take on as a result. Two teams sit inside this scope: Trading owns the client's entire trade experience — quote generation, pricing strategy, the spread engine, and the trade lifecycle across GUI, API, and soon conversational AI. Its north star is Total Payment Volume, with Gross Revenue as the control metric. Hedging owns inventory and exposure management, risk management, hedging across venues through smart routing, market making, and WAC / PnL / net revenue calculation. You will be the senior-most individual contributor across both, responsible for the Client Trading Engine, Pricing Engine, Risk Management Engine, and Smart Hedging. This is a hands-on role. You will write code, set architectural direction, and be the person the organisation trusts to get the trade and risk path right. The problems here are genuinely hard and often under-defined. You'll take large architectural bets in a domain where correctness is measured in real money and latency is measured on a live client trade. Key Responsibilities Own the architecture of the Client Trading Engine, Pricing Engine, Risk Management Engine, and Smart Hedging. Break complex, ambiguous systems into smaller components with clear contracts, clear scope, and independent deliverability. Set and
